Successful endpoint responses are JSON.\n\n## For AI Agents\n- **Agent-readable catalog**: https://algorand.ottoai.services/llm.txt\n- **Storefront**: https://algorand.ottoai.services/\n- **Documentation**: https://docs.useotto.xyz/acp-swarm/x402\n\n## Payment\n- **USDC** on Algorand MainNet (`algorand:wGHE2Pwdvd7S12BL5FaOP20EGYesN73ktiC1qzkkit8=`), Algorand Standard Asset 31566704\n- x402 v2, `exact` scheme; verification and settlement via facilitator.goplausible.xyz\n- Read-only data only. This rail mounts no fund-moving routes and no POST routes.\n\n## Available Services\n\n### Market & Token Intelligence\n- **/crypto-news** ($0.001) - Importance-ranked crypto headlines with per-article source links and publish times, plus a sentiment-scored market brief, from Otto's own news engine. Regenerated hourly over a 6h look-back (widened to 12/24h on a quiet window — the report states the period it covers); `meta` carries the snapshot's build time, its age in seconds and a fresh/stale verdict against that cadence.\n- **/news-recaps** ($0.003) - A tight 4-6 sentence crypto market recap an agent can ingest whole: overall direction and why, the 2-3 developments that matter, and anything notable on the top-10 board — distilled on demand (served while fresh, ≤1h) from the same live news engine behind Otto's top-ranked /crypto-news feed. The one-paragraph state-of-market; buy /crypto-news when you want the full report. Beside the prose, stories[] carries the ranked board as named typed fields — rank, title, whyItMatters, url, publishedAt, source (linked to the window's source articles by exact title; null when unmatched, never a guessed link) — with storiesStatus / articlesStatus and the analysis window, so an agent parses the same shape /crypto-news sells instead of regexing the board.\n- **/base-ecosystem-news** ($0.001) - Base-chain ecosystem news for Base-native agents, not the general crypto firehose. Up to 12 Base-scoped headlines from the last 48h, each with its own permalink and publication timestamp, screened against the general /crypto-news feed; `screen` states what was dropped. The AI topic read is optional and is withheld, never padded with macro, when there is no Base coverage. Refreshed hourly from cache; a read past the freshness window pulls inline.\n- **/filtered-news?topic={topic}** ($0.001) - AI-filtered crypto news and Twitter search for non-token topics (airdrops, DeFi trends, etc). Max 2 words.\n- **/twitter-summary** ($0.001) - Quick pulse check from crypto Twitter. Breaking news, trending narratives, and sentiment shifts at a glance.\n- **/token-details?symbol={symbol}** ($0.001) - Token price, market cap, volume, supply, and basic metrics. Works for any listed token.\n- **/token-alpha?symbol={symbol}** ($0.005) - Premium token intelligence: price metrics, news, Twitter sentiment, and futures data. Find out why your token is moving.\n- **/kol-sentiment** ($0.003) - Sentiment and token mentions from an Otto-curated crypto-KOL feed. Real trading signals, trending token picks, and sentiment from influencers who move markets.\n- **/trending-altcoins** ($0.002) - Top 3 hottest altcoins traders may want to ape into, based on news and Twitter analysis. DYOR.\n- **/mega-report** ($0.05) - Alpha & Intel Report — daily crypto market intelligence: headlines, Twitter sentiment, KOL alpha, trending altcoins, and yield opportunities in one report.\n- **/token-security?address={address}&chain={chain}** ($0.001) - Token security scanner — is this token safe to buy? Honeypot, rug-pull, and scam detection for any token contract — flags can't-sell traps, hidden mints, malicious buy/sell taxes, and holder concentration. Powered by GoPlus across 8 chains.\n- **/base-season** ($0.002) - Base social intelligence: a current Base sentiment summary + the quality-screened Base tokens (CoinGecko-listed, market-cap/age/liquidity gated) that are catching attention on Base — each row labelled with the basis it stands on (`rankedBy`: measured trusted-KOL signal, or the on-chain screen plus open engagement), with per-token KOL mention counts and verbatim quotes where a KOL is actually behind it. Every tweet and quote served is inside a published recency window (`evidenceWindowDays`), and the board publishes its own coverage arithmetic. Includes the overall crypto-KOL market-sentiment backdrop, with an explicit reason when that leg is unavailable. The social-intelligence wedge for Base — who is saying it, not who pumped. Served from a cached snapshot while fresh (≤1h) and regenerated on demand when a read finds it stale.\n- **/rh-season** ($0.001) - Robinhood Chain memecoin intelligence: the rug-screened RH Chain (chainId 4663) movers. Hard liquidity + wash-volume gates filter the $0-liquidity honeypots that fake $1M volumes; every survivor carries rug-risk flags (thin liquidity, vol/liquidity anomaly, pool age, CoinGecko listing) plus trusted-KOL mentions with verbatim quotes and a synthesized RH Chain sentiment read. What is pumping AND whether it is real. The body also carries `movers`, the broader most-active tape BEFORE the hard gates, which is not rug-screened. Served from a cached snapshot while fresh (≤1h) and regenerated on demand when a read finds it stale.\n- **/tokenized-stock-movers** ($0.003) - Day movers for tokenized US stocks and ETFs on TWO rails in one call: Robinhood Chain (chainId 4663) and Base B20 (the Coinbase-issued tokens Otto lists, keyed by token address — B20 metadata is mutable, so the address is the identity); each rail reports its own `universeSize`. Gainers and losers by REAL day-over-day change of the UNDERLYING stock vs the prior NYSE session close (Finnhub quotes), with per-rail coverage counts. A token with no listing is named with its reason under `excluded`; a token that cannot be quoted at the time is counted as uncovered, not named. Off-hours values freeze; a tokenized share can trade at a premium/discount to the underlying. Refreshed every 15 minutes.\n- **/token-fundamentals?symbol={symbol}** ($0.003) - Structured token fundamentals by ticker symbol (resolves to the top-market-cap asset matching it): price, market cap, FDV, rank, 24h volume, full supply breakdown (circulating/total/max), ATH + drawdown from ATH, ATL + recovery, ROI windows (24h/7d/30d/60d/1y), categories, and project links — clean JSON an agent can consume field-by-field. Fundamentals snapshot, not a streaming price feed.\n- **/token-price?token={token}** ($0.001) - Live DEX token price in USD by ticker symbol or contract address across Base, Ethereum, Solana, Polygon, BSC, Arbitrum, Optimism and Avalanche (bare 0x tries Base then all chains, else network:address). Symbols resolve to the canonical top-market-cap asset — squat-proof. Flat JSON: price, 24h change, volume, market cap, FDV, liquidity — echoes the matched deployment. Token price, crypto price, DEX price. $0.001 per call.\n\n### DeFi & Markets Data\n- **/yield-alpha** ($0.002) - Best DeFi yield opportunities across stablecoins, ETH, and BTC with risk ratings and APY comparisons.\n- **/funding-rates?symbol={symbol}** ($0.001) - Cross-venue funding-rate arbitrage + crowded-positioning radar: live perp funding rates, open interest, global & top-trader long/short ratios, whale positions, and liquidations across Binance, OKX, Bybit, Hyperliquid, and more. Omit symbol for the whole-market overview; pass one (e.g. BTC) for the per-exchange breakdown. (Hyperliquid-only perp data: use hyperliquid-market.)\n- **/defi-analytics?protocol={protocol}** ($0.001) - Where DeFi capital is flowing — TVL rankings, fastest-growing vs bleeding protocols, chain-by-chain breakdown, and per-protocol deep dives. Track capital rotation and protocol health. Powered by DefiLlama.\n- **/tradfi-data?symbol={symbol}** ($0.003) - TradFi macro intelligence: indices, VIX, DXY, treasury yields, commodities, and individual stock quotes with moving average context.\n- **/hyperliquid-market?asset={asset}** ($0.001) - Hyperliquid perpetuals market data: live mark/oracle price, funding rate, open interest, max leverage, and size specs for any tradable asset.\n- **/yield-markets** ($0.001) - DeFi yield farming markets with live APYs across Aave V3 and Morpho on Base, Ethereum, and other major chains. Find the best stablecoin yield (USDC) and ETH yield for idle capital: returns supply APY, TVL, and vault/market addresses per token, filterable by protocol, chain, or token symbol. Compare DeFi yield rates across lending markets and vaults before depositing.\n- **/stablecoin-watch** ($0.001) - Is USDC/USDT/DAI holding its $1 peg, and is stablecoin supply growing or shrinking (risk-on vs risk-off)? Live peg deviation (bps), circulating supply + 1d/7d/30d flow, market dominance and chain spread for the top 30 USD stablecoins, plus downside depeg alerts for any coin trading >0.5% below peg. Sourced from DefiLlama (public). Served from a cached snapshot while fresh (≤1h) and regenerated on demand when a read finds it stale.\n- **/market-risk** ($0.002) - Composite crypto market-stress digest: a 0-100 score (low/moderate/elevated/high) blended from global USD-stablecoin depeg health (DefiLlama) and Base on-chain DEX exit-liquidity, with a per-leg breakdown and an AI risk line. Stablecoin systemic + Base liquidity microstructure only (not derivatives/sentiment). Both legs required for a score. Every read older than an hour regenerates the score inline (the buyer waits a few seconds) — never an older reading; public sources, pay-per-call.\n- **/protocol-revenue-leaders** ($0.001) - Which protocols earn the most — and who is accelerating? Top 30 DeFi protocols by 24h fees, each with revenue, take-rate (the cut the protocol keeps vs fees users pay), 7d/30d trend and category, plus total DeFi fees & revenue. A fundamentals screen (fee/revenue economics), distinct from TVL. Sourced from DefiLlama (public). Served from a cached snapshot while fresh (DefiLlama fees are daily aggregates) and regenerated on demand when a read finds it stale.\n- **/equity-intel?ticker={ticker}** ($0.003) - SEC filings and company fundamentals by US-listed ticker: revenue, net income, YoY growth, margin, EPS, assets, liabilities, leverage and cash, plus recent 10-K, 10-Q and 8-K filing links and an AI analysis. SEC EDGAR source; a ticker with no USD issuer fundamentals (funds, non-USD-only or stale filers) is refused with a 404, uncharged. Fundamentals and filing research, not a stock-price feed.\n- **/financial-statements?ticker={ticker}** ($0.003) - Financial statements by ticker — the SEC statement set for a US-listed company: income statement, balance sheet and cash flow, up to five fiscal periods on both an annual and a quarterly basis. Every figure names the XBRL concept it was filed under, the filing and date it came from, and whether it was filed, reconstructed from year-to-date figures or computed from named lines; a period a later filing restated is flagged with the earlier value; a period the filer did not tag is an explicit null, never carried forward. Plus the SEC filing index: 10-K, 10-Q and 8-K with the 8-K item codes and EDGAR links. A fund vehicle or a filer that reports only in a non-USD currency has no statements: that is refused as `not_applicable` and nothing is charged. Public-domain SEC EDGAR. $0.003 per call.\n- **/earnings-calendar?ticker={ticker}** ($0.003) - Earnings calendar and surprise history for a vendor-resolved equity: next report date/session with EPS and revenue estimates, latest reported EPS versus estimate, surprise percentage, and up to four quarters of history, which may be fewer. Monetary estimates retain Finnhub payload units because the captured feed does not identify a currency. Event-window price drift is explicitly unavailable rather than inferred.\n- **/analyst-ratings?ticker={ticker}** ($0.003) - Analyst consensus for a vendor-resolved equity: the latest buy/hold/sell distribution (strong buy · buy · hold · sell · strong sell counts, total, and a deterministic consensus label) plus up to six months of the same distribution so an agent can read the drift — is the street moving toward or away from the name. Vendor counts (Finnhub), label rule stated in the payload. No price targets and no per-analyst grade actions are served.\n- **/equity-news?ticker={ticker}** ($0.003) - Latest company news for a vendor-resolved equity: licensed Finnhub headlines from the trailing seven days with publication time, source, and summary. Only articles that name the company or print its ticker as a standalone uppercase symbol are served — labelled `primary` when the headline does, `mentioned` when only the summary does; a ticker that is also an English word (for example ON or IT) can match an unrelated all-caps phrase. A week with no such articles is refused as `no_recent_news` and nothing is charged. Redirect URLs withheld; no sentiment is fabricated.\n- **/dividend-intel?ticker={ticker}** ($0.003) - Cash-dividend intelligence for a vendor-resolved equity from licensed Tiingo end-of-day history: TTM dividend/share and yield against the latest close, latest dividend, split-adjusted complete-year growth, the last eight payments, split events, and a cut-detection checklist with explicit coverage. Payout ratio, forward ex-dates and declaration/record/payment dates are not served (not in the Tiingo feed). Cash values retain Tiingo payload units because the feed does not identify a currency.\n- **/macro-regime** ($0.003) - Daily US macro-regime snapshot from licensed Alpha Vantage series: 10-year Treasury yield, effective federal funds rate, three-month rate changes, CPI index and YoY inflation, plus a mechanical rates-direction/inflation-direction label with disclosed thresholds. Three upstream calls per daily refresh; scanner context only.\n- **/technical-signals?ticker={ticker}** ($0.003) - Daily technical snapshot for a vendor-resolved equity from licensed Tiingo adjusted closes: Wilder RSI-14, 20-session momentum, SMA-20/SMA-50, price distance from each average, above/below/mixed trend state, and the latest observed golden/death cross. Price and averages retain Tiingo payload units because the captured feed does not identify a currency.\n- **/pools-search?query={query}** ($0.001) - Search DEX pools across Base, Ethereum, Solana, Polygon, BSC, Arbitrum, Optimism and Avalanche by token symbol, name, or contract address. Returns pool address, DEX, price USD, 24h volume, liquidity (TVL), FDV, 24h price change and 24h txns as flat JSON numbers — no nested joins. Pool search, pool finder, DEX pools, liquidity pools, onchain pool lookup. $0.001 per call.\n- **/stock-pools?stock={stock}** ($0.001) - Find the DEX pools a tokenized US stock or ETF is a member of, on Robinhood Chain, Base, BNB Chain or Solana. Returns pool id (v4 ids kept distinct from v3), DEX, the side the asset is on, the counterpart with an evidence-backed class, reported USD liquidity, 24h volume and pool age. Membership discovery only: a provider-covered read, not a census; no APR, no execution; a return is the asset's only where it is the base token. $0.001 per call.\n- **/pools-trending?network={network}** ($0.001) - Trending DEX pools right now — Base, Ethereum, Solana, Polygon, BSC, Arbitrum, Optimism, Avalanche, or network=all for cross-chain across those same 8. Top 10 hottest pools ranked by GeckoTerminal 24h trending: pool address, DEX, price USD, 24h price change, 24h volume, liquidity (TVL), FDV, 24h txns as flat JSON numbers. Trending pools, hot pools, top movers, momentum screener, what is pumping. $0.001 per call.\n- **/pm-markets** ($0.001) - Top Polymarket prediction markets RIGHT NOW: the 25 highest-volume open markets with live odds (outcome probabilities), best bid/ask, spread, last trade price, 24h + total volume, liquidity, 1d/7d price change, end date and event link. Flat JSON, refreshed every 5 minutes. Prediction market odds, Polymarket data, event probabilities, market sentiment. $0.001 per call.\n- **/pm-crypto** ($0.001) - Crypto prediction markets on Polymarket: the highest-volume open BTC, ETH and crypto markets with live odds (outcome probabilities), best bid/ask, spread, 24h + total volume, liquidity, price change and end date. \"Bitcoin above X\", price targets, ETF and protocol events — what the prediction market ACTUALLY prices in, as flat JSON refreshed every 5 minutes.

Polymarket odds movers, biggest prediction-market moves, event probability shifts, market momentum. $0.002 per call.\n- **/chain-status** ($0.001) - Base chain status from Otto's configured RPC: latest, safe, finalized and pending heads with validated mined block hashes; pending hash nullable and provisional. Public source ID, per-head observation times and retrieval window disclose non-atomic RPC reads. Base fee, congestion, finality lag and block age at observation, separate from cache staleness. Refreshed every minute. $0.001 per call.\n- **/gas-oracle** ($0.001) - Base gas oracle from Otto's own RPC: current base fee (wei+gwei), legacy gas price, and slow/standard/fast EIP-1559 priority-fee tiers (p25/p50/p90 over the last 20 blocks) with a ready-to-sign maxFeePerGas per tier. Unlike the crowded gas shelf it PUBLISHES the formula, so every tier is reproducible from the response. Flat JSON, refreshed every minute. Base gas oracle, gas price, priority fee, EIP-1559, maxFeePerGas. $0.001 per call.\n- **/insider-trades?ticker={ticker}** ($0.003) - SEC Form 4 insider trades for any US-listed company by ticker: who bought and sold (officer/director/10% owner), purchase vs sale counts and dollar values (SEC codes P/S: open-market or private), net purchase-sale balance, shares held after, filing links — hourly snapshot; 4/A-amended windows withheld once detected (~1h lag): unpaid 503.

Smart money, fundamentals. Public-domain SEC EDGAR. $0.006 per call.\n- **/equity-smart-money-brief?ticker={ticker}** ($0.10) - Smart-money filing brief for US-listed companies by ticker: SEC Form 4 insider purchases vs sales with filer roles, Schedule 13D/13G beneficial-ownership filing events (subject-validated; not 13F), fundamentals with one-time-item flags (TTM where available), regime-aware filings cadence — ONE AI read of the filing record. Observed filings only; screened for buy/sell advice. Public-domain SEC EDGAR + AI. $0.10 per call.\n- **/form-144-filings?ticker={ticker}** ($0.005) - Form 144 filings by ticker — SEC notices of PROPOSED insider sales, filed BEFORE the Form 4 that reports the executed trade: who intends to sell, units, the filer's own market-value estimate, broker, approximate sale date and Rule 10b5-1 plan dates. The earliest public read on insider selling intent; a notice is not a completed trade and may never be executed. Up to the latest 20 notices in a 90-day lookback, which may be fewer. Public-domain SEC EDGAR. $0.005 per call.\n- **/13d-activist-watch?ticker={ticker}** ($0.005) - Schedule 13D and 13G activist stake filings by ticker: every beneficial-ownership filing made about a US-listed issuer in the last 365 days, each validated against its own cover page so a company's outbound filings about OTHER companies are excluded. Returns 13D vs 13G counts, amendments, reporting-person names and EDGAR links. 13D is the schedule filed without a passive/qualified certification. Public-domain SEC EDGAR. $0.005 per call.\n- **/form-4-feed** ($0.003) - Latest insider trades feed across ALL US-listed companies — the 20 most recent SEC Form 4 filings by acceptance time, not one ticker at a time: issuer ticker and name, who filed and their role, transaction code (P purchase / S sale / A award / M exercise / F tax), shares, price, value and shares held after, with EDGAR links. Refreshed every 15 minutes. Derivative-only filings are excluded and counted. Public-domain SEC EDGAR. $0.003 per call.\n- **/8k-material-events?ticker={ticker}** ($0.003) - 8-K filings by ticker — the item-coded SEC material-event feed: up to 20 Form 8-K filings a US-listed company filed in the last 90 days (flagged `truncated` when there were more), tagged with the SEC's own numbered item codes and official titles (1.01 material agreement, 1.05 cybersecurity incident, 2.06 impairment, 3.01 delisting notice, 5.02 officer or director change, 8.01 other events).

Every sub-score, weight, raw input, source plane and read time comes back with the number, plus the full breakpoint curve, so the score can be recomputed from the response.

Market structure, not a contract-security screen. $0.010 per call.\n- **/tokenized-equities?thesis={thesis}** ($0.001) - The live registry of tokenized US equities & ETFs on Robinhood Chain (chainId 4663): symbol, canonical token address, decimals, listed-on-rail routability, and the EXECUTABLE buy price — what a $100 buy actually pays per token on the live route, at the route's minimum output — published next to LI.FI's catalog reference price and `referenceDeviationPct`, the gap between them, so a stale catalog reference is visible rather than inherited. Every served row's token address is bound to a hand-verified identity pin; an unpinned address is refused, never published under a ticker. The on-chain settlement layer for tokenized-equity exposure, not a data-coverage claim. Optional `?thesis=` filters the registry to a matched shortlist (per-row match reason + an honesty contract). Informational only; not a quote or a recommendation. Flat JSON, refreshed hourly. $0.001 per call.\n\n### Portfolio & Accounts\n- **/portfolio?userId={userId}** ($0.001) - Multi-chain portfolio snapshot with token balances and yield positions for a user's Otto AI Safe accounts across Base, Ethereum, Arbitrum, Polygon, BSC, Avalanche, and Solana.\n- **/transaction-history?userId={userId}** ($0.001) - Trade and transaction history for a user's Otto AI Safe account — swaps, bridges, deposits, withdrawals with timestamps and explorer links.\n- **/supported-tokens?search={search}&chainId={chainId}** ($0.001) - Search supported ERC-20 tokens by symbol or address across 6 chains (Base, Ethereum, Arbitrum, Polygon, BSC, Avalanche). 5000+ tokens from CoinGecko.

A drop-in nslookup/dig replacement for agents, resolved over DNS-over-HTTPS (DoH) with redundant resolvers and automatic failover. Keyless, pay-per-call, structured JSON.\n- **/whois-lookup?domain={domain}** ($0.001) - Registration data for any domain, straight from authoritative RDAP registries (the structured WHOIS successor): registrar, ICANN/EPP domain status codes, creation, last-updated and expiration dates, authoritative nameservers, and DNSSEC delegation. The fast, license-clean way for an agent to vet a domain, sender, or counterparty. Keyless, structured JSON, pay-per-call.\n- **/domain-age?domain={domain}** ($0.001) - Domain age and registration intel from authoritative RDAP/WHOIS records: exact creation date, age in days and years, expiration date and days-until-expiry. The fast trust and risk signal agents use to vet a counterparty, link, or sender and to flag newly-registered or soon-to-expire domains. Returns structured JSON, keyless, pay-per-call. ccTLDs without RDAP return an uncharged 503.\n- **/domain-report?domain={domain}** ($0.02) - One call returns the full domain profile for vetting, deliverability, or phishing/fraud checks: live DNS (A/MX/NS + record counts), RDAP/WHOIS registration (registrar, domain age, expiry, status, DNSSEC) and email authentication (SPF, DMARC policy, detected DKIM selectors) — plus a one-line summary. Bundles three lookups into one hourly-fresh read. Keyless, license-clean, pay-per-call.\n- **/web-extract?url={url}** ($0.005) - Turn any URL into clean, LLM-ready markdown — the main article extracted, nav/ads/boilerplate stripped, plus title, description and publish date. Renders JavaScript pages, articles, docs and PDFs. A keyless, pay-per-call web reader for agents that read the web on demand: RAG ingestion, research and summarization. Structured JSON, cached by URL for fast repeat reads.\n- **/web-links?url={url}** ($0.003) - Extract all links (hrefs) from any web page as structured JSON — every internal, external and anchor link, deduplicated, returned with a total count. Renders the page in a real headless browser, so it captures links injected after JavaScript runs that fetch-only scrapers miss. For crawling, sitemap building, link audits and site-structure mapping. Keyless, pay-per-call.\n- **/web-json-extract?url={url}** ($0.005) - Turn any URL into clean structured JSON for AI agents and RAG. An LLM reads the fully rendered page (JavaScript executed, SPAs included) and returns its title, a 1-2 sentence summary, key entities (people, orgs, products), and any prices, dates or notable numbers — even on pages with no schema.org or JSON-LD markup, no CSS selectors or schema to write. Just pass a URL. Keyless, pay-per-call.\n\n### Real-World Data\n- **/fx-rates** ($0.001) - Live + reference foreign-exchange (forex) rates, base USD. LIVE near-real-time mid quotes for the 12 most-traded currencies (EUR, GBP, JPY, CHF, CAD, AUD, NZD, CNY, HKD, SGD, SEK, KRW), refreshed every minute with an honest market-open/stale flag, PLUS the official ECB daily reference table for ~30 currencies. Derive any cross-rate or pair. For agents pricing cross-border ops, treasury, invoicing and FX conversion. Keyless, pay-per-call.\n- **/weather?location={location}** ($0.002) - Live weather for any city or lat/lon worldwide. Returns current conditions — temperature, feels-like, humidity, wind and sky — plus a 5-day forecast with daily highs/lows and precipitation probability.
