Base URLhttps:
- POST/pl
/company$0.01Polish VAT whitelist check (official Ministry of Finance register). Verifies a company's VAT status by NIP and — uniquely — whether a given bank account number (NRB) is registered to that company in the tax register: the standard Polish invoice-fraud check before paying a supplier. Returns VAT status, REGON/KRS, address, registered-account count and the official consultation confirmation id (request_id). Companies only. - POST/x402
/preflight$0.01Preflight before paying an x402 service: is it working right now, and did it work the past 30 days? One live probe of the exact resource URL you intend to pay (status, latency, x402 validity, the payTo/price the service itself publishes in its 402, manifest presence) plus our own monitoring history of the host (30-day uptime, last check, recent changes such as payTo or price drift). Optionally verifies that the pay_to you intend to pay matches the live 402. Facts only — no scores. - POST/x402
/service-report$0.05Full reliability report on one x402 service from our own availability monitoring (~2 probes/day per host): daily probe series over 30 days (probes, ok, avg/max latency), uptime 7d/30d, all observed change events (up/down transitions, payTo drift, price drift, manifest appearing/disappearing) and the payment details as last observed in the service's own 402 responses. Returns 400 host_not_monitored (no charge) when we have no history for the host. Facts only — no scores. - POST/relay
/reddit-search$0.05Keyword-search all of Reddit (or one subreddit) for $0.05 per call — social listening for AI agents without login or API key. Returns matching posts with title, author, subreddit, score, comment count, permalink and timestamp, sorted by relevance, top, new, hot or comments, with an optional time window. Track brand mentions, monitor topics, surface community sentiment. Relayed live from a proven upstream source; if the source is down you get a 503 and pay nothing. Pay per call in USDC on Base. - POST/cz
/company$0.01Official Czech company check from the ARES register (Ministry of Finance, open data). Look up by ICO (exact) or search by name (up to 5 candidates). Returns official name, legal form code, VAT number (DIC), establishment and termination dates, registered address and NACE activity codes, with a direct ARES link. Companies only. - POST/eu
/vat$0.002EU VAT number validation (VIES) with predictable behavior for agents. Validates any EU VAT number against the European Commission's VIES service. Two modes: fast validation (may serve a cached result, labeled with its timestamp) and consultation-proof mode (always live, returns the official consultation number, requires requester identification). 'Not confirmed' does not imply the company is invalid. Machine-readable errors with per-member-state availability status. - POST/web
/contents$0.003Read any web page as clean LLM-ready markdown for $0.003 — the natural companion to /web/search. Send a URL, get back the readable core: title, headings, paragraphs, lists and links, stripped of scripts, styles, navigation and other boilerplate. Choose markdown or plain text and cap the size with max_chars (default 20000; a truncated flag tells you when the cut hit). Unreachable or non-HTML targets cost nothing. Pay per call in USDC, no account, no API key. - POST/eu
/eurc-peg$0.002EURC peg monitor — unique combined signal: the official ECB euro reference rate (USD/EUR) versus the live on-chain EURC/USDC price from the deepest Uniswap v3 pool on Base, returned as a deviation in basis points with both source values and timestamps. Tells agents holding or pricing EURC how far the on-chain euro stablecoin trades from the official euro. No input required. - POST/crypto
/feed$2Subscribe for 30 days to the change feed behind /crypto/scan: one cursor over the upstream advice ledger, all coins at once. Returns a handle and a cursor; polling is then free and unlimited: /crypto/feed/since returns every published change since your cursor — new signals, classification flips, status changes (PUBLISHED/STALE/INVALIDATED), score and entry-zone changes. Be first to know when the market state flips; the full advice per signal stays a separate paid call. - POST/nl
/insolvency$0.15Dutch bankruptcy and insolvency check against the official Central Insolvency Register of the Dutch judiciary (rechtspraak.nl). Detects published bankruptcy (faillissement), suspension of payments (surseance) and debt restructuring procedures. Best results with a KVK number. Returns procedure type, status, dates, court and a source reference per match, with explicit match-basis and coverage notes. A no_match means no publication in the currently searchable register. Companies only. - POST/nl
/supplier-screen$0.15Dutch supplier screening — pre-transaction check in one call: validates the EU VAT number (VIES), checks the official Dutch Central Insolvency Register for bankruptcy, suspension of payments or debt restructuring, and cross-checks the legal name against the VAT-registered name where available. Requires legal_name, kvk_number and vat_number. Returns factual attention items with a source reference per finding — no risk scores. Only charged when both registers were consulted. Companies only. - POST/news

Returns issuer, home member state, competent authority, DTIs and the official white-paper URL per match. Useful before trusting a stablecoin or token sold as EU-regulated. - POST/web

No execution, no custody, no position sizing. Each response names the next useful call. Paid per request; an empty list is a valid answer. - POST/eu

/want$0.01File what you want to buy from an agent-facing API and cannot buy today. Optional kind is typically one of coin, country, vies_country, monitor_host, sms_service — free-form values possible. The $0.01 fee is there to keep intents honest, not to sell you anything: it is not a purchase of the capability and no promise that it gets built. Optionally add the price per call you would pay and your expected monthly volume. Free alternative: POST /agent/request.
