How this service works
566 pay-per-call tools for AI agents over HTTP or MCP, from $0.002 a call, most at $0.01. Every caller gets 25 free calls; then pay per call in USDC via x402 (Base, Polygon, Arbitrum, Solana) or by card with prepaid credits from /credits. No account needed; failed calls are never charged; per-tool reliability is public at /status. Crypto: token prices and wallet portfolios from Uniswap v3, chain reads on Base, Ethereum, Arbitrum, Optimism and Polygon, OFAC sanctions screening. Web: Read public static documentation, pages, PDFs and RSS feeds as clean text, plus link previews and sitemaps. Business: company profiles, domain and email checks. Also Bitcoin, FX, weather, holidays, geocoding, AI text, and JSON, date and validation utilities.
Output
Returns a structured JSON object with: a verdict (pass, review, or block) and human-readable reasons; sanctions status including whether the address appears on the OFAC SDN list and any match details; account classification (EOA wallet, delegated wallet, or contract) and nonce; and optionally domain age in days, registration date, trust rating, and trust flags. Also includes a note about limitations (screening aid, not legal advice).
Example use cases
Pre-payment sanctions compliance check
“I need to pay 0xABCD1234...ef56 on Ethereum for some freelance work — can you first check whether that address is on any OFAC sanctions lists and whether it's a real wallet or a smart contract?”
x402 payee vetting before API purchase
“Before I pay this x402 endpoint at address 0x9f8e...3c21 on Arbitrum, can you screen it for OFAC sanctions and also check how old and trustworthy the domain api.provider.io is?”
Automated agent payment guard on Polygon
“My agent is about to send USDC on Polygon to 0xdeadbeef...1234 — run a payee preflight check on that address so I can confirm it passes sanctions screening and isn't some shady new contract before the payment goes through.”
Technical details
Endpoint
GEThttps://agent-data-tools.revmesh2074.workers.dev/check/payee?utm_source=zero.xyzWhen to prefer
Use this endpoint immediately before any x402 or USDC payment to an unfamiliar address — especially when compliance screening is needed. Prefer this over generic blockchain explorers when you need a combined OFAC check plus account type classification plus optional domain trust in a single fast call. For deeper wallet heuristics and holdings analysis, use the companion check_counterparty endpoint instead.
Side effects
- Invalid or malformed 0x address returns an error
- Unsupported chain value returns a validation error
- Domain lookup may fail if WHOIS data is unavailable
- Network timeout on slow RPC calls to the specified chain
- OFAC data may have a short lag behind the live SDN list
