Keyless pay-per-call APIs for AI agents: 30 tools across compliance (sanctions/AML, HS codes, company/VAT), safety (chemical, FDA drug/device, product recalls), web (search, reader, screenshot, tech-stack), and data (SEC financials, electronic parts, jobs, local places). Pay per call with USDC on Base via x402. No account, no API key.
Pay from $0.008 to $0.04 per request in USDC on Base, settled onchain via the x402 protocol, no signup, no API key needed.

risk clean
No deterministic risk flag. Risk fires only on an exact blocklist match, or a reserved-brand name with a mismatched verified payTo. Never from low uptime, a high price, or a model guess.

All charts share the 30d window selected here. Every series is also served as JSON at /api/v1/services/toolcall/price, /scores, /volume and /buyers. On-chain volume and distinct buyers are measured over the service's settlement address and are a conservative undercount (only settlements that reach a measured facilitator are counted).
