Data

Pay-per-call data & security tools for AI agents: honeypot / rug-pull token security checks (verdict OK/CAUTION/HIGH_RISK/AVOID, 8 chains), residential-IP web scraping that reaches sites blocking datacenter/cloud IPs (clean markdown), live token & DeFi market data, and global company data (US SEC EDGAR, UK Companies House, FR KYB/SIREN). Each route is a named job at a fixed USDC price. x402 on Base, no account, no API key.

Pay from $0.003 to $0.10 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.

Conservative undercount: only USDC settlements via facilitators we measure are counted. A measured floor, not an estimate.

Top buyer share is a concentration signal, not part of the ranking score.

OVER TIME

All charts share the 24h window selected here. Every series is also served as JSON at /api/v1/services/x402-farm/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). The on-chain series roll up hourly, so the latest day can be up to about an hour behind; distinct buyers are counted per payout address, so a service that settles to more than one address is an upper bound.
