Pay per record marketplace of provenance stamped US government and scientific data for AI agents: 4.8 million records across 76 official sources. Sanctions and debarment screening across eleven authorities (280,000+ parties), exploited CVE checks, 1.5M federal court opinions, SEC EDGAR, FDA recalls, 1.2M scholarly works. Every record carries a provenance URL to its authoritative primary source. USDC on Base via the Coinbase CDP facilitator; free machine readable catalog.
Pay from $0.01 to $0.08 per request in USDC on Base, settled onchain via the x402 protocol, no signup, no API key needed.

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.

RECENT CHECKS
OVER TIME
All charts share the 7d window selected here. Every series is also served as JSON at /api/v1/services/open-source-filings-osf/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.
Median across 14 endpoints. Use the selector to isolate one.
