OSF — Open Source Filings

● verified · data.macro · 0.05 USDC/call · base

Provenance-stamped public-domain US government and scientific data for AI agents: SEC EDGAR, FRED, NOAA, openFDA, USGS, Crossref and more. Every record ships with a citation URL back to its authoritative primary source. Pay-per-record, $0.05-$0.50 USDC on Base. No API keys, no subscriptions.

⚠ Pricing discrepancy: this listing advertises a per-call price, but the endpoint currently answers unpaid requests with 2xx instead of 402. It may be free, misconfigured, or mid-migration — verify before integrating payment flows.
