Browse the OSF catalog (FREE). Returns record_ids, prices, data types, and provenance URLs so an agent can choose what to purchase. Optionally filter by `source` (e.g. 'NVD', 'CISA_KEV', 'EPSS', 'GHSA', 'CWE', 'MITRE_ATTACK', 'SEC_EDGAR') or `data_type` (substring, e.g. 'CVE', 'Exploited', 'EPSS', '8-K', 'sanctions'). OSF aggregates verifiable public and openly-licensed U.S. government and scientific data across many verticals: security and vulnerabilities (CVE/KEV/EPSS/CWE/ATT&CK), sanctions and compliance (OFAC/EU/UK lists), SEC and corporate filings (EDGAR/13F/10-K/XBRL), economic and financial (FRED/BLS/BEA/Census/Treasury/World Bank), legal and regulatory (Federal Register/eCFR/Congress/court opinions), grants and procurement (USAspending/SAM/FEC/Grants.gov), science and research (OpenAlex/PubMed/arXiv/Crossref/clinical trials), geospatial and environmental (NOAA/USGS/EPA/FEMA), and AI/ML metadata (model hubs), among others. Every record carries a provenance URL pointing back to its authoritative primary source. Call get_record with a record_id to purchase the full record (x402 USDC micropayment on Base).

Returns the full record plus its provenance block linking back to the authoritative primary source (e.g. sec.gov, nvd.nist.gov, treasury.gov, congress.gov, ncbi.nlm.nih.gov, noaa.gov). OSF spans many verticals: security/vulnerabilities, sanctions/compliance, SEC and corporate filings, economic and financial series, legal and regulatory, grants and procurement, science and research, geospatial and environmental, and AI/ML metadata.
