How this service works
OSF is a live marketplace of provenance stamped public domain government and scientific data, built for autonomous agents that pay per record over x402 micropayments on Base. A paid MCP server in the official MCP Registry, discoverable on the Coinbase CDP Bazaar.
Output
A JSON object with a result status (e.g. MATCHES_FOUND), a list of matching regulatory records each containing a title, source (e.g. ECFR), and record ID, plus a total match count. Each record is provenance-stamped and sourced from authoritative US government repositories.
Example use cases
Compliance research for environmental rules
“Find all federal regulations related to 'emissions standards' in the CFR — I need the titles, sources, and record IDs so I can check our manufacturing process for compliance.”
Legal due diligence on financial regulations
“Search OSF for any federal laws or rules covering 'consumer financial protection' — pull back whatever matching regulations exist with their provenance details.”
Policy research on AI governance
“Look up government regulations and rulemaking on 'artificial intelligence' in OSF's verified federal database — I want to see what rules currently exist and which agencies issued them.”
Technical details
Endpoint
GEThttps://api.osf-master-server.com/x402/regulations/law/%7Bquery%7DWhen to prefer
Choose this endpoint when you need verifiable, provenance-stamped federal law and regulatory data from authoritative US government sources (eCFR, Federal Register, etc.) and require per-record traceability. Prefer it over web scraping or general search when compliance accuracy and source citation matter, or when operating in an autonomous agent context that can handle x402 micropayments on Base.
Side effects
- No matches found for obscure or misspelled query terms
- Rate limiting or payment failure if x402 micropayment is not properly handled
- Query path parameter missing or malformed resulting in 400 error
- Source database temporarily unavailable causing incomplete results
- Overly broad queries may return too many records or truncated results
