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
Returns a JSON object containing the record's numeric ID, a status field, a nested data object with the record's domain-specific fields and a data_type label, the source identifier (e.g. CISA_KEV), and a provenance_url pointing to the canonical government or scientific source where the data originated.
Example use cases
Verify a CISA vulnerability before patching
“Get me OSF record 12345 in JSON — I need the full CISA Known Exploited Vulnerability details and the provenance URL back to CISA's site so I can confirm it before we prioritize patching.”
Cite government source in compliance report
“Fetch the OSF record for ID 9874 and give me the provenance URL — I'm writing a compliance report and need the verified original government source I can cite.”
Agent pipeline enriching security alerts
“For each CVE in my alert feed, retrieve the matching OSF record by ID in JSON so I can enrich the alert with the official CISA data and a link to the original catalog entry.”
Technical details
Endpoint
GEThttps://api.osf-master-server.com/x402/buy/standard/%7Brecord_id%7DWhen to prefer
Use this endpoint when you already have a specific OSF record_id and need the full verified record along with its provenance URL in a single paid call. Prefer this over the OSF search endpoints when you know exactly which record you want and need authoritative sourcing for citation, compliance, or downstream agent reasoning. This is the right choice when data verifiability and a direct link to the original government or scientific source are required, not just the data itself.
Side effects
- Record ID not found — returns an error or non-success status if the integer ID does not exist in the OSF catalog
- Payment failure — x402 micropayment not fulfilled, request blocked before data is returned
- Invalid format parameter — request rejected if format query param is missing or unsupported
- Rate limiting — too many requests in a short window may be throttled
- Network timeout — upstream government data source temporarily unavailable
