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 containing a result status (e.g. MATCHES_FOUND), an array of matched records each with a source database name (e.g. CLINICALTRIALS), a numeric record ID, a standardized identifier (e.g. NCT number), and a name or title for the study or record, plus a total match count.
Example use cases
Clinical trial discovery for a drug
“Find all public clinical trials on OSF involving semaglutide — I want the NCT IDs, study titles, and which registry each one came from.”
NPI provider record lookup
“Look up the verified public record for NPI number 1234567890 on OSF and tell me the provider name and any associated data.”
Condition-based trial research
“Search OSF's provenance-stamped healthcare data for clinical trials related to advanced solid tumors — give me the trial identifiers and sponsors.”
Technical details
Endpoint
GEThttps://api.osf-master-server.com/x402/healthcare/records/%7Bquery%7DWhen to prefer
Choose this endpoint when you need verifiable, provenance-stamped healthcare and clinical data from authoritative US government sources (ClinicalTrials.gov, NPI registry) and require source attribution for each record. It is ideal for agents operating in regulated or research contexts where data lineage matters, and when micropayment-per-record pricing is preferable to a subscription. Prefer this over general web search when you need structured, machine-readable healthcare records with traceable provenance.
Side effects
- No matches found for the query keyword — result status indicates no records
- Invalid or malformed query string causes a 400-level error
- Payment not completed or insufficient USDC balance triggers an x402 payment required response
- Query too vague returns too many or irrelevant matches
- NPI or NCT identifier not found in the indexed dataset
