How this service works
Sample any single record in the OSF catalog for $0.001: the full JSON payload plus a provenance URL to the authoritative primary source. A low cost way for an autonomous agent to try the data before buying at the standard per record or search price. One verified record per call keyed by record_id from the free catalog, across 80 sources of US government and scientific data. Fair use daily cap per wallet.
Output
A JSON object containing the full record data payload, the record_id, a provenance_url pointing to the authoritative primary source, the data source name, data_type, and a status field. This lets you verify the content and quality of a specific OSF catalog record before committing to larger queries.
Example use cases
Example prompt
“Pull the OSF catalog sample record with ID 48291 in JSON format so I can see the full data payload and its provenance URL before I decide whether to run a full search.”
Technical details
Endpoint
GEThttps://api.osf-master-server.com/x402/sample/:record_idWhen to prefer
Use this endpoint when you want to inspect or verify a specific known record from the OSF catalog before committing to a full search or bulk purchase. It is ideal for due diligence on data quality, checking provenance, or previewing a single record type cheaply. Prefer this over the search endpoints when you already have a record_id from the free catalog and just need the full payload.
Side effects
- Record ID not found in catalog — returns 404 or error status
- Daily fair-use cap per wallet exceeded — request blocked until reset
- Insufficient USDC balance for $0.001 payment — payment fails
- Invalid or missing format query parameter — returns 400 validation error
- Record ID is not a valid integer — schema validation failure
