```

Example prompt: Can you purchase and retrieve OSF public record number 4821 in JSON format so I can see the full data along with its provenance link back to the original government or scientific source?

## When to prefer this

Use this endpoint when you need a single verified public record from OSF with a direct provenance link back to a U.S. government or authoritative scientific source, particularly when auditability and source verification matter. Best suited for per-record, pay-as-you-go access at $0.05 per lookup without requiring a subscription.

## Known failure modes

- Invalid or non-existent record_id returns a 404 or error status
- Payment failure or insufficient USDC balance prevents record retrieval
- Missing required 'format' query parameter causes a validation error
- Network timeout or server unavailability returns a 5xx error
- Malformed record_id path parameter returns a 400 bad request

## How this service works

Purchase one verified OSF record ($0.05 tier) - returns the full record with a provenance URL back to its authoritative U.S. government or scientific primary source. OSF spans security, sanctions/compliance, SEC filings, economic, legal/regulatory, procurement, research, geospatial, and AI/ML data.

## Output

Returns a JSON object containing the record status, the record ID (integer), the full record data object, and a provenance_url pointing to the authoritative U.S. government or scientific primary source from which the record originates.
