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 with a result status (e.g. MATCHES_FOUND), an array of matching paper records each containing DOI, title, publication year, venue, data source, and internal record ID, plus a total match count.
Example use cases
Literature review for AI research
“Find me academic papers on transformer attention mechanisms — I need the DOIs, publication years, and venues so I can put together a reading list.”
Verifying a paper citation
“I have a DOI — 10.5555/3295222.3295349 — can you look it up on OSF and confirm the title, authors, and where it was published?”
Discovering recent climate science papers
“Search for peer-reviewed research papers on ocean acidification and coral reefs and give me a list of matches with their provenance details.”
Technical details
Endpoint
GEThttps://api.osf-master-server.com/x402/research/papers/%7Bquery%7DWhen to prefer
Choose this endpoint when you need provenance-stamped, verifiable bibliographic metadata for academic papers and are willing to pay per record via x402 micropayments. Prefer this over free academic search APIs when auditability and provenance are important, or when operating as an autonomous agent that can programmatically settle $0.05 USDC payments on Base. Best for agents building citation lists, conducting literature reviews, or verifying academic claims.
Side effects
- No matches found for obscure or misspelled query terms
- DOI format not recognized if malformed
- Rate limiting or payment failure if x402 micropayment on Base is not processed
- Empty results for very niche or newly published papers not yet indexed
- Query too vague returns low-relevance results
