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), a list of matching spending records each with a title (recipient/award name), awarding agency, dollar amount, data source (e.g. USASpending), a record ID, and a provenance URL linking to the official government source record.
Example use cases
Vendor due diligence for government contracts
“Look up whether Mono Machines LLC has received any federal government contracts and tell me which agencies awarded them money and how much.”
Defense program spending research
“Search government spending records for awards related to 'maritime grant' — I want to know which agencies are funding maritime programs and what the dollar amounts look like.”
NAICS code contract discovery
“Find me federal spending records for contracts filed under the radar or electronic warfare space — I'm trying to understand the competitive landscape for navy tech vendors.”
Technical details
Endpoint
GEThttps://api.osf-master-server.com/x402/gov/spending/%7Bquery%7DWhen to prefer
Choose this endpoint when you need verifiable, provenance-stamped federal government spending data with a direct link to the official source record. Prefer it over generic web search when auditability and source attribution matter — e.g. for compliance research, vendor due diligence, or journalism. It is especially useful for AI agents that need to cite authoritative public records rather than scraped or aggregated data.
Side effects
- No matches found for keyword — returns empty matches array
- Ambiguous or overly broad keyword returns too many low-relevance results
- Micropayment fails or x402 authorization is rejected — no data returned
- Query string malformed or missing — 400 error
- Source system (USASpending) temporarily unavailable — upstream timeout
