Search US federal biomedical research grants via NIH RePORTER. Filter by term (free-text over project title, terms, and abstract), org (funded institution name), pi (principal-investigator name), and/or fiscalYear; page with limit (1-50) and offset. Returns each award with project number, title, fiscal year, award amount (USD), contact PI, organization (name, city, state, country, department), funding agency/institute, and project start/end dates — newest fiscal year first, with a total match count. Data: NIH RePORTER, free and public-domain. Fresh post-training award data agents cannot know; pair with /api/research/org (ROR) and /api/research/author (ORCID). Use for funding landscape research, competitor/lab tracking, and grant-opportunity context.
/api/research/fundingPAYMENT-SIGNATURE.The funding API is a pay-per-call research endpoint built for AI agents and autonomous software. Search US federal biomedical research grants via NIH RePORTER.
There is no signup and no API key. An agent (or any HTTP client) hits the endpoint, receives an x402 "402 Payment Required" challenge, signs a sub-cent USDC payment on Base or Solana, and retries — the data comes back on the paid request. That makes it a drop-in funding data source for an agent tool-use loop, an MCP host, or a backend that needs research data on demand without onboarding to yet another vendor portal.
