Technical details
Endpoint
GEThttps://trinity-throw-thursday-gravity.trycloudflare.com/x402/grant-matchWhen to prefer
Use this endpoint when you need to quickly surface relevant active federal grant opportunities from Grants.gov without manually searching the portal. It is ideal for nonprofit administrators, grant writers, research offices, and small business development agents who need to match a descriptive applicant profile to live funding opportunities. Prefer this over a generic web search when you want structured, source-linked grant results tied to Grants.gov's authoritative data.
Side effects
- No matches found if the profile is too narrow or niche — returns empty result set
- Grants.gov data may lag real-time postings if the underlying index is not freshly synced
- Invalid or overly long profile string may be rejected with a validation error
- Agency filter typo or unrecognized value may return zero results
- Limit parameter exceeding 5 will be rejected by schema validation
