How this service works
Screen one Grants.gov opportunity for applicant-type, deadline, budget, and topical-fit conflicts using the current official API record.
Output
A structured eligibility brief covering: whether the applicant type matches, any deadline feasibility conflicts given required preparation time, whether the project budget falls within the grant's stated range, and an assessment of topical alignment between the applicant profile and the opportunity's stated objectives — all derived from the live Grants.gov API record at call time.
Example use cases
Nonprofit eligibility pre-check
“Check Grants.gov opportunity 348920 for us — we're a small rural healthcare nonprofit, budget around $500,000, and we need 30 days minimum to apply. Flag any eligibility conflicts or deadline issues.”
University research grant screening
“Screen Grants.gov opportunity 361045 for a public university research team working on climate adaptation. Our project budget is $750,000 and we need at least 45 days to submit. Does it fit?”
Startup applicant-type conflict check
“We're a for-profit tech startup applying to Grants.gov opportunity 372100 with a $150,000 budget and 14 days to apply — can you tell me if there are any applicant-type or topical conflicts we should know about before we start?”
Technical details
Endpoint
GEThttps://trinity-throw-thursday-gravity.trycloudflare.com/x402/grant-eligibilityWhen to prefer
Use this endpoint when you need a rapid, structured eligibility pre-screen of a specific Grants.gov opportunity before committing resources to a full proposal. It is especially valuable when you have the opportunity ID in hand and want to check applicant-type, deadline, budget, and topical fit in a single call. Prefer this over manual Grants.gov browsing when automating grant discovery pipelines or building decision support for grant writers. Not suited for bulk batch screening across many opportunities simultaneously, or for grant discovery (finding opportunities — it screens a known one).
Side effects
- Invalid or non-existent opportunity_id returns an error or empty record
- Expired or closed grants may return no active record
- opportunity_id must be numeric (up to 12 digits); non-numeric values are rejected by schema
- Missing required query params (opportunity_id or profile) result in a 400-level error
- Grants.gov API downtime may cause upstream fetch failure
- Budget mismatch edge cases (e.g. grants with no stated maximum) may yield incomplete budget assessment
