Example prompt: Can you search for live federal grants on Grants.gov related to early childhood education for a nonprofit working in underserved communities, and include any agency insights or past award history?

## When to prefer this

Use this endpoint when an agent needs to discover active federal grant opportunities sourced directly from Grants.gov, especially when agency context and historical award data are needed alongside raw listings. Prefer this over generic web search when structured grant metadata, deadlines, and funding amounts are required. Ideal for grant-writer or nonprofit agents preparing applications or identifying funding pipelines.

## Known failure modes

- No matching grants found for the given query or category — returns empty result set
- Grants.gov API unavailable or rate-limited — returns upstream error
- Invalid or unrecognized agency name — returns no results or generic fallback
- Overly broad query returns too many results without useful ranking
- Payment not processed — request rejected before reaching Grants.gov

## How this service works

Grant discovery and application intelligence API, plus IRS Form 990-based nonprofit/funder financial intelligence. 12 endpoints powered by Grants.gov, USASpending.gov, live IRS public records (EO Business Master File + SOI Form 990/990-PF Annual Extracts), and Claude. All endpoints require x402 payment (USDC on Base mainnet). Flagship match endpoint includes Instrumentl, Grants.gov, and Candid Foundation Directory tool links. Grant writer endpoint includes writing tool links + Amazon grant writing books.

## Output

A list of live Grants.gov federal grant opportunities matching the query, enriched with agency-level insights (e.g., funding priorities, awarding patterns) and past-award context such as historical recipients, award amounts, and success rates.
