## When to prefer this

Use this endpoint when you need to discover active US federal grant opportunities from Grants.gov, especially for nonprofits, researchers, or organizations seeking government funding. Prefer this over the sibling SAM.gov contracts endpoint when the user is looking for grants and funding opportunities rather than procurement contracts.

## Known failure modes

- No results found for overly specific or obscure search terms
- Payment failure if USDC balance is insufficient (x402 payment required)
- Rate limiting if too many requests are made in quick succession
- Grants.gov API downtime causing unavailable results
- Malformed query parameters returning empty or error responses
