## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability grants-gov-federal-grant-opportunity-search-3bcdad0e
```

Example prompt: Search Grants.gov for federal grant opportunities related to 'affordable housing' and show me up to 8 listings including which agency is offering them, the opportunity number, open and close dates, and their CFDA numbers.

## When to prefer this

Choose this endpoint when you need to discover active or forecasted US federal grant opportunities by topic keyword, especially when you need structured data including CFDA numbers, agency names, and open/close dates. It surfaces opportunity listings only — not award decisions or recipient data — making it ideal for grant prospecting workflows. Prefer this over manual Grants.gov searches when integrating grant discovery into automated research or funding pipelines.

## Known failure modes

- Keyword too short (under 3 characters) or too long (over 60 characters) returns a validation error
- Grants.gov search2 API upstream outage causes failure or empty results
- No matching opportunities found returns totalHits of 0 and an empty opportunities array
- Limit parameter out of range (outside 1-10) may return default of 5 or an error
- Results reflect Grants.gov index state at crawl time and may lag real-time status changes

## How this service works

Pay-per-call company registry, government, legal and B2B data tools for AI agents, from official registers and public sources. Payment: x402, USDC on Base, Solana, Arc, Polygon, Arbitrum, Monad, World Chain, Optimism, Avalanche, Celo or Stellar, or RLUSD/XRP on the XRP Ledger. No signup, no API key; a failed call is not charged.
