## 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 greater-good-grants-search-6c557f04
```

Example prompt: Can you search for up to 10 currently posted federal grants related to affordable housing and community development, filtering to open opportunities only?

## When to prefer this

Choose this endpoint when you need to search U.S. grant opportunities by mission topic or eligibility with evidence-backed sourcing, especially when you want direct links to official grants.gov pages and deadline countdowns. Prefer it over general web search for grants because it returns structured, machine-readable data with official URLs and status filters. It is particularly well-suited for nonprofits and researchers doing programmatic grant prospecting within a specific funding domain.

## Known failure modes

- No results returned when keyword is too narrow or misspelled — try broader or synonymous terms
- rows parameter must be between 1 and 25; values outside this range will be rejected
- Invalid status enum values (e.g. 'open' instead of 'posted') may return errors or empty results
- Eligibility codes that don't match any grants will silently return zero results
- Service may return stale data if upstream grants.gov sync is delayed

## How this service works

News for the love of humanity. Evidence-backed U.S. reporting with sources, dates, and room for uncertainty.

## Output

Returns a JSON object with a totalMatches count and an array of grant opportunities, each containing a unique grant ID, title, a direct link to the official grants.gov detail page, and the number of days remaining until the deadline.
