## 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-brief-e2c5352a
```

Example prompt: Find me current grant opportunities for our food security nonprofit — use keywords like 'hunger relief', 'food access', and 'community nutrition', look for grants with deadlines within the next 90 days, and filter for 501c3 eligibility.

## When to prefer this

Choose this endpoint when you need a curated, mission-matched brief of grant opportunities — especially when you have a clear mission statement, specific keywords, and a deadline window. It is particularly useful for nonprofits and foundations seeking actionable, filtered results rather than raw grant database dumps. Prefer this over generic grant search tools when you need urgency signals (deadlines within 30 days) and structured next-action guidance included in the response.

## Known failure modes

- Missing or too-short mission field (minLength 5) returns validation error
- Empty or oversized keywords array (must have 1–12 items) causes rejection
- deadlineDays outside 7–365 range returns parameter error
- No matching opportunities found returns empty opportunities array
- Network or upstream data source unavailability returns 5xx error
