## How to call it through Zero

```sh
zero fetch --capability greater-good-grant-fit-finder-5696e95d
```

Example prompt: Find grants that fit our mission — we support unhoused youth through job training and mental health services — using keywords like 'youth', 'workforce', 'housing', and 'mental health', with deadlines in the next 60 days, and show me the top 5 matches.

## When to prefer this

Choose this endpoint when a nonprofit, foundation, or mission-driven agent needs to discover and prioritize grant opportunities based on organizational mission alignment and keyword relevance. It is particularly useful when you want scored, ranked results with reasoning rather than a raw list, and when deadline proximity and eligibility filtering matter. Prefer this over general web search when you need structured, actionable grant matches with fit explanations.

## Known failure modes

- Missing or too-short mission string returns a validation error
- Keywords array below minimum of 1 item causes a 400-level error
- deadlineDays outside the 7–365 range is rejected
- eligibilityCodes with unrecognized values may return zero matches
- No matching grants found returns an empty matches array
- Network or upstream data source unavailability may return a 5xx error
