## How to call it through Zero

```sh
zero fetch --capability greater-good-grants-detail-lookup-2d007754
```

Example prompt: Can you pull up the full details for grant opportunity 363537 — I need the award ceiling, eligibility rules, and the official grants.gov link?

## When to prefer this

Use this endpoint when you have a specific grants.gov opportunity ID and need structured detail data — award ceiling, eligibility text, and official URL — without scraping grants.gov directly. It is cheaper and faster than a full-text search and ideal for downstream filtering, eligibility matching, or populating grant-writing workflows.

## Known failure modes

- Invalid or non-existent opportunityId returns an error or empty result
- opportunityId below minimum value of 1 rejected by schema validation
- Grant opportunity may have expired or been removed from grants.gov, returning stale or missing data
- Network or upstream grants.gov outage may cause retrieval failure
