## How to call it through Zero

```sh
zero fetch --capability bounty-claimability-api-3595da60
```

Example prompt: Before I start working on this GitHub issue, can you audit it for bounty claimability and tell me the risk score, verdict, and whether the $100 payout is realistic? Here's the URL: https://github.com/some-org/some-repo/issues/42

## When to prefer this

Use this endpoint when an agent or user needs structured, scored due diligence on a specific GitHub bounty before committing development time — especially when payout legitimacy, claimability conditions, or risk factors are unclear. Prefer this over manual inspection when speed and a consistent scoring rubric matter.

## Known failure modes

- Invalid or non-public GitHub issue URL returns an error
- Issue has no bounty label or reward information, resulting in low score or null reward
- GitHub rate limits or access restrictions block the audit
- Bounty details are ambiguous, producing a low-confidence score with cautionary recommendation
- Network timeout from Vercel cold start
