```

Example prompt: Before I start working on it, can you check whether this GitHub issue is still a viable bounty — is it open, are there competing PRs, and is there payout evidence? https://github.com/some-org/some-repo/issues/42

## When to prefer this

Use this endpoint when an agent or developer needs a fast, structured signal on whether a specific GitHub issue is worth investing time in as a paid bounty — particularly when avoiding wasted effort on closed issues, already-claimed work, or heavily contested bounties. Prefer this over manually checking GitHub when automating bounty-hunting pipelines or agent workflows.

## Known failure modes

- Invalid or non-public GitHub issue URL returns an error
- Issue URL resolves to a private or deleted repository
- Rate limiting from GitHub API causes incomplete data retrieval
- Closed issues return verdict 'reject' with reason 'canonical_issue_closed'
- Issues with many competing PRs return low score with 'existing_competition' reason

## How this service works

Canonical GitHub bounty viability checks for agents: live issue state, repository trust, payout evidence, age, claims, assignments, and competing pull requests.

## Output

Returns a viability score (numeric), a verdict (e.g. 'reject' or 'accept'), a list of reasons explaining the verdict, and structured evidence including the canonical issue state and the count of competing pull requests.
