## 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 bountycheck-github-bounty-claimability-checker-d092c8eb
```

Example prompt: Can you check whether the bounty on https://github.com/paraloom-labs/paraloom-core/issues/839 is actually claimable and worth working on — like, is it real money or just testnet tokens, and are there already competing PRs?

## When to prefer this

Use BountyCheck when an AI agent or bounty-hunting workflow needs a fast, structured signal on whether a specific GitHub issue's bounty is worth pursuing — particularly when you need to distinguish real-money bounties from testnet/devnet fakes, check for competing PRs, or confirm the issue is unassigned. It is purpose-built for this narrow validation task and cheaper than building custom GitHub scraping logic.

## Known failure modes

- Missing or malformed 'url' / 'issue' query parameter — returns an error indicating required input
- GitHub issue not found or private repo — may return error or empty result
- Issue exists but has no bounty signals — verdict may be 'not_a_bounty' or similar
- Rate limiting or payment failure (x402 USDC on Base not fulfilled) — returns 402 Payment Required
- GitHub API rate limits on the backend — may cause delayed or failed responses

## How this service works

Pay-per-call (x402, USDC on Base) API that tells bounty-hunting agents which open-source GitHub bounties are actually claimable.

## Output

A JSON object containing: the canonical issue URL and reference, the issue title, a verdict string (e.g. 'not_real_money', 'claimable', etc.), a USD bounty amount, a list of human-readable reasons supporting the verdict, and a signals object with fields like state, assignees, competing_prs, repo_stars, test_money flag, comment count, distinct commenters, payout_address_comments, rewarded_marker, start_restricted, repo_archived, and repo_created_at.
