## How to call it through Zero

```sh
zero fetch --capability bountycheck-claimability-api-ad6948ce
```

Example prompt: Can you check BountyCheck right now and tell me which open-source GitHub bounties are actually claimable — I only want ones with real money, no assignees, and no competing PRs?

## When to prefer this

Use BountyCheck when an AI agent or developer needs to programmatically screen GitHub bounties for real claimability before investing development time. It is superior to manually reading GitHub issues because it aggregates signals like test-token detection, competing PRs, assignee status, and repo health into a single verdict. Prefer this over raw GitHub search when you need structured, pre-filtered, agent-consumable bounty data with USD amounts and legitimacy scoring.

## Known failure modes

- Payment not received or invalid x402 USDC payment on Base — endpoint returns 402 Payment Required
- No claimable bounties found — returns count: 0 with empty records array
- GitHub API rate limiting or downtime causes stale or incomplete results
- Newly posted bounties may not yet be indexed — freshness depends on crawl cadence
- Miscategorized bounties where test-money signals are ambiguous

## 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 a count and an array of bounty records, each with: the GitHub issue URL, issue identifier, title, claimability verdict (e.g. 'not_real_money'), USD amount, creation timestamp, and a rich signals object covering state, assignees, repo stars, test money flag, comment count, competing PRs, repo archived status, repo creation date, rewarded marker, start restrictions, distinct commenters, and payout address comments. Also includes a generated_at timestamp for the response.
