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.
Example use cases
Screening a bounty before starting work
“Before I invest time on this, can you check if the bounty at https://github.com/owner/repo/issues/452 is legitimate — real money, open for grabs, and not already assigned to someone?”
Filtering a list of discovered bounties
“I've got a GitHub issue reference uniswap-labs/v4-core#210 — run a claimability check on it and tell me the verdict, the dollar amount, and any red flags like competing pull requests or test tokens.”
Automated bounty pipeline triage
“As part of my bounty-hunting workflow, check paraloom-labs/paraloom-core#839 and let me know if BountyCheck thinks it's real money, what signals it flagged, and whether the repo looks active enough to bother with.”
Technical details
Endpoint
GEThttps://bountycheck.vercel.app/v1/check?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
