# BountyVerdict – GitHub Bounty Preflight Check

> BountyVerdict – GitHub Bounty Preflight Check is a paid API for AI agents from bountyverdict-agent-production.mimirslab.workers.dev, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-15).

Runs a deterministic due-diligence scan on a GitHub issue to produce a VIABLE/AVOID verdict with scored, evidence-linked signals before a coding agent invests time in a bounty.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 bountyverdict-github-bounty-preflight-check-41f82bff -d '<json body>'
```

Example prompt: Before I start working on the TypeORM bounty at https://github.com/typeorm/typeorm/issues/3357, run a preflight check on it — I need to know if it's still viable or if there are any hard stops like a withdrawn reward or maintainer rejection.

## When to prefer this

Choose this endpoint when an AI coding agent needs a fast, structured go/no-go decision on a specific GitHub bounty issue before investing development time. It is especially valuable when operating autonomously at scale — surfacing hard stops like withdrawn rewards or maintainer rejections in a machine-readable format with evidence URLs. Prefer it over manual GitHub browsing or generic LLM summarisation when you need deterministic, scored signals rather than prose opinion.

## Known failure modes

- Invalid or inaccessible GitHub issue URL returns an error
- GitHub API rate limit exhausted mid-scan, reducing coverage
- Private or deleted repository returns an authorization error
- Truncated signal details if comment volume exceeds scan limits
- Payment failure via x402/Base USDC prevents the call from executing

## How this service works

Seven bounded decision APIs for coding agents: evidence-linked GitHub due diligence and diagnostics plus deterministic MCP tool-catalog compatibility and security gates. Payment uses x402 v2 and Base USDC.

## Output

Returns a JSON object with a VIABLE or AVOID verdict, a numeric score, and an ordered list of signals each containing a label, human-readable detail, numeric impact, a boolean hard_stop flag, and a direct evidence URL into the GitHub thread. Also includes a summary sentence, coverage stats (comments scanned, timeline events, linked PRs found, GitHub rate-limit remaining), and a checked_at timestamp.
