# BountySignal — Source-Verified Developer Bounties

> BountySignal — Source-Verified Developer Bounties is a paid API for AI agents from fortyeight-rescue.jaeber2se.chatgpt.site, paid per call via x402, $5/call, status unknown (last checked 2026-09-14).

Analyzes a GitHub issue to verify its open state, reward amount, competition level, payout restrictions, and fit before a developer commits time to it.

## 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 bountysignal-source-verified-developer-bounties-74480319 -d '<json body>'
```

Example prompt: Before I start coding, can you run a BountySignal check on this GitHub issue — https://github.com/owner/repo/issues/42 — I know Python and TypeScript and can spend up to 20 hours on it?

## When to prefer this

Choose BountySignal when a developer or agent needs to make a go/no-go decision on a specific GitHub bounty issue before investing time — especially when the reward amount, payout mechanism, issue state, or competition level are uncertain. It is more useful than a raw GitHub API call because it aggregates reward verification, competition sensing, fit scoring, and a claim draft into a single decision-ready report. Prefer it over manual issue inspection when operating at scale or automating bounty-hunting workflows.

## Known failure modes

- Invalid or non-existent GitHub issue URL returns validation error
- Issue URL not matching required pattern (must be a numbered issue, not a PR or discussion) returns schema rejection
- Private or restricted GitHub repository may result in inability to fetch issue state
- Network timeout or GitHub API unavailability may cause partial or failed report
- Bounty reward not machine-readable from issue body results in null or estimated reward fields
- Payment failure (insufficient USDC balance) blocks the call entirely

## How this service works

Live paid-issue radar that checks source state, reward state, competition, and payout restrictions before you start.

## Output

Returns a structured JSON report including: issue open/closed state and URL, stated reward in USD, competition level and number of open claims, a scored recommendation verdict (e.g. 'verify_first', 'proceed', 'avoid'), a step-by-step execution plan, a ready-to-post claim draft comment, observed payout rails, a scope checklist, optional buyer profile fit score, and a SHA-256 checksum of the core report for integrity verification.
