# Bill Bounty Check

> Bill Bounty Check is a paid API for AI agents from bill.olympusai.duckdns.org, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15).

Analyzes a GitHub repository (and optionally a specific issue) to determine whether a posted bounty is likely to actually pay out, using deterministic public GitHub signals.

## 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 bill-bounty-check-8b4cdb6d
```

Example prompt: Before I start coding, can you check whether the bounty on github.com/owner/repo issue #42 actually looks like it pays — I want to see merge history, red flags, and a verdict on whether it's worth my time.

## When to prefer this

Use this endpoint when an agent or developer needs a fast, deterministic, no-hallucination signal on whether a GitHub bounty is likely to pay before investing coding effort. Prefer this over manual GitHub browsing or general-purpose LLM reasoning when you need structured red/green flags and a machine-readable verdict backed by real merge history data.

## Known failure modes

- Invalid or non-existent GitHub repo returns an error
- Private repositories cannot be analyzed (public data only)
- Issue number not found on the specified repo
- Rate limits on GitHub data fetching may delay or fail responses
- Repos with zero activity may return null for merge-speed metrics

## How this service works

Before you spend work on a GitHub bounty, check whether it looks like it actually pays. Deterministic, public GitHub data only: merge speed, payout evidence, trap and pile-up red flags, and a verdict.

## Output

Returns a JSON object with the repo name, optional issue number, a set of metrics (stars, last merge date, repo age in days, issue comment count, median hours to merge, merged PRs in last 30 closed), a verdict (e.g. 'avoid' or 'promising'), a list of red flags (e.g. 'no merged PRs among the last 30 closed'), and a list of green flags (e.g. 'reward is stated in USD or USDC').
