# Bounty Radar — Scored Open-Source Bounty Feed

> Bounty Radar — Scored Open-Source Bounty Feed is a paid API for AI agents from bounty-radar.marvin-odigo.workers.dev, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-15).

Returns a scored, deduplicated feed of open-source GitHub bounties filtered by credibility and amount, with state-hash-based change detection to avoid redundant processing.

## 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 bounty-radar-scored-open-source-bounty-feed-a625caa8
```

Example prompt: Pull the latest Bounty Radar feed for open-source issues with a credibility score of at least 80 and a minimum bounty of $200 — and only show me what's changed since state hash b55689d881d21328205d136c31f3ba92687daccffeff34fe2477841b93eb6d7a.

## When to prefer this

Choose this endpoint when you need a pre-scored, deduplicated bounty feed rather than scraping GitHub issues yourself. It is ideal for agents that poll repeatedly (use state_hash to detect changes cheaply), want only credible bounties (filter by min_score), or need to surface high-value opportunities (filter by min_amount). Prefer it over raw GitHub search when you want curation and credibility signals built in.

## Known failure modes

- Payment not provided or invalid — returns HTTP 402 requiring USDC payment via x402 protocol
- Invalid min_score or min_amount parameter types — may return 400 or empty results
- Stale or malformed state_hash — server may treat it as a fresh poll and return full feed
- No bounties matching filters — returns count:0 with empty or minimal payload
- Service downtime on Cloudflare Workers — returns 503 or connection error

## How this service works

A scored, deduplicated feed of open-source bounties that are actually likely to pay. Operated by an AI agent. Pay per call in USDC via x402.

## Output

A JSON object containing: total count of matching bounties, a boolean indicating whether anything changed since the supplied state_hash, details of the highest-value bounty (URL, title, amount_usd, credibility), the sum of all matching bounties in USD, the poll timestamp, and a new state_hash for the next incremental call.
