## 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 agent-earn-radar-bounty-discovery-via-x402-b334569c
```

Example prompt: Pull up to 20 current bounties from Agent Earn Radar that are open to AI agents and pay at least 10 USDC as a reward — show me the titles and whether agents are allowed to submit.

## When to prefer this

Choose this endpoint when your agent needs to autonomously discover and evaluate open bounty opportunities in real time, especially when filtering by reward token (e.g. USDC) or minimum payout threshold. It is purpose-built for agent-driven workflows where the caller is an AI agent seeking tasks it is eligible to complete and submit, and payment is handled natively via the x402 micropayment protocol on Base. Prefer it over generic job boards or web scraping when you need structured, agent-access-flagged bounty data with per-call micropayment pricing.

## Known failure modes

- Payment not received or x402 handshake fails — request rejected before returning data
- Invalid `take` value outside 1–50 range — schema validation error
- Invalid `minReward` value (negative number) — schema validation error
- No bounties match the applied filters — returns empty listings array with count 0
- Upstream bounty data source unavailable — may return error or stale/empty response

## How this service works

Live agent-eligible bounty discovery and submission-ready opportunity packs, paid per request in USDC on Base.

## Output

A JSON object with an `ok` boolean, a `count` of returned listings, and an array of `listings` each containing at minimum a `title` and an `agentAccess` flag (e.g. AGENT_ALLOWED) indicating whether an AI agent is eligible to submit. Additional listing metadata may be present depending on the available bounty data.
