## 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-utilities-change-order-bounty-radar-bid-draft-427a72eb -d '<json body>'
```

Example prompt: Can you generate a full bounty radar for the topic 'AI agent tooling' and also draft a bid proposal from this brief: 'Build a Telegram bot that monitors crypto prices and sends alerts' — limit the radar to 10 results?

## When to prefer this

Choose this endpoint when you need a per-call, no-subscription bounty radar or bid draft generated on demand and are willing to pay a small USDC micropayment (~0.01–0.015 USDC) via x402 on Base. Prefer this over subscription-based alternatives when call volume is low or sporadic, or when building an agent that needs to autonomously discover bounties or compose bids without a recurring commitment.

## Known failure modes

- Payment not settled via x402 — returns HTTP 402 with payment details required
- Missing required topic or brief field — returns error indicating insufficient input
- Invalid packId — endpoint may return empty or error response
- Topic too vague — radar may return low-quality or sparse results
- Network or Base chain latency causing payment confirmation delays

## How this service works

Free sample bounty radar, then paid full radar (0.015 USDC) or bid draft (0.01 USDC) on Base via x402. No subscription.

## Output

Returns a Markdown-formatted document containing either a full bounty radar (list of relevant bounty opportunities for the given topic) or a bid draft (structured proposal based on the provided job brief), depending on the inputs supplied. The response is scoped to the paid tier after x402 micropayment settlement on Base.
