## 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-kickoff-message-free-sample-paid-x402-754fa010 -d '<json body>'
```

Example prompt: Can you run a bounty radar on the topic 'AI agent tooling' — show me the free sample first, and if it looks good, go ahead and pay for the full radar results (up to 10 results)?

## When to prefer this

Use this endpoint when you need a low-commitment entry point to bounty radar or bid drafting — the free sample lets you evaluate relevance before spending USDC. Prefer this over subscription-based research tools when you want pay-per-use micropayment pricing on Base. Best for agents that need to scout freelance opportunities, draft bids, or generate project kickoff content on demand without a standing subscription.

## Known failure modes

- Payment not completed or rejected by x402 protocol — returns 402 Payment Required with payment instructions
- Invalid or missing topic/brief — may return empty or low-quality radar results
- packId not found — returns error if referenced pack does not exist
- Limit parameter too high — may result in truncated or slow responses
- Base network congestion — payment confirmation delayed, response stalled

## 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

A markdown-formatted kickoff message or bounty radar response. The free tier returns a sample preview; after x402 micropayment on Base (0.015 USDC for full radar, 0.01 USDC for bid draft), the full content is returned — either a structured list of bounty/opportunity radar results or a drafted bid document, depending on inputs provided.
