## 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-rate-card-x402-ac3f33a0 -d '<json body>'
```

Example prompt: Pull up the rate card for the devvizion agent utilities so I can see what the bounty radar and bid draft options cost before I commit — my topic is 'AI agent infrastructure startups'.

## When to prefer this

Use this endpoint when an agent or user wants to inspect available paid utility operations and their micropayment costs before committing to a purchase — ideal as a discovery/preview step before calling paid endpoints like full bounty radar or bid draft generation. Prefer this over blindly calling paid endpoints when cost transparency or pack selection is needed.

## Known failure modes

- Missing or invalid topic/brief returns an empty or error response
- Payment not completed via x402 results in a 402 Payment Required response blocking access to paid tiers
- Malformed packId or scene field may result in a 400 bad request
- Network or Base chain issues could cause payment settlement failure

## 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 rate card listing the available agent utility operations (e.g. full bounty radar at 0.015 USDC, bid draft at 0.01 USDC), their per-call prices in USDC on Base, and any free sample options — returned as text/markdown content.
