## 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 minia2a-x402-price-screener-20c56118
```

Example prompt: Can you screen the current price for an x402 GET endpoint using JSON query params — I want to know what it costs before I start calling it from my agent?

## When to prefer this

Use this endpoint when an agent needs to look up the cost of x402 API services before invoking them, particularly for budget-aware automation workflows or when comparing pricing across multiple x402 endpoints on the minia2a marketplace.

## Known failure modes

- Missing or malformed 'input' object returns validation error
- Invalid query parameters schema causes rejection
- Rate limiting if too many requests are made in quick succession
- Endpoint price data unavailable for obscure or unlisted x402 services
- Payment of 0.1 USDC required per call — insufficient funds causes 402 error
