## 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 x402-crypto-apis-cryptocurrency-data-search-28d4f95a -d '<json body>'
```

Example prompt: Search the x402 crypto API for 'BTC' and return up to 5 results with price and market data.

## When to prefer this

Use this endpoint when you need cryptocurrency market data or coin lookup on a pay-per-call basis without a subscription, especially when integrating into an x402-compatible micropayment workflow. Prefer this over subscription-based crypto APIs when call volume is low or sporadic, and when USDC micropayment settlement is already part of your agent's payment infrastructure.

## Known failure modes

- Payment failure: insufficient USDC balance for the $0.068723 micropayment results in 402 Payment Required
- Invalid or unrecognized coin symbol returns empty or null data payload
- Missing required 'query' field returns a validation error
- Upstream cryptocurrency data provider outage may result in empty or error response
- Path parameter not matched to a valid sub-endpoint returns 404 or unexpected response
