## 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-hub-crypto-list-3adaafc2 -d '<json body>'
```

Example prompt: Search the crypto list for all tokens matching 'ethereum' and show me what comes back.

## When to prefer this

Use this endpoint when you need to search or list cryptocurrencies by a keyword or name and are operating in an x402 micropayment environment on Base. Prefer this over free alternatives when you need pay-per-call access without API key registration, or when building agents that autonomously pay for data access.

## Known failure modes

- Missing or empty 'query' field returns a validation error
- Query too vague or unrecognized returns empty or minimal results
- Payment failure (insufficient USDC balance or x402 handshake error) results in 402 response
- Upstream API unavailability causes 5xx errors
- Malformed query string may return unexpected or empty data
