## 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-paid-crypto-market-data-api-5aae8ad7
```

## When to prefer this

Choose this endpoint when you need real-time cryptocurrency market data and are already using or open to the x402 micropayment protocol. It is ideal for agents that need fresh crypto prices on-demand without a subscription, paying only $0.002 USDC per call. Prefer this over subscription-based data feeds for low-frequency, pay-per-use access patterns.

## Known failure modes

- Payment failure: insufficient USDC balance or wallet not configured for x402 payments — returns 402 Payment Required
- Invalid query parameters: unrecognized or malformed params return an error response
- Rate limiting or upstream data source unavailability causing 503 or timeout
- Network/Cloudflare Worker cold-start latency on first call
