## 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-utilities-hub-crypto-utilities-endpoint-0fc11ac5 -d '<json body>'
```

Example prompt: Run the x402 Utilities Hub crypto utility endpoint — it costs $0.01 USDC per call on Base — and pass in my query parameters to get the result back.

## When to prefer this

Choose this endpoint when you need a cheap ($0.01 USDC) pay-per-call crypto utility accessible via the x402 protocol on Base, and your agent is already set up for x402 micropayments. It is best suited for lightweight, on-demand crypto computations or lookups that don't justify a subscription API. Avoid if you need high-volume calls (cost adds up), detailed documentation of outputs, or are not set up for x402 payment flows.

## Known failure modes

- Payment failure: insufficient USDC balance or x402 payment not processed — returns 402 Payment Required
- Invalid queryParams: missing required fields in the queryParams object — returns 400 Bad Request
- Rate limiting or worker timeout: Cloudflare Worker may throttle or timeout — returns 503 or 524
- Unknown crypto utility parameters: queryParams not recognized by the endpoint — returns error or empty example object
- Network issues with Base blockchain settlement — payment may not confirm, causing request rejection
