## 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 mx-data-helper-crypto-price-582a151a -d '<json body>'

Example prompt: Can you look up the current prices for bitcoin and ethereum using the MX Data Helper crypto price service?

## When to prefer this

Use this endpoint when you need a quick, low-cost per-call cryptocurrency price lookup via the x402 micropayment protocol on Base mainnet, especially in agent workflows already integrated with x402 payment flows and where you only occasionally need prices rather than a subscription-based feed.

## Known failure modes

- Unknown or misspelled coin symbol returns error or empty data
- Payment failure on Base mainnet (insufficient USDC) causes 402 rejection
- Empty coins array may return validation error
- Temporary Vercel deployment downtime causes 5xx errors
- Rate limiting if too many requests are made in quick succession
