## 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 current-usd-price-of-major-coin-by-name-34714394 -d '<json body>'
```

Example prompt: What's the current USD price of Ethereum right now? Look it up by its symbol ETH.

## When to prefer this

Use this endpoint when you need a real-time USD price for a major cryptocurrency by its ticker symbol, especially within an agentic or automated workflow that supports x402 pay-per-call micropayments. Prefer this over free alternatives when you need reliable, low-latency pricing with on-chain payment receipts for auditability. Best suited for single-coin spot price lookups rather than bulk or historical queries — use the sibling historical price endpoint for past prices.

## Known failure modes

- Unknown or unsupported coin symbol returns an error or empty price
- Payment failure via x402 protocol results in 402 Payment Required with no price data
- Network timeout or upstream price feed unavailability causes a failed response
- Malformed input (missing or invalid symbol field) may return a validation error
