## 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

```

## When to prefer this

Choose this endpoint when you need real-time crypto spot prices for one or more pairs without API keys or account setup, paying only $0.001 USDC per call via x402. Ideal for agents that need instant, per-call pricing data for up to 25 pairs with Coinbase as the underlying source. Prefer this over subscription-based price feeds when usage is sporadic or micro-payment-native workflows are preferred.

## Known failure modes

- Invalid symbol format returns failed count > 0 for that pair
- Exceeding 25 symbols may result in truncation or error
- Payment failure via x402 (402 response) if USDC balance insufficient
- Network timeout on Cloudflare worker edge
- Unknown trading pairs return no price entry or are counted as failed
