## 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 crypto-data-node-x402-spot-price-lookup-c71f2ae9
```

Example prompt: What's the current spot price of BTC right now — pull it from Binance?

## When to prefer this

Use this endpoint when an AI agent needs a lightweight, pay-per-use real-time spot price for a major cryptocurrency from Binance, without setting up a subscription or API key — especially when x402 USDC micropayment is already supported in the agent stack.

## Known failure modes

- Invalid or unsupported symbol returns an error or empty response
- Payment not authorized or x402 micropayment fails — request blocked
- Binance data feed temporarily unavailable — stale or no price returned
- Malformed symbol path parameter causes a 400 or 404 error
