## 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 v0-x402-endpoint-vercel-app-41c10c99 -d '<json body>'
```

Example prompt: What's the real-time price of BTC right now? Use the x402 crypto price feed and charge my account the micropayment.

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call real-time spot price for a major cryptocurrency (BTC, ETH, SOL, etc.) and want a low-cost micropayment model via x402 without a subscription. Ideal for agents that need occasional on-demand price checks rather than a streaming feed.

## Known failure modes

- Unknown or unsupported symbol returns an error or empty result
- Payment failure (insufficient USDC balance) blocks the request
- Network timeout if the upstream price feed is unavailable
- Malformed request body missing the symbol field returns a 400 error
