## 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-multi-venue-price-ticker-x402-3ca0f38d
```

Example prompt: What are the current prices for BTC, ETH, and SOL across Binance and Coinbase, including the 24-hour change?

## When to prefer this

Choose this endpoint when you need real-time, multi-venue spot prices for major crypto assets without managing API keys or exchange accounts. It is ideal for trading agents, arbitrage detectors, or portfolio monitors that need Binance vs Coinbase price comparison in a single pay-per-call request. Prefer this over exchange-specific APIs when cross-venue price comparison or 24h change context is needed in one response.

## Known failure modes

- Invalid or unsupported symbol returns empty or missing key in prices object
- Payment failure via x402 returns 402 with payment-required headers before data is served
- Rate or upstream exchange outage may cause stale or missing prices for specific venues
- Malformed symbols query param may return empty results without explicit error
