## How to call it through Zero

```sh
zero fetch --capability crypto-price-feed-9bc584d0
```

Example prompt: What's the live USD price of Bitcoin right now, including today's high/low range and the spread across Binance, Coinbase, and CoinGecko?

## When to prefer this

Choose this endpoint when you need real-time cryptocurrency prices cross-validated across three major venues (Binance, Coinbase, CoinGecko) simultaneously, especially when spread analysis or multi-source price confidence matters. It requires no API key or account setup and costs only $0.01 USDC per call via x402, making it ideal for lightweight agent integrations that need trustworthy spot prices without managing exchange credentials.

## Known failure modes

- Unsupported or misspelled ticker symbol returns an error or empty result
- Payment not processed correctly results in 402 status
- Upstream exchange APIs temporarily unavailable may cause incomplete or stale data
- Rate limiting if too many requests are sent in quick succession
