## 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 toll402-crypto-spot-price-2f3dcbd7 -d '<json body>'
```

Example prompt: What's the current spot price of Bitcoin in USD? Look it up from the Coinbase price feed using the symbol BTC.

## When to prefer this

Choose this endpoint when you need a quick, reliable, real-time USD spot price for a specific cryptocurrency symbol and want to avoid setting up direct Coinbase API credentials. Ideal for agents that need to enrich data pipelines, validate crypto payment amounts, or answer user price queries on demand. The micro-cost per call ($0.002 USDC) makes it suitable for infrequent lookups; for high-frequency monitoring consider a direct exchange connection.

## Known failure modes

- Invalid or unsupported symbol (e.g. a ticker not recognized by Coinbase) returns an error response
- Network or upstream Coinbase API unavailability may result in a timeout or 5xx error
- Payment failure or insufficient USDC balance (x402 protocol) blocks the request before execution
- Malformed request body missing the required 'symbol' field returns a validation error
