## 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 alpha-vantage-crypto-exchange-rate-babe0d33 -d '<json body>'
```

Example prompt: What is Bitcoin's current exchange rate to USD — give me the live bid price, ask price, and the exact exchange rate?

## When to prefer this

Use this endpoint when you need a real-time spot exchange rate for a specific crypto-to-fiat or crypto-to-crypto pair, especially when bid/ask spread data is needed. Prefer this over historical time series endpoints when you need the current live price rather than historical prices. Best suited for single-pair lookups rather than bulk or historical queries.

## Known failure modes

- Unsupported target currency code causes a failed lookup
