## 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 coockies-ai-exchange-rate-api-52fa168d -d '<json body>'
```

Example prompt: What's the current exchange rate from US dollars to euros, and how much would 750 USD be in EUR?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call exchange rate lookup without committing to a monthly subscription to ExchangeRate-API directly. It is well-suited for low-frequency or sporadic currency conversion needs in automated agent workflows where cost should scale with usage rather than being a fixed overhead.

## Known failure modes

- Unsupported or invalid currency code returns an error or empty result
- Network timeout if the upstream ExchangeRate-API is unavailable
- Stale rate data if the upstream provider hasn't refreshed recently
- Payment failure on Base chain if USDC balance is insufficient for the $0.057068 per-call fee
- Malformed input schema may return a generic error response
