## 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 agentsvc-io-exchange-rates-api-67a4b90d -d '<json body>'
```

Example prompt: What are today's exchange rates from EUR to USD, GBP, JPY, and CHF? I need the latest ECB rates.

## When to prefer this

Choose this endpoint when you need official European Central Bank exchange rates without managing API keys or subscriptions — ideal for AI agents that need to pay per call with USDC on Base. It is particularly well-suited for EUR-based rate lookups across many currencies simultaneously. Prefer this over rolling your own forex integration when you want zero setup overhead and ECB-authoritative data.

## Known failure modes

- Unsupported currency code returns an error or empty rates object
- Empty symbols array may return all currencies, which could be a large payload
- Network or upstream ECB data source unavailability causes failure
- Invalid base currency string causes a 400-level error
- Payment failure (insufficient USDC balance) blocks the call entirely
