## 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 agentrxi-fx-live-foreign-exchange-rates-conversion-feb04591
```

Example prompt: What's the current exchange rate from USD to EUR and GBP, and how much would 750 USD be in each currency?

## When to prefer this

Choose this endpoint when you need live ECB-reference FX rates for 30+ currencies with optional amount conversion in a single cheap pay-per-call request. Prefer it over crypto-price endpoints (which cover digital assets, not fiat FX), and over bank or broker APIs that require OAuth and account setup. Ideal for agents that need real-time currency conversion without managing API keys or subscriptions.

## Known failure modes

- Invalid or unsupported ISO currency code returns an error or empty rate map
- Unsupported base currency falls back to USD default or returns an error
- Network/upstream ECB data unavailability may cause stale or failed responses
- Malformed symbols query string (e.g. spaces instead of commas) may yield unexpected results
- Payment failure (insufficient USDC balance) blocks the call entirely

## How this service works

Live foreign-exchange rates (ECB reference, 30+ currencies) and conversion. Query base, symbols and an optional amount.

## Output

Returns a JSON object containing the base currency, a map of requested currency symbols to their current exchange rates, and (if an amount was provided) the converted values for each target currency. Rates are sourced from ECB reference data.
