## 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 currency-crypto-latest-rates-4915f357 -d '<json body>'
```

Example prompt: What are today's exchange rates from USD to EUR, GBP, and JPY — pull the latest ECB rates for me.

## When to prefer this

Choose this endpoint when you need reliable, ECB-sourced fiat currency exchange rates at low cost ($0.001 USDC per call). Prefer it over alternatives when you need official ECB reference rates for EUR-denominated or multi-currency lookups, or when working in a crypto-native payment context (x402/USDC). Not suitable when you need intraday tick-level FX rates or real-time crypto prices (use the sibling crypto endpoint for that).

## Known failure modes

- Unsupported or invalid base currency ISO code returns an error
- Invalid symbols in the target list may be ignored or cause an error
- Payment failure (x402) if USDC balance is insufficient
- Rate data may be cached or slightly delayed relative to real-time market prices
- ECB rates are typically end-of-day, not intraday tick data

## How this service works

Fiat exchange rates (ECB via Frankfurter) and crypto prices (CoinGecko) with x402 payments.

## Output

A JSON object containing the base currency, the date of the rates, a map of target currency codes to their exchange rates relative to the base, a cached boolean indicating if the response was served from cache, and the data source (ECB via Frankfurter).
