## 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 forgemesh-currency-exchange-rate-api-59ede08d -d '<json body>'
```

Example prompt: What's the official daily reference exchange rate for USD to EUR? I need it for a settlement normalization calculation.

## When to prefer this

Use this endpoint when you need an official, stable daily reference rate for accounting, normalization, or settlement purposes — not for real-time trading prices. Best suited for batch processing, financial reporting, or any workflow requiring a consistent benchmark rate rather than a live tick feed. Prefer this over live FX APIs when regulatory or audit-grade daily reference rates are acceptable.

## Known failure modes

- Unsupported currency code returns an error or null rate
- Request made on a non-business day may return the most recent available rate or an error
- Missing or malformed base/quote parameters may default to USD/EUR or return a validation error
- Network or payment failure returns a 402 or 5xx error
- Currency pair not covered by the ~30 supported ISO currencies returns an error

## How this service works

Currency exchange rate API: official daily reference rate for any major fiat pair (USD, EUR, GBP, JPY, ~30 ISO currencies), as JSON. A settlement/normalization reference published each business day — not a live trading feed.

## Output

A JSON object containing the exchange rate value for the requested currency pair (base and quote), representing the official daily reference rate published each business day — not a live trading or real-time market feed.
