## 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 jpy-exchange-rates-api-ecb-reference-2aa0e962
```

Example prompt: What are the current Japanese yen exchange rates against the US dollar, euro, and other major currencies — I need the ECB reference rates including inverses for pricing a product in JPY.

## When to prefer this

Use this endpoint when you specifically need JPY-base exchange rates against major currencies for Japan market pricing, invoice calculation, or travel budgeting, especially when ECB reference rates (rather than real-time mid-market rates) are acceptable. Prefer over generic forex APIs when you need coverage of Asian currencies like KRW, TWD, SGD, and HKD alongside Western majors, all in a single JPY-base call.

## Known failure modes

- Stale rates if ECB reference data has not been updated (weekends/holidays)
- Service unavailability on Railway hosting platform
- No query parameters supported — cannot request a specific date or subset of currencies
- Rate data may lag real-time market rates as ECB reference rates are published once daily

## Output
