## How to call it through Zero

```sh
zero fetch --capability vibesprings-net-48972932
```

Example prompt: Can you pull the daily USD to EUR exchange rates from January 1, 2024 to March 31, 2024, including the average, min, max, and total percent change over that period?

## When to prefer this

Use this endpoint when you need historical daily forex rates with pre-computed statistics (min, max, average, open/close, percent change) for a specific currency pair over a custom date range up to 365 days. Prefer it over a live-rate endpoint when historical trend analysis or summary statistics are the goal rather than a current spot price.

## Known failure modes

- Date range exceeds 365 days — API returns an error; split into smaller ranges
- Invalid ISO currency code — API returns an error about unsupported currency
- Start date after end date — API returns a validation error
- Unsupported currency pair not covered by ECB data — returns empty or error
- Missing required start or end query parameter — returns 400-level error
