Call this tool for the ECB rate of one currency pair across a window. Returns one row per published day plus the min, max, average and the change. A window wider than the free 90 days is shortened, not refused.
Input schema
| Property | Type | Required | Description |
|---|---|---|---|
| from | string | yes | Base currency of the pair |
| to | string | yes | Quote currency of the pair. Each row is 1 from = X to |
| days | integer | no | Trailing window in calendar days, default 30. Only TARGET business days carry a rate, so 30 days holds about 21 rows. Free reads up to 90 days back; Pro reads the whole series back to 1999-01-04 |
| from_date | string | no | ISO date, inclusive. Overrides days. Free is limited to the last 90 days |
| to_date | string | no | ISO date, inclusive, default today |
| max_rows | integer | no | Cap the table, default 200. min/max/avg still cover the whole window |
