Both require a complete, time-aligned basket.
- `get\_rate`: Get the current \(or, with date, historical\) exchange rate from one currency to another.

Capped at 366 rows per call; when has\_more is true, pass next\_cursor as the cursor parameter to fetch the next page.

- `search\_docs`: Search the exchangerate.dev FAQ corpus via BM25. Returns the top-K matching questions and answers with relevance scores. Use before answering how-to / pricing / data-sourcing questions so you cite the canonical text instead of guessing from training data.
- `list\_official\_rate\_tables`: List the countries and rate types with government-published exchange rates \(for example IDN tax, GBR customs, USA government-reporting\). Country codes are ISO 3166-1 alpha-3; use them with get\_official\_rate.
- `get\_official\_rate`: Get the exchange rate a government authority published for a date \(tax, customs, central bank\), with the period it is valid for. These are the published values, not market rates. Every plan gets the rate valid today; a past date needs a paid plan. Pairs the authority does not publish are refused.
