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.

get_rate

Get the current (or, with date, historical) exchange rate from one currency to another. Indicative developer-grade reference rates (live market data + public reference rates), not for settlement or trading. Rates update ~60s for real-time currencies through the trading week when the live feed is active; the source field on every response is the authoritative freshness indicator (live | ecb_daily | market_daily); rates fall back to official daily reference data during market closures or data-source unavailability. market_session on every response indicates open, weekend, or interbank_closed.

get_usd_index

Get the latest independently calculated USD index. dxy-reconstructed uses the published six-currency basket formula but is not the official index. usd-strength is the versioned exchangerate.dev equal-weight 13-currency index, with 2026-01-02 = 100. Both require a complete, time-aligned basket.

  "additionalProperties": false
}

list_official_rate_tables

  "type": "object",
  "properties": {},
  "additionalProperties": false
}

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.

start_checkout

Open a billing URL for an explicitly selected eligible plan. After human confirmation, a Free account without a subscription receives a one-hour Stripe Checkout URL; an existing subscriber receives Stripe billing management instead. Plans not offered to the account are refused. Cancellation creates nothing and account identifiers are never accepted from the model.
