What this server can do

5 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.

convert(to, from, amount)
Convert an amount from one currency to another at the current rate. Indicative developer-grade reference rates (aggregated market data + public reference rates), not for settlement or trading. Required: from, to, amount.
get_range(base, cursor, symbols, end_date, start_date)
Get a daily time-series of exchange rates over a date range (business days). Capped at 366 rows per call; when has_more is true, pass next_cursor as the cursor parameter to fetch the next page. Indicative developer-grade reference rates (aggregated market data + public reference rates), not for settlement or trading. Required: base, symbols, start_date, end_date.
get_rate(base, date, quote)
Get the current — or historical, with date — exchange rate from one currency to another. Indicative developer-grade reference rates (aggregated market data + public reference rates), not for settlement or trading. Rates update ~60s for real-time currencies through the trading week when the live overlay is active; the source field on every response is the authoritative freshness indicator (live | ecb_daily | fred_daily) — rates fall back to ECB or FRED daily reference during market closures, data-source unavailability, or low liquidity. market_session on every response indicates open, weekend, or interbank_closed. Required: base, quote.
list_currencies
List all supported currencies with name, decimal precision, minor units, and whether the pair is derived (triangulated). Use this before other tools to discover valid currency codes.
search_docs(limit, query)
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. Required: query.

Signals

These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.
