Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• get_rates open 10h ago

  Latest or a single day's exchange rates. The raw-rate companion to `convert`. With `provider`, published rates from one or more institutions: on its own base the digits are as published, with the date they took effect.

• list_providers open 10h ago

  List the institutions whose rates Frankfurter relays, with key, rate type, frequency (daily, monthly or quarterly) and coverage dates. Use a key as `provider` in `convert` or `get_rates` for that institution's published rates instead of the blend.

• convert unknown never probed

  Convert an amount from one currency to another. Returns {amount, currency} rounded to the target's minor units. Upstream rounds rates per direction; for low-value sources, flip via `get_rates` for more precision. Pass `provider` to use one institution's published rate, e.g. UST for a U.S. Treasury reporting rate.
