Tools (4)

  • get_rates

    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.

  • convert

    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.

  • list_currencies

    List all supported ISO 4217 currency codes and their full names (e.g. { 'USD': 'United States Dollar' }).

  • list_providers

    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.
