Tools 4 found in our last check

  • get_rates

    Latest or dated reference rates. Provider rates retain published digits on their own base. Returns rate records; if any provider fails, returns {rates,errors} preserving successes. Retry only failed providers.

  • convert

    Convert money using a reference rate. Returns {amount,currency}, rounded to the target's minor units (8 significant figures for metals/crypto). Set details for the rate and effective date too; identity conversions have rate 1 and date null.

  • list_currencies

    Find currency, metal and crypto codes by code or name. Returns {code:name}; omit query for all, including historical currencies.

  • list_providers

    Find rate providers with keys, rate types, base currencies, frequency and coverage dates. Filters combine; omit for all. Use a key as provider in convert or get_rates; a provider publishing several series lists datasets, whose keys select one.
