  • list_metrics List every supported metric with descriptions and required/optional params.
  • currency_convert Convert an amount between major currencies (USD, EUR, GBP, JPY, CAD, AUD, CHF, CNY, INR) with Decimal precision. Static offline table on the free tier; live/historical ECB rates (date/live=true) require a paid plan.
