Missing required parameter: from_currency

Error message

Missing required parameter: from_currency

What it means

Currency conversion tool guard: the required 'from_currency' argument is missing, not a string, or blank. Fiat or crypto source currency codes (BTC, ETH, USD, EUR) are expected; to_currency is checked separately.

Solutions

1. Supply from_currency as a currency code string, e.g. 'BTC'
2. Ensure both from_currency and to_currency are provided in the same call
