Get Rates

Returns live exchange rates from a base currency to a specific selection of quote currencies. Accepts any combination of fiat and crypto on either side.

The key difference from Convert Currency: this endpoint returns raw rates (how much of the quote you get per 1 unit of base), not a converted amount for a specific sum. Use this when you want to store or display rates, and apply the conversion math yourself.

Use this to:

• Fetch only the pairs you need without processing a full rate table
• Display live rates for a curated set of currency pairs
• Build a rate ticker for a fixed set of symbols
• Cache specific rates for use across multiple conversions

Response fields

Field	Type	Description
from	string	The base currency code (mirrors base_currency).
to	object	Map of each requested quote currency to its exchange rate. Each value represents how many units of the quote currency equal 1 unit of the base currency.

Get Rates vs Convert Currency

Both endpoints accept the same base_currency and quote_currency parameters, but serve different use cases:

	Get Rates	Convert Currency
Returns	Raw rate per 1 unit of base	Converted amount for a specific input
Extra param	—	amount
Best for	Storing/displaying rates	Showing an exact conversion result

Use Get Rates when you need the rate itself. Use Convert when you want amount × rate computed for you.
