Info/Exchange Rates

Exchange Rates

Public endpoint for fetching current exchange rates between fiat and cryptocurrencies.

The exchange rates endpoint returns a matrix of current exchange rates between all supported currencies — both fiat (USD, EUR, RUB, etc.) and crypto (BTC, ETH, USDT, etc.).

This is a public endpoint. It does not require authentication and does not require project or sign headers.

Response example

JSON

{
  "state": 0,
  "result": {
    "USD": {
      "USD": "1.00000000",
      "EUR": "0.86090000",
      "RUB": "78.32190000",
      "BTC": "0.00001055",
      "USDT": "1.00000000"
    },
    "BTC": {
      "USD": "94786.69000000",
      "EUR": "81589.12000000",
      "ETH": "29.02345678",
      "USDT": "94786.69000000"
    }
  }
}

How to read the result

The response is a nested object: result[FROM][TO] is the exchange rate for 1 unit of FROM to TO.

result["USD"]["EUR"] = 0.88 means 1 USD = 0.88 EUR
result["BTC"]["USD"] = 94786.69 means 1 BTC = $94,786.69
