Authentication

Header	Value
`X-RapidAPI-Key`	Your RapidAPI secret key
`X-RapidAPI-Host`	`fast-price-exchange-rates.p.rapidapi.com`

Query parameters

Parameter	Type	Required	Description
currency	string	Yes	Quote currency code. Accepts both fiat and crypto symbols. Examples: `USD`, `EUR`, `BTC`, `ETH`
detailed	boolean	No	When `false` (default): keys are plain symbols — crypto tickers and fiat ISO codes mixed together (`"ETH"`, `"EUR"`). When `true`: keys use `"SYMBOL:NAME:TYPE"` format where `TYPE` is either `CRYPTO` or `FIAT` (`"ETH:ETHEREUM:CRYPTO"`, `"EUR:EURO:FIAT"`).

Response fields

Field	Type	Description
to	string	The quote currency code (mirrors the `currency` query parameter).
from	object	Combined map of all source assets (fiat + crypto) to their rates. Each value represents how many units of the quote currency equal 1 unit of the source asset. Key format depends on the `detailed` parameter: • `false`: plain symbol — `"EUR"` or `"BTC"` • `true`: `"SYMBOL:NAME:TYPE"` where TYPE is `FIAT` or `CRYPTO`

Key format (detailed=true)

SYMBOL:FULL NAME:TYPE
  │        │       └─ "FIAT" or "CRYPTO"
  │        └─ full asset name in uppercase
  └─ ticker or ISO code

Conversion formula

Each rate is source → quote. To convert an amount:

quoteAmount = sourceAmount × rate

Example: "EUR": 1.176 means 1 EUR = 1.176 USD → 500 EUR × 1.176 = $588

Relationship to All From Base

This endpoint is the mirror of All From Base:

all/from?currency=USD → to.EUR = 0.844 (1 USD = 0.844 EUR)
all/to?currency=USD → from.EUR = 1.176 (1 EUR = 1.176 USD)

The two rates are reciprocals: 0.844 × 1.176 ≈ 1.0
