API KEY and SECRET KEY are required to access the API methods.

Request Authorization and API call example

The resulting API KEY should be sent in the X-API-KEY header with each API call. An additional parameter signature in the X-API-SIGN header is also required.

To get the signature parameter, you must use your SECRET KEY as the HMAC SHA256 operation key and totalParams as its value.

totalParams is defined as the query string concatenated with the request body

Example:

queryString:
from=ETH&to=BTC

HMAC SHA256 signature:

[linux]$ echo -n "from=ETH&to=BTC" | openssl dgst -sha256 -hmac "qVeyDheFpFavNy8kSy1vJc9SG8FZnFeWnJDf9ACx"
(stdin)= a25b61d23c4811ead7738c2124a6d06ebb4b8a4d695da46a2ad8965553d09333

curl command:

[linux]$ curl -H "X-API-KEY: pjFBsaK1HJwQYjZQyy8heEnyyt2G4KyfvDF29lMP" -H "X-API-SIGN: a25b61d23c4811ead7738c2124a6d06ebb4b8a4d695da46a2ad8965553d09333" -d "from=ETH&to=BTC" -X POST https://fixedfloat.com/api/v1/getPair
