We recommend using the time API endpoint to query for the API server time if you believe there may be a time skew between your server and the API servers. Your timestamp must be within 30 seconds of the API service time, or your request will be considered expired and rejected. The CB-ACCESS-TIMESTAMP header MUST be number of seconds since Unix Epoch in UTC. If an organization doesn’t offer any of these options, consider not using that service.

If SMS-based 2FA is the only thing available, at the very least require a one-time 2FA code sent to your device every time you login so someone can’t access your account if they have stolen your password. We deliver data from over 25 000 Cryptocurrency Markets. ![]() The requestPath is the full path and query parameters of the URL, e.g.: /v2/exchange-rates?currency=USD. Coinpaprika is a Cryptocurrency Market Research Platform. It is omitted if there is no request body (typically for GET requests). The timestamp value is the same as the CB-ACCESS-TIMESTAMP header. The CB-ACCESS-SIGN header is generated by creating a sha256 HMAC using the secret key on the prehash string timestamp + method + requestPath + body (where + represents string concatenation).
