* For private requests, the `timestamp` parameter (in milliseconds) must be included in the query string. The timestamp is valid within a range of ±20 seconds.
* Private requests require `PIONEX-KEY` (API Key) and `PIONEX-SIGNATURE` headers.
* GET requests: additional parameters are passed in the query string.
* POST/DELETE requests: parameters are passed in the request body as JSON (`application/json`).
* Zero-valued number parameters are disregarded.

**Signature Construction:**
