# API Basics ### Our API is REST-based on HTTPS * It works with standard HTTP verbs like `GET`, `POST` and `PATCH` * We use standard HTTP error responses to describe errors * All API requests MUST be made over SSL, including outgoing webhooks. Any non-secure requests return as `ssl_required`, and no redirects are performed * POST data should be encoded as standard `application/json` * All our responses are in JSON format --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://developers.cryptopay.me/guides/api-basics.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
