# Authentication Uiza APIs apply the [HTTP Basic Authentication Protocol](https://swagger.io/docs/specification/2-0/authentication/basic-authentication/), where the client sends HTTP requests with the API key in the Authorization header. Once you have signed up, you can create applications (maximum of 2 applications) with an API Key assigned to each application. You can manage your applications and API Keys in the [Uiza Dashboard](https://app.uiza.io/). All API requests to Uiza *must go* over HTTPS and include a valid API Key. --- # 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://docs.uiza.io/getting-started/authentication.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.
