-## API
 
-See the API docs linked above.
+## API requests
 
-They have an API for text and one for images. The text one includes a path for an API that follows the OpenAI specification, so it can be used easily with the `openai` package or LangChain's OpenAI connector.
+See the [API docs](https://github.com/pollinations/pollinations/blob/master/APIDOCS.md)

+See sections below for tips on using the text and image endpoints.
 
-## Browser-based
+The links below will work fine in the browser as `GET` requests but these are intended to handled in a client e.g. using Python or React for building the URL and displaying the content for a user.
