1. API Category Browsing/Searching
The "Use API" - "API Market" page gathers a wealth of API documentation. In the API categories section, you can find detailed configuration documents for various API uses, including Language Models, AI Painting, Image Processing, Video Generatiom, Audio-Video Processing, Data Processing, RAG-related, and more.

2. Selecting an API
Taking the "Language Model" OpenAI as an example, clicking on OpenAI will redirect you to the 302.AI API Documentation - OpenAI Guide, which provides detailed instructions on how to use the API to call OpenAI's language model.

3. Debugging the API
You can then debug the API directly within our API documentation.
4. Copying the Key and Filling in Environmental Variables
Copy the API Key generated in the backend and fill it into the environment variables (only needs to be done once, it will be remembered and automatically applied afterward).
API Key can be found in the Management Backend - Use API - API Keys. If you don't have one, please add it first. After adding it, click the small eye icon first, then click the copy icon to copy it.

5. Send for Debugging
To debug, simply click send.
