FreeTheAI is a free, OpenAI-compatible AI API. One key and one base URL give you dozens of chat models with streaming, tool calling, web search with sourced answers, and image and video generation. Official SDKs are available for Python, JavaScript and TypeScript, and Go.
| Product | What it is |
|---|---|
| Free AI API | The OpenAI-compatible API, the model catalog, and the docs |
| Chat | A web chat for the models on your account |
| Stocks | Free market news, live price cards, and charts. Prices can be delayed; nothing here is financial advice. |
| Prompts | A library of prompts to share and reuse |
The API is OpenAI-compatible, so any client with a base URL setting works. Create a key at freetheai.org, do the daily check-in for free models, then:
Base URL https://api.freetheai.org/v1
Auth Authorization: Bearer YOUR_API_KEY
Models fta/<provider>/<model>, for example fta/zai/glm-5.3
curl https://api.freetheai.org/v1/chat/completions \
-H "Authorization: Bearer $FREETHEAI_API_KEY" \
-H "Content-Type: application/json" \
-d '{"model": "fta/zai/glm-5.3", "messages": [{"role": "user", "content": "Hello!"}]}'The free tier is 50 requests a day, reset at 00:00 UTC. Paid plans are coming soon.
