FreeTheAI

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. Also searched as Free The AI, Free The Ai, and FreeTheAi.

[!IMPORTANT] FreeTheAI moved to freetheai.org. The old API at api.freetheai.xyz, its keys, and the old Discord /signup and /checkin commands no longer work. Use the base URL https://api.freetheai.org/v1 with a key from freetheai.org. Old freetheai.xyz links forward to their new pages.

Quick start

1. Create an account at freetheai.org, confirm your email, and make a key under API keys.
2. Do the daily check-in once a day to unlock the free models until 00:00 UTC.
3. Point your app at the base URL.

Base URL    https://api.freetheai.org/v1
Auth        Authorization: Bearer YOUR_API_KEY
Model IDs   fta//, 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!"}]}'

from openai import OpenAI

client = OpenAI(base_url="https://api.freetheai.org/v1", api_key="YOUR_API_KEY")
reply = client.chat.completions.create(
    model="fta/zai/glm-5.3",
    messages=[{"role": "user", "content": "Hello!"}],
)
print(reply.choices[0].message.content)

Chat completions support streaming, tool calling, and the usual sampling settings. List the models your key can use with GET /v1/models. Every error carries an error ID (in the body and the X-Error-ID header); quote it when you ask for help.

SDKs and examples
