Pooled fail-over router; most routes substitute models warning
DreamPrompting pools upstream free tiers and fails over between them. Free is 500,000 tokens and 5,000 requests per rolling 24 hours, 100 requests per minute per IP, no card. Only the nine listed routes returned the requested model on September 15 (retried twice). The other 19 routes (Cohere, Gemini, Qwen, Llama, Granite, Mistral Small and Large, gemma-4) consistently served Nemotron 3 Super, gpt-oss-120b or Codestral instead and are excluded. Prompts may be stored or publicly shared per the provider.

Use it

FreeLLMAPI is a self-hosted router you run yourself. Install it, paste in your free DreamPrompting key, and groq/openai/gpt-oss-20b answers on an OpenAI-compatible endpoint at http://localhost:3001/v1. No credit card, no hosted middleman: your prompts and your provider keys never leave your machine.

Install the router (macOS, Linux, WSL)
curl -fsSL https://freellmapi.co/install.sh | bash
Install the router (Windows PowerShell)
iwr -useb https://freellmapi.co/install.ps1 | iex
Call groq/openai/gpt-oss-20b with curl
curl http://localhost:3001/v1/chat/completions \
  -H "Authorization: Bearer freellmapi-your-unified-key" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "groq/openai/gpt-oss-20b",
    "messages": [{"role": "user", "content": "Say hi in five words."}]
  }'
The same request in Python (openai)
from openai import OpenAI

client = OpenAI(
    base_url="http://localhost:3001/v1",
    api_key="freellmapi-your-unified-key",
)

resp = client.chat.completions.create(
    model="groq/openai/gpt-oss-20b",
    messages=[{"role": "user", "content": "Say hi in five words."}],
)
print(resp.choices[0].message.content)

The router answers on /v1/chat/completions and every other OpenAI surface, plus the Anthropic Messages API, so existing clients need only a new base_url. Swap the model id for auto and the router picks the best free model that is still under its limits. Full reference: docs/api.md.
