Documentation

An OpenAI-compatible API that routes your requests to the cheapest capable model across multiple providers.

How it works

Instead of specifying a model, you specify a capability tier (economy, standard, or premium) and an optimisation preference (cheap, fast, balanced, or quality). The router selects the best model from all available providers.

If a provider goes down, the circuit breaker reroutes automatically. If a cheaper model launches, you benefit without changing code. Context-window guards ensure your input always fits the selected model.

Quick start

1. Sign up — go to /profile, enter your email, get a login code. New accounts get $1 free credit.

2. Create an API key — on the profile page, generate a key (starts with mr_sk_).

3. Make a request — point any OpenAI-compatible client at https://api.lxg2it.com:

# Free models — uses economy tier (Groq/Cerebras, no cost)
curl https://api.lxg2it.com/v1/chat/completions \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "economy",
    "messages": [{"role": "user", "content": "Hello!"}]
  }'

economy routes to free models via Groq and Cerebras — no credits consumed. Your $1 sign-up credit can also be used with standard or premium tiers — or pin a specific model like claude-sonnet-4-6. See Tiers.

That’s it. The response format is identical to OpenAI’s — any existing client library or tool that speaks the OpenAI API will work without modification.
