Mistral

Mistral chat models are called through one simple endpoint: send a messages array plus the model slug and get the reply text back. This family exposes 4 models.

Overview

Send a standard messages array (user / assistant / system roles). Billing is deducted from your credit balance per response; the response includes your remaining balance.

Authentication

Create an API key at /api-keys, then send it as a Bearer token. Requests from the browser while logged in also work via the session cookie.

Authorization: Bearer <YOUR_API_KEY>

OpenAI-compatible Chat Completions

POST

POST https://api.lithovas.com/v1/chat/completions

Use this endpoint for developer integrations: point your OpenAI SDK base_url to https://api.lithovas.com/v1 and send a Lithovas API key.
