API Reference
An overview of the Qufas AI developer API.
Overview
Qufas AI exposes an OpenAI SDK-compatible Chat Completions subset, related inference endpoints, and read-oriented platform APIs for model discovery, usage, balance, and API key metadata.
The primary inference endpoint is POST /v1/chat/completions. Use https://qufas-ai.vercel.app/v1 as the base URL.
OpenAPI Specification
The canonical specification uses OpenAPI 3.0.3. Its server URL is the API origin; operation paths already include /v1, so clients must not append another /v1 when resolving paths from the specification.
