> An overview of UNLI API.

## Endpoints

UNLI exposes two conversation endpoints, one per API format, plus a model listing.

- [Chat Completions](https://docs.unli.dev/chat-completions.md): `POST /v1/chat/completions`, OpenAI format
- [Messages](https://docs.unli.dev/messages.md): `POST /v1/messages`, Anthropic format
- [Models](https://docs.unli.dev/models.md): `GET /v1/models`, Available models and their capabilities

## What you get

- **Unlimited tokens**: Build without tracking usage limits.
- **Automatic model routing**: Set `model` to `auto` (or `unli-auto` on Messages) and UNLI picks a model for each request.
- **Drop-in compatibility**: Works with the official OpenAI and Anthropic SDKs. Change the base URL and API key.
- **Streaming**: Real-time responses over Server-Sent Events (SSE).
- **Vision**: Analyze and describe images sent by URL or base64.
- **Tool calling**: Function calling and structured outputs.
- **Multi-turn context**: Conversation context carries across turns.
- **Sampling controls**: Tune output with `temperature`, `top_p` and `top_k`.
- **Low latency**: Optimized for fast response times.
