# Proteales AI Service

> Proteales AI Service is a unified API gateway that lets developers access hundreds of artificial intelligence and large language models from multiple providers through a single API endpoint and key.

The API is OpenAI-compatible: point any OpenAI SDK at the base URL `https://ai.proteales.com/v1` and send `Authorization: Bearer <key>`. Keys are created on the Tokens page (https://ai.proteales.com/token) after signing in. Prices are in USD per 1M tokens (input / output).

## Getting started

- [Models](https://ai.proteales.com/models): browse every available model with prices, limits and capabilities
- [Model list (JSON)](https://ai.proteales.com/api/model_list): machine-readable list of available models and prices
- [Model detail (JSON)](https://ai.proteales.com/api/model_list/detail?model=deepseek%2Fdeepseek-v4-flash): one model's limits, capabilities and price; pass the model id
- [Chat completions](https://ai.proteales.com/v1/chat/completions): `POST`, OpenAI Chat Completions request and response format, streaming with `"stream": true`

Example request:

```bash
curl https://ai.proteales.com/v1/chat/completions \
  -H "Authorization: Bearer $PROTEALES_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model": "deepseek/deepseek-v4-flash", "messages": [{"role": "user", "content": "Hello!"}]}'
```
