OpenAI and Anthropic Compatibility

EmpirioLabs AI exposes compatibility endpoints so you can adopt the platform without rewriting existing integrations. Point your OpenAI or Anthropic SDK at the EmpirioLabs base URL and start making requests immediately.

OpenAI-compatible Chat Completions

POST /v1/chat/completions

Accepts the same request body as the OpenAI Chat Completions API. Supports messages, model, stream, temperature, max_tokens, and other standard parameters.

$
curl "https://api.empiriolabs.ai/v1/chat/completions" \
>
  -H "Authorization: Bearer $EMPIRIOLABS_API_KEY" \
>
  -H "Content-Type: application/json" \
>
  -d '{
>
    "model": "qwen3-max",
>
    "messages": [{ "role": "user", "content": "Summarize this in one sentence." }]
>
  }'

Using the OpenAI Python SDK:

1
from openai import OpenAI
2
3
client = OpenAI(
4
    api_key="sk-empiriolabs-your_key_here",
5
    base_url="https://api.empiriolabs.ai/v1",
6
)
7
8
response = client.chat.completions.create(
9
    model="qwen3-max",
10
    messages=[{"role": "user", "content": "Hello!"}],
11
)

OpenAI Responses-compatible endpoint

POST /v1/responses

Accepts the same request body as the OpenAI Responses API. Supports model, input, instructions, and related fields.

$
curl "https://api.empiriolabs.ai/v1/responses" \

  -H "Authorization: Bearer $EMPIRIOLABS_API_KEY" \
>
  -H "Content-Type: application/json" \
>
  -d '{

    "max_tokens": 256

  }'

SDK configuration cheat sheet

Model support

Not every model supports every endpoint format. Use GET /v1/models/{modelId} to check a specific model’s capabilities (streaming, system prompt, web search, images, video) and supported_parameters before integrating.
