OpenAI-compatible API | SRouter Docs

Base URL and key

Set the client base URL to http://localhost:3000/v1 and use a virtual API key created in the dashboard.

from openai import OpenAI

client = OpenAI(
    base_url="http://localhost:3000/v1",
    api_key="sr-live-your_virtual_key"
)

response = client.chat.completions.create(
    model="antigravity/gemini-3.7-flash-high",
    messages=[{"role": "user", "content": "Ping!"}],
    stream=True
)

for chunk in response:
    print(chunk.choices[0].delta.content or "", end="", flush=True)

HTTP endpoint

POST /v1/chat/completions
Authorization: Bearer sr-live-your_virtual_key
Content-Type: application/json

The compatibility route validates ChatCompletionRequestSchema, enforces rate and model access limits, then calls ChatController.CreateCompletion.

curl -N http://localhost:3000/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer sr-live-your_virtual_key" \
  -d '{
    "model": "antigravity/gemini-3.7-flash-high",
    "messages": [{"role": "user", "content": "Ping!"}],
    "stream": true
  }'

Model discovery

Use GET /v1/models to list available models and GET /v1/models/:model to inspect a specific identifier. The model must be visible to the virtual key and available through a connected provider.
