Quickstart

Prerequisites

An OpenModel account — sign up at console.openmodel.ai
An API key — create one in the Console under API Keys

Set Your Base URL

All OpenModel API requests go through:

https://api.openmodel.ai

Make Your First Request

Choose your preferred API protocol:

Responses API

curl https://api.openmodel.ai/v1/responses \
  -H "Authorization: Bearer $OPENMODEL_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-5.4",
    "input": "Hello, who are you?"
  }'

Anthropic Format (Messages API)

curl https://api.openmodel.ai/v1/messages \
  -H "x-api-key: $OPENMODEL_API_KEY" \
  -H "content-type: application/json" \
  -H "anthropic-version: 2023-06-01" \
  -d '{
    "model": "claude-sonnet-4-6",
    "max_tokens": 1024,
    "messages": [
      {"role": "user", "content": "Hello, who are you?"}
    ]
  }'

Gemini Format

curl "https://api.openmodel.ai/v1beta/models/gemini-3.5-flash:generateContent?key=$OPENMODEL_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "contents": [
      {"parts": [{"text": "Hello, who are you?"}]}
    ]
  }'

DeepSeek Format (Messages API)

DeepSeek, DashScope, and Xiaomi models are all accessible through the Messages API using the Anthropic SDK — just change the model name.

curl https://api.openmodel.ai/v1/messages \
  -H "x-api-key: $OPENMODEL_API_KEY" \
  -H "content-type: application/json" \
  -H "anthropic-version: 2023-06-01" \
  -d '{
    "model": "deepseek-v4-flash",
    "max_tokens": 1024,
    "messages": [
      {"role": "user", "content": "Hello, who are you?"}
    ]
  }'

Tip: The code above is identical to the Anthropic Format example — only the model name changes. Replace deepseek-v4-flash with any supported model: qwen3-max, mimo-v2.5-pro, etc. See Available Models for the full list.
