API documentation

All models with one key. The API is compatible with OpenAI and Anthropic: replace base_url and the key, and leave the rest of your code as it is.

First requestCopy Anchor Link

1. Create a key

   Open "API keys" in the console and click "Create key". The secret is shown once.

2. Save it in a variable

   Put the key in MORPHOGEN_API_KEY, not in your code.

3. Send a request

   Money is charged from the organization balance by actual usage, in rubles.

Base URLs:

export MORPHOGEN_API_KEY=mg-...
curl https://api.morphogen.ru/v1/chat/completions \
  -H "Authorization: Bearer $MORPHOGEN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "claude-sonnet-5",
    "max_tokens": 300,
    "messages": [{"role": "user", "content": "Привет"}]
  }'

The response comes in the OpenAI format:

{
  "model": "claude-sonnet-5",
  "choices": [{
    "message": { "role": "assistant", "content": "Здравствуйте. Чем помочь?" }
  }],
  "usage": { "prompt_tokens": 9, "completion_tokens": 7 }
}

Take model names from GET /v1/models with your key: the list depends on what the key can access.
