POST /v1/chat/completions

Some models are invoked with a chat-completions style body (messages array) instead of the Responses input field. The dashboard and model catalog indicate which route applies.

​
Request headers

Same as Responses: x-api-key, x-project-id, content-type: application/json.

​

Example

curl --location 'https://api.zerogpu.ai/v1/chat/completions' \
  --header 'content-type: application/json' \
  --header 'x-api-key: YOUR_API_KEY' \
  --header 'x-project-id: YOUR_PROJECT_ID' \
  --data '{

    "messages": [
      { "role": "user", "content": "Your input text here..." }
    ]
  }'
Install the official SDK from npm or PyPI (pip install zerogpu-api). Source: zerogpu/SDK. Response JSON shape depends on the model; handle errors the same way as API error codes.
