1. Get an API key

Sign in to your dashboard and open API Keys. Create a key and copy it now — the full value is only shown once. Keys are stored hashed, and start with sk-onehub-.

2. Make your first request

Every endpoint lives under https://www.onehub.design/v1 and is OpenAI-compatible. Here is a chat completion:

curl https://www.onehub.design/v1/chat/completions \
  -H "Authorization: Bearer sk-onehub-xxxxxxxxxxxxxxxx" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "openai/gpt-5-nano",
    "messages": [{"role": "user", "content": "Hello!"}]
  }'

Expected response

{
  "id": "chatcmpl-abc123",
  "object": "chat.completion",
  "created": 1730000000,
  "model": "openai/gpt-5-nano",

      "finish_reason": "stop"
    }
  ],
  "usage": { "prompt_tokens": 9, "completion_tokens": 10, "total_tokens": 19 }
