Your first request is a few steps away.

1. Create an account

Open the console and create an account or sign in. Add balance before sending paid requests.

2. Create an API key

Create a separate key for each project in the API keys section. Set a budget and model restrictions. Store the key in server environment variables. Keep it out of browsers, public repositories and mobile clients.

Send the key as Authorization: Bearer YOUR_API_KEY. You can revoke it and inspect its usage from your console.

3. Send a request

Install the OpenAI SDK for your language. Use the exact model ID shown in your console. This is an integration template; availability depends on configured models.

curl https://api.modelseed.dev/v1/chat/completions \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "deepseek-chat",
    "messages": [{"role": "user", "content": "Hello!"}]
  }'
