Authentication

How to authenticate with the SerperMatrix API.

Every API request requires an API key in the X-API-KEY header.

Getting your key

  1. Sign up at serpermatrix.com/auth/signup
  2. Go to Dashboard → API Keys
  3. Click Create Key
  4. Copy the key — it is shown only once
Your API key grants full access to your credits. Never expose it in client-side code.

Usage

POST /api/v1/search
X-API-KEY: sm_live_xxxxxxxxxxxxxxxxxxxx
Content-Type: application/json

Security best practices

  • Store keys in environment variables, never in source code
  • Rotate keys regularly from the dashboard
  • Revoke any key you suspect is compromised
