Authentication

All API endpoints require authentication via an API key.

API Key​

Include your API key in the X-Api-Key header:

curl -H "X-Api-Key: YOUR_API_KEY" \
"https://api.iqxlookup.neivi.es/api/v1/email?address=user@example.com"
Header only

The API key must be sent via the X-Api-Key header. Query parameter authentication is not supported.

Obtaining an API Key​

  1. Log in to the IQX Lookup Dashboard
  2. Navigate to API Tokens
  3. Click Create Token and provide a label
  4. Copy the generated token value — it won't be shown again

Security​

  • All API traffic is encrypted via HTTPS/TLS
  • API keys follow the format: ALk- followed by 36 alphanumeric characters
  • You can create multiple tokens for different applications
  • Revoke tokens instantly from the dashboard
  • Regenerate tokens if compromised
