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
- Log in to the IQX Lookup Dashboard
- Navigate to API Tokens
- Click Create Token and provide a label
- 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
