How this service works
Get an email trust score and analysis for an email address. Validates deliverability, identifies disposable/temporary addresses, and provides risk assessment with a numeric trust score from 0-99.
Output
A JSON object containing: Code (success/failure status), Email (the input email echoed back), Score (numeric trust score 0-100), Credits (remaining credits), and Reasoning (AI-generated plain-language explanation of why the email received that score, e.g. domain type, name pattern plausibility, corporate vs. free provider).
Example use cases
Example prompt
“Can you check how trustworthy the email address john.smith@acmecorp.com looks — I want a trust score and an explanation of why it scored that way before I reach out to them.”
Technical details
Endpoint
GEThttps://api.interzoid.com/emailtrustscoreWhen to prefer
Use this endpoint when you need AI-powered trust scoring with human-readable reasoning for individual email addresses, especially when you want to distinguish corporate/legitimate emails from suspicious or low-quality ones. Prefer this over basic syntax validators when you need a risk/trust dimension beyond simple format checking.
Side effects
- Missing or empty 'lookup' query parameter returns an error response
- Malformed email string may return a low score or error
- Invalid API key or insufficient credits returns authentication/payment error
- Rate limiting may occur if too many requests are made in quick succession

Output
{
"Code": "Success",
"Email": "test.user@example.com",
"Score": "4",
"Credits": "0",
"Reasoning": "This email scores critically low: 'example.com' is an IANA-reserved documentation-only domain with no MX records and no real mail infrastructure, making delivery impossible, and the local-part 'test.user' triggers a mandatory penalty for the 'test' keyword, combined resulting in a near-zero score."
