Result object

The result object is only returned when the status of the check is complete . It has two components - outcome and breakdown.

Outcome

The outcome attribute represents the overall check result. Returned values include:

1. clear: Indicates every analysis type conducted returned a successful result.

2. attention: Indicates at least one of the analysis results requires attention.

Breakdown

The breakdown comprises the following objects:

riskAnalysis object

The risk analysis results. For each conducted analysis, the returned values include:

1. clear: Indicates the analysis returned a successful result.

2. attention: Indicates the analysis returned a result that requires a review.

It has the following constituents:

• validFormat: Indicates if the email number is properly formatted.

• dataLeakAnalysis: Indicates if this email is associated with a recent database leak from a third party.

• disposableEmailAnalysis: Whether the email is suspected of belonging to a temporary or disposable mail service which are often used for fraud.

• domainValidity: Indicates whether the email domain (e.g., example.com) has valid DMARC, MX, and A records, which help verify its authenticity and email deliverability.

• riskLevel: A value between 0 and 100 that estimates how likely an email address is associated with fraudulent activity. You may use the ranges below as guidance when interpreting results:

  • 0–50: No indicators of fraud detected.

  • 51–75: Suspicious range. Not necessarily fraudulent, but higher scores here suggest a stronger likelihood of risky or harmful activity.

  • 76–100: High-risk number. Strongly associated with fraud or abuse and should not be trusted.
