# Validation Services

Fraud risk queries on the account holder's contact details: IP address, email, and phone number.

None of these services handle assets: the data to be evaluated travels in the route itself; they do not include a field `source` nor header `operation-id`.

#### Available services

* [**IP Validation**](/docs.facephi-en/rest-api/midapi-v2/validation-services/ip-validation.md): Evaluates the fraud risk of an IP address.
* [**Email Validation**](/docs.facephi-en/rest-api/midapi-v2/validation-services/email-validation.md): Evaluates the fraud risk of an email address.
* [**Phone Validation**](/docs.facephi-en/rest-api/midapi-v2/validation-services/phone-validation.md): Evaluates the fraud risk of a phone number.
