Custom validation in CRM schema

Custom validation in CRM schema

Validation rules in CRM layouts work nicely, good docs by @Kiran Karthik P 

I'd prefer validating data input 'closer to the schema' when inserting or updating record data - so that values written via API are validated by the CRM.

Is there such a validation layer in CRM API? To my knowledge, this is currently not possible. Some fundamental validations work out of the box - such as mandatory fields or field type, i. e. CRM API would not allow to complete a record update; I am, however, interested in custom validation such as as the social security number validaiton example in the article above.

What is the recommended approach if I want to avoid relying on the external party pushing valid data to CRM?
