Technical reasons why no global API for financial fraudsters and sex offenders?

In 2024, what are the technical reasons why there is no worldwide API for financial fraudsters + sex offenders (even community reported) + spam lists?

An endpoint/ API that accepts full name, email address, image, video and returns true/false

Context: I'm building an id and verification workflow for a community of women and vulnerable families who would like predators (online, mostly) out of their social communities. I haven't been able to find any reliable way to verify this and integrate for an engineer.

Many thanks for your patience.
