Network Biometrics API is one of 7 APIs that [TMT ID](https://apis.io/providers/tmt-id/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Mobile Identity, SIM Swap, Device Intelligence, and Age Assurance. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, and an API reference.

The Phronesis-derived flagship, a single POST that assembles a configurable set of mobile network signals about a number and device — SIM swap and device change look-back windows, GSMA device blacklist status, reachability, roaming, account type and tenure, and personal-data matching — plus the deprecated v2 Number Assurance operations for assured registration and assured age.
