## About

## What it does
IP Address Lookup lets you send an IP address and get a structured lookup response back. The endpoint accepts a single required `ip` query parameter and returns an envelope with a numeric `code`, a `success` flag, and additional module data in the response body.

Use IP Address Lookup when you need to resolve an IP as part of sign-in checks, fraud signals, analytics, or request enrichment. It fits into workflows where you want to attach location-aware context to an IP without building your own lookup layer.

Because the response schema is intentionally open-ended beyond `code` and `success`, you can consume the module blocks your integration needs without assuming a fixed payload shape. That makes the service suitable for lightweight validation and broader geolocation pipelines alike.

If you are routing traffic, flagging suspicious activity, or segmenting users by network origin, IP Address Lookup gives you a simple input and a machine-readable result to build on.
