BIN IP Checker lets you send a BIN and an IP address, then returns a simple response envelope with a numeric code and a success flag. Use it when you need to check card issuer information against an IP-based signal in your backend flow.
The request is straightforward: pass bin and ip as query parameters. The response schema is minimal, so you should expect the standard envelope fields and any additional module blocks returned by the service. That makes it easy to integrate into risk checks, checkout validation, or fraud-routing logic without parsing a large payload.
Because the output is lightweight, this service fits well into real-time decisioning. For example, you can call BIN IP Checker during payment initiation to gate suspicious combinations before you move to authorisation, or use it in a rules engine alongside other identity and transaction checks.
If you just need a quick yes/no-style result with a code for handling, BIN IP Checker keeps the contract simple.

GUIDE
Quickstart
Use the following request to analyze a payment card BIN and compare it with an IP address to detect potential country mismatches and fraud indicators.

What you'll get back
A successful request returns details about the payment card BIN, IP address intelligence, and whether the issuing country of the card matches the IP address location.

About this endpoint
What it does
Checks a card's BIN against an IP address to verify whether the card's issuer country matches the IP's geolocated country — a common signal for cross-border fraud detection.
