How it works

Global Fraud Signals. One API call.

Checkout Intelligence validates addresses in 120+ countries and runs fraud signals in parallel — IP geo-mismatch for any country, billing comparison, and UK deprivation index — returning a structured result with per-signal risk levels and a single overall risk score.

Global Address Validation

Validate delivery addresses in 120+ countries via OpenStreetMap data. UK addresses are verified against Royal Mail PAF for building-level confirmation. Same response schema everywhere — no country parameter needed.

IP Geo Mismatch — Any Country

Compares the customer's IP geolocation against the delivery address for any country. Country mismatch or >500 km gap triggers an elevated signal — catching VPN use, overseas ordering, and account takeover.

Billing Address Mismatch

Compares delivery and billing addresses. Mismatched outward codes or different cities flag potential card misuse or account sharing. Works for UK and global addresses.

Deprivation Index — UK only

UK/England only: checks the Index of Multiple Deprivation (IMD) decile for the delivery postcode. Deciles 1–2 represent the most deprived 20% of England — a key return-fraud signal. Returns null for non-UK addresses.

Single API Call, Under 200ms

All signals run in parallel in under 200ms. Pass address, customer IP, and billing address — get back structured signals with per-signal risk levels and an overall risk score.

Drop-in Widget & Plugins

Add one <script> tag to your checkout page. Native plugins for Shopify, WooCommerce, BigCommerce, Magento. REST API for any custom stack.

Integration

Live in under 15 minutes

1

Customer enters their address at checkout

The widget (or your backend) captures the delivery address, billing address, and customer IP. UK addresses go to Royal Mail PAF; all others route to OpenStreetMap (120+ countries).

2

Signals run in parallel

Address validated globally, IP geolocated and compared to the delivery location (any country), billing address compared to delivery, and UK deprivation index checked if applicable.

3

Structured signals returned in <200ms

Your backend reads the hidden field (widget) or API response. Act on signals — flag for review, require 3DS, or block at your threshold.

// POST https://agent.apitier.com/v1/checkout/signals // x-api-key: YOUR_API_KEY { "postcode": "SW1A 2AA", "ip": "82.132.229.1", "billing_postcode": "SW1A 1AA" } // Response { "overall_risk": "none", "signals": { "deprivation": { "risk": "none" }, "geo_mismatch": { "risk": "none" }, "billing_mismatch": { "risk": "none" } } }
