The global data layer for your app
One API for geolocation, currency and identity validation — built by developers who were tired of stitching five vendors together.
Locanium started with a frustration every engineering team knows: shipping something simple — localize a price, verify an email, block a fake signup — meant wiring up three or four different vendors, each with its own key, SLA, billing and quirks.
So we built the layer we wanted to use: one REST API, one key, and eight endpoints for geolocation, currency and identity validation — with the latency, uptime and compliance a production system actually needs. Today it powers checkout, onboarding and fraud flows for teams around the world.

How we build
Developer-first
Clear endpoints, honest docs and SDKs. If it takes more than an hour to integrate, we’ve failed.
Reliable by default
Multi-region, 99.99% uptime and sub-40 ms responses — infrastructure you can build a business on.
Privacy by design
We don’t resell lookups, we process in-memory, and we offer EU data residency and DPAs.
Global from day one
Coverage in 240+ countries across geolocation, currency and identity — one integration, worldwide.
From one endpoint to a global layer
- 2019
The frustration
Locanium starts with one endpoint and one belief: location and identity data should be a single integration, not five.
- 2021
API v1 is GA
All eight endpoints — geolocation, timezone, currency and validation — go generally available under one key.
- 2022
Built for compliance
EU data residency, custom DPAs and a published sub-processor list arrive for regulated teams.
- 2023
Sub-40 ms, everywhere
New points of presence bring median latency under 40 ms across most regions.
- 2024
99.99% and accountable
A public status page and an uptime SLA teams can put their name behind.
- 2026
240+ countries
Coverage across geolocation, currency and identity — a genuinely global data layer.
