For high-volume and regulated teams

Self-hosted IBAN validation API

The same validation engine and bank data behind our public API, deployed inside your own infrastructure. Lower latency, full data control, and no request ever leaves your environment.

Already integrated with our public API? Switching is usually as simple as pointing your integration at your own URL, the request and response format don't change. Talk to us about self-hosting.
Why teams self-host

Built for the requirements a public API can't meet

After serving thousands of businesses through our public APIs, the same needs kept coming up from larger and more regulated customers.

Security

Data stays in your environment

Validation requests and results never leave infrastructure you control, useful when IBANs and account data can't touch a third-party network.

Latency

No network hop to us

Running the engine alongside your own services cuts the round trip a public API call requires.

Integration

Fits your existing setup

Deploy it as part of your own stack and workflows instead of adapting your architecture around an external dependency.

Flexibility

Customize what you need

Adjust configuration and deployment to match your product, rather than working within a one-size-fits-all public endpoint.

Compliance

Meet local regulatory requirements

Keep validation traffic within the jurisdiction or network boundary your regulator expects.

FAQ

Common questions about self-hosting

How is self-hosted different from the public API?

Same validation engine and dataset, deployed inside your own infrastructure instead of calling ours. Requests never leave your environment, which is often the deciding factor for regulated or high-volume teams.

Do I have to migrate my integration to switch?

No. If you're already using the public IBAN API, the request and response format stay the same, so switching to a self-hosted deployment is usually just a matter of pointing your integration at your own URL.

Who typically needs a self-hosted deployment?

Teams with strict data residency or compliance requirements, and high-throughput products, remittance platforms, payment gateways and crypto on/off-ramps among them, that need to keep validation traffic inside their own network.

Do you handle the setup?

Either way works. You can run the setup yourself with minimal server requirements, or we can handle deployment for you as part of onboarding.
