Frequently Asked questions
What counts as a lookup?
A lookup is any request that retrieves a full UK address from the API, for example when a customer picks their address from the list and the API returns the complete, formatted result. Every plan's allowance is counted in lookups, and your usage dashboard shows the running total in real time.
What happens if I exceed my allowance?
Nothing breaks. Lookups beyond your monthly allowance are charged per lookup at your plan's rate, and your live usage dashboard shows exactly where you are. If you go over regularly we will suggest the plan that works out cheaper, and you can move to it at any time.
Do I need a contract?
No. Standard plans are monthly with no minimum term; you can upgrade, downgrade or cancel any month. Enterprise customers who want annual billing, a service level agreement or volume pricing can have those on a contract, but it is never a requirement to get started.
Can I test the API first?
Yes. Create a free account and you get 30 lookups a day for 30 days with no card required, plus a test environment, full API documentation and support. That is enough to build and test a complete checkout or onboarding integration before you pay anything.
Does AddressBrain support eCommerce checkout?
Yes. Postcode lookup and address autocomplete at the checkout is the most common use of AddressBrain. Shoppers pick a real Royal Mail address in a few keystrokes, your order system receives it as structured fields, and fewer parcels fail or come back. It is already used by UK retailers and shipping platforms including ChannelShipper and Royal Mail's Click & Drop.
Does AddressBrain offer volume pricing?
Yes. The Advanced plan covers 33,000 lookups a month at 3.0p each; above that we offer volume pricing with per-lookup rates that fall as usage grows, and annual terms where that suits you. Contact us with your expected monthly volume and we will put a quote together.
