If you build with an AI coding agent, you can now hand it AddressZen Skills: packaged guidance that teaches Claude Code, Cursor, Codex and other agents how to integrate our widgets and API correctly the first time. Install the set with one command and your agent picks the right package, wires up the API key, and avoids the usual gotchas without you pasting docs into the chat.
Read more →Address Lookup now ships a React integration. The @addresszen/react package gives you a drop-in <AddressLookup> component, so adding address autocomplete to a React app no longer means hand-wiring effects and refs. Available now on npm as @addresszen/react 2.0.0.
Read more →Credit notes issued against your account are now listed alongside invoices in the billing section of the dashboard. Download them for your records without having to ask support.

Corrections to Ireland address rendering in the HERE dataset. Fixes gaps in address point data and improves the handling of Postal Addressing IDs so formatted Irish addresses match expectations.

Sign in to your AddressZen account with a passkey. Use Touch ID, Face ID, Windows Hello or a hardware security key in place of a password. Phishing-resistant by design and faster on every return visit.
The API key details endpoint now returns the key's name, allowed contexts, enabled datasets, and notification settings, so dashboards and integrations no longer need to combine multiple endpoints to display a key's full configuration.
Accounts now belong to an organization. Multiple users can collaborate on the same set of API keys and billing, with role-based permissions controlling what each member can do. Every existing user has been migrated into a single-member organization automatically.
API keys can now be configured with a monthly request limit, complementing the existing daily limit. Cap spend over a calendar month without having to reason about per-day caps.
