base44

base44 generates React SPAs (Vite + Tailwind).

What you'll add​

International address autocomplete on any address form, powered by the Address Lookup widget.

1. Get an API key​

  • Quick test: paste ak_test as your key. Capped at 5 lookups/day. Will break in production.
  • Real key: sign up at addresszen.com/signup for a free trial balance.

2. Starter prompt​

Paste this into the base44 chat with your ak_… key dropped in. It points the agent at a reference page carrying the React-specific integration rules — including where the key should live for your plan — so the prompt itself stays short and the agent handles the rest:

Add international address autocomplete to the address form using the
AddressZen Address Lookup widget.

This is a React app. Fetch and follow the integration rules at:
https://docs.addresszen.com/docs/integrations/base44-prompt.md

My API key is ak_xxxxxxxx — place it wherever those rules say it belongs for
this app (it's a publishable browser key). After deploying, print the app's
origin in chat so I can add it to the key's Allowed URLs.

The full rule set lives at base44 integration rules if you want to read it yourself.

3. Lock down the key​

Browser keys are public — Allowed URLs is the lock. After deploy, add both origins to your key:

  • The base44 preview: https://<your-app>.base44.app
  • Your custom domain, if attached (Builder plan and above)

Forgetting the custom domain returns silent 401s only on the published site — preview keeps working, which is the most confusing failure on this platform.
