# Firebase endpoints did not answer an anonymous request

The database and storage endpoints refused a request that carried no sign in.

## Why AI-built apps get this

Firebase ships with open rules while you build, and the console says so. Turning them into real rules is a separate task with no deadline attached, and the app behaves identically either way.

## Evidence line

GET https://example-app.firebaseio.com/.json returned 200 with data

## The fix

Nothing to change here.

## Prompt

Keep the Firebase rules closed to anonymous callers.
