qixing-jk/all-api-hub ? reverse-engineered prompt

Build me a browser extension for managing multiple AI relay accounts in one place.

I want a clean dashboard where I can add site URLs and API keys, then quickly see balances, usage, account status, and model prices across different services. It should be able to check in to supported sites automatically, show announcements and alerts, and let me test whether a key or model actually works before I try using it elsewhere.

Please also make it easy to capture API keys from webpages, save them locally, and export them with one click into tools like Cherry Studio, Claude Code Router, and similar clients. I’d like a way to compare prices between sites, sync or redirect model names, and manage gateway channels from the same app.

Keep the data local by default, with an optional encrypted WebDAV backup and sync. If you need to look up current docs or integration details online, feel free to do that.
