# Email verifier browser extension

A small, open-source Chrome/Edge extension: check an address from the toolbar popup, or right-click one selected on any page.

## How to install it

1. Download or clone the [browser-extension folder](https://github.com/sudosuraj/email-verifier/tree/main/browser-extension) from GitHub.
2. Open chrome://extensions and turn on Developer mode.
3. Click Load unpacked and select the folder.
4. Paste an API key from your account's Developers page into the extension's Options.

## Questions

**Is this on the Chrome Web Store?**
Not yet - it's open source and installs in under a minute through Chrome's (or Edge's, or Brave's) built-in developer mode, which is the same mechanism any Chromium browser offers for installing an extension from source rather than the store.

**Is it safe to install this way?**
Yes - "Load unpacked" just points your browser at a local folder of source files you downloaded yourself; nothing is hidden or compiled. The extension's own source is public, and it only ever sees an email address you explicitly typed or selected - no page content is read automatically.

**Does it cost anything?**
The extension itself is free. It uses your EMCHEQ API key, so checks draw from your account's existing plan the same way any other API call does - a free-plan key works for testing.

**What can it do?**
Type an address into the toolbar popup, or select one on any page and right-click "Verify with EMChEQ" - a result shows up as a desktop notification a few seconds later.
