Web AI API Sniffing and Verification

Sniff Base URL and API Key on webpages and verify them instantly. Supports right-click menu quick check and automatic detection for specific sites.

Background

When browsing AI communities (e.g., Linux.do), GitHub Issues, or technical documentation, you often encounter shared test keys. The traditional approach is to copy the Base URL, copy the Key, open the extension, fill in the configuration, and click verify.

The Web AI API Sniffing feature simplifies this process into:

Select text → Right-click "Check AI API" → Test directly.
Or: On whitelisted sites, the extension automatically identifies the configuration on the page and pops up a prompt.

Core Capabilities

Select text containing a Base URL or API Key on any webpage, right-click, and select "Check AI API". The extension will attempt to extract valid interface information from the selected text (or clipboard) and pop up a test overlay within the current page.

2. Automatic Sniffing (Auto Detect)

On specific whitelisted sites (e.g., linux.do), when you open a post containing a large number of keys, the extension will automatically scan the page content.

If a likely valid Base URL + Key combination is extracted, a lightweight prompt will pop up in the upper right corner of the page.
Click the prompt to open the test dialog.

3. In-page Test Dialog

Perform the following operations without leaving the current webpage:

Automatic Extraction: Automatically separate Base URL, Secret Key, and API Type from the source text.
Instant Testing: Click "Start Test" to verify the connectivity of the key and available models.
Get Model List: Fetch the full list of model IDs supported by the upstream site with one click.
Save to Credentials: Once verified, save it with one click to the extension's API Credentials for later export to tools like CherryStudio.

Configuration and Customization

Navigate to Settings → Basic Settings → Web AI API Check to configure the following:

1. Basic Switches

Right-Click Menu: Whether to show "Check AI API" in the browser's right-click menu.
Auto Detect: Whether to enable background automatic scanning on matching sites.

2. Site Whitelist (URL Whitelist)

You can customize which sites the extension is allowed to automatically sniff.

Supports Regular Expression (RegExp) matching (case-insensitive).
Default Configuration: Usually includes built-in matching rules for common AI forums and communities.
Example: Enter linux\.do to match all pages on that forum.

Privacy and Security

Local Extraction: The sniffing and extraction process is executed entirely locally in your browser.
Privacy Protection: The extension does not automatically upload detected text to any server; API requests are only sent according to the Base URL you fill in when you click "Start Test".
Silent Scanning: The automatic detection process is extremely lightweight and does not affect the scrolling or loading performance of the webpage.
