Description from store
The TCVS Secure Connector solves cross-origin resource sharing (CORS) issues when accessing the U.S. Treasury's Check Verification Service API from credit union web applications.
**Key Features:**
• Adds required CORS headers for Treasury API access
• User-controlled permission system - you decide which sites can use it
• Works with Corelation Keystone and other credit union platforms
• Modern, secure Manifest V3 architecture
• Real-time request statistics and connection testing
• No content injection - uses secure message passing
**How it works:**
1. Install the extension
2. Navigate to your credit union application
3. Click the extension icon to grant permission for that specific domain
4. The extension will securely proxy requests to the Treasury API
**Security First:**
- Only modifies headers for tcvs.fiscal.treasury.gov
- Requires explicit permission for each domain
- No data collection or tracking
- Open source and transparent
Perfect for credit unions and financial institutions that need reliable access to Treasury check verification services.
