About API Monitoring
API Monitoring is a powerful developer tool for capturing and analyzing API calls made by any website.
FEATURES:
• Real-time API call monitoring with start/stop control
• Captures full request and response data
• Records HTTP method, URL, status code, and response time
• Configurable URL patterns to filter which APIs to capture
• One-click CSV export for data analysis
• Works on any website
HOW TO USE:
1. Click the extension icon
2. Enter URL patterns to monitor (e.g., "api", "graphql")
3. Click "Start" to begin monitoring
4. Browse the website - all matching API calls will be captured
5. Click "Export CSV" to download captured data
PERFECT FOR:
• Developers debugging API integrations
• QA teams testing web applications
• Performance analysis and optimization
• Understanding how websites communicate with backends
PRIVACY:
All captured data is stored locally on your device. No data is transmitted to external servers. Monitoring only runs when you explicitly enable it.
This extension requires broad permissions to intercept network requests, but only captures data you choose to monitor.
