requiems-api-key: YOUR_API_KEYBuilt for Traffic Intelligence Workflows
From analytics to security — if you see HTTP requests, you need to know who's sending them.
Enrich analytics dashboards
Break down traffic by real browser and OS without relying on JavaScript. Works on server logs, API request headers, and CDN access logs.
Serve device-optimized content
Detect mobile, tablet, or desktop before rendering. Send lightweight pages to mobile clients without a client-side library.
Filter bot traffic
Identify crawlers, scrapers, and monitoring bots in your request stream. Exclude them from analytics or apply rate limiting per device class.
Detect suspicious sessions
Flag requests where the user agent doesn't match the declared device or browser. Useful for fraud detection and account protection workflows.
