How this service works
Measure website response latency, payload size, compression, caching, and performance signals for a public URL.
Output
Returns structured metrics including response timing (e.g. TTFB, total duration), response payload size (raw and compressed), compression encoding used (e.g. gzip, brotli, none), and cache-related HTTP headers (e.g. Cache-Control, ETag, Expires).
Example use cases
API endpoint latency audit
“Profile the response timing and payload size for https://api.myshop.com/products — I want to know how fast it responds and whether it's using compression.”
CDN cache verification
“Check if https://cdn.mybrand.com/assets/main.js is being served with proper cache headers and whether the response is compressed.”
Pre-launch performance baseline
“Run a performance profile on https://staging.myapp.com/v2/home so I can see response time, payload size, and compression before we go live.”
Technical details
Endpoint
POSThttps://apiacre.com/v1/web/performance-profileWhen to prefer
Choose this endpoint when you need objective, server-side HTTP performance measurements for a specific URL — including timing, size, compression, and caching — rather than browser-based or synthetic frontend metrics. It is especially useful for auditing API endpoints, verifying CDN behavior, or establishing performance baselines without running your own infrastructure.
Side effects
- Target URL is unreachable or returns a non-200 status — endpoint may return an error with the HTTP status code received
- Invalid or malformed URL input — returns a validation error
- Target server takes too long to respond causing a timeout
- URL points to a non-HTTP resource or unsupported protocol
- Rate limiting or firewall on the target server blocks the profiling request
