Span API gives you a clean, programmable surface for inspecting requests, replaying traffic, and measuring latency across regions — without the boilerplate.
Structured views of headers, timing, TLS, and redirects for any endpoint.
Connect / TLS / TTFB breakdowns so you can see exactly where the time goes.
Re-run captured requests and diff the responses to catch regressions early.
