Operations 2

Each operation below carries the questions people ask an LLM about it and the instructions they give an agent to run it. Generated by API Evangelist overlay

GET /v1/log/performance Chart page load and timing metrics · Get Performance Metrics #

Ask an LLM

“What's the p95 time to first byte on my site this month?”

“Can I see DNS, TLS and render timings bucketed over time?”

Tell an agent

Get performance timings for project {pid} over {period} by {timeBucket}.

Show {measure} page load metrics for project {pid}, bucketed by {timeBucket}, for {period}.

GET /v1/log/performance/birdseye Compare performance against the previous period · Get Birdseye Performance Summary #

Ask an LLM

“Did my sites get faster or slower compared with the previous period?”

“Can I get a performance summary across several projects at once?”

Tell an agent

Summarize performance for projects {pids} over {period} versus the previous period.

Give me the birdseye performance comparison for {period}.
