Labs

Experiments you can replay.

Each lab is run once against the live APIs and recorded — every request, every response, every millisecond. What you open here is that recording, replayed. No key on this site, no live calls, and every visitor sees the same evidence.

1 · Record — Run live against the real APIs, once.
2 · Commit — The recording is a file in the repo. Never edited.
3 · Replay — This page plays it back at recorded speed.
