Record a site's XHR into a HAR with Playwright, derive its private JSON API,
and call it directly over plain HTTP instead of browser-controlling the page
every time. Credit: trick by Jared Longster, popularized by Dax (thdxr).
- scripts/har_capture.py: Playwright HAR recorder with scripted --action steps
and embedded response bodies
- scripts/har_to_client.py: distills the HAR to endpoints (method/path template
/params/body/response) plus User-Agent+cookie+auth replay hints
- Validated live: derived + replayed the Algolia HN-search POST API and the
Wikipedia rest.php search-title GET, both browserless
- tests exercise the real derivation logic on a synthetic HAR fixture
optional-skills placement: heavy Playwright dependency, niche use case.
