Problems first. The API only when it earns the place.
Every guide reproduces a real failure, shows the minimal do-it-yourself version, explains exactly where that version breaks and when it stays enough, and ends in a request executed against a fixture in CI.
8 guides · 2 focused clusters · dated verification
PDF and reporting
Browser-rendered documents, print CSS and repeatable report delivery.
Web capture engineering
Rendering arbitrary pages safely and operating browser jobs in production.
The output has blank image slots below the first fold, a sticky header repeated through the image, or a blank/truncated tail on a very tall document.
Intermittent 5xx responses around deploys and traffic spikes, with most of the request budget spent before `page.goto()` starts.
The page height is correct but image boxes below the fold are blank, low-resolution placeholders remain, or later list rows never exist in the DOM.
Production images wrap one word earlier than local output, use a system font, or shift between otherwise identical captures.
A public hostname reaches loopback, cloud metadata, RFC1918, Kubernetes service DNS or a custom storage/webhook endpoint that the caller could not access directly.
Two workers render the same request, the loser overwrites success with failure, a webhook fires twice, or usage contains a charge with no successful request left to justify it.
A confident annual-savings number whose result changes completely when one hidden engineering-hours assumption is made visible.
Code on these pages is re-executed against fixtures on a schedule. When a run fails or falls outside the re-execution window, the page stops claiming it was verified.
Who writes this, and what “verified” means
PageCapture Engineering writes each guide and the maintainer named on the article reviews it. Browser facts link to primary documentation; product limits link back to the public PageCapture contract.
The published request is normalized by the same contract as the API, generated snippets receive syntax checks, and the scheduled verification job executes them against controlled fixtures. The dated badge expires when that run falls outside the verification window.
