Choose a working example, copy it into your Apify account and replace its public inputs.

• Hiring changes  — $0.01 per board check.
• Feed changes  — $0.005 per feed check.
• Migration redirects and broken links  — $0.002 per URL check.
• Sitemap changes  — $0.01 per document check.
• Robots.txt directives and sitemap discovery  — $0.005 per site check.

Inspect the first result, then repeat the same saved task to preserve monitor history. Schedule useful checks in Apify and consume their output through an integration or API. Use one concurrent run per monitor and deduplicate change event IDs.

Prices include platform usage. Successful unchanged checks and documented HTTP-error audit observations are charged. Set a maximum run charge and read OUTPUT as well as the dataset for errors or unchecked inputs.

Snapshot monitoring can miss intermediate changes. Job removals require two complete missing observations; sitemap absence does not prove page deletion.

I publish and maintain these independent paid utilities. See each Actor README for limits and use its issue tracker for reproducible bugs. Keep credentials and private data out of public issues.
