Source Citation Freshness Checker

Check whether the text you quoted is still present on its source page. Supply one to three public HTTPS URLs and the excerpts you previously saved. Get a JSON report and a spreadsheet-ready CSV distinguishing matching excerpts, missing excerpts, HTTP errors and sources that could not be checked. Nothing is written to the source site.

Try the sample. The prefilled input checks “Example Domain” against its source. Replace the example with your own URLs and excerpts, start the Actor, then open Report and CSV downloads. Open OUTPUT for the complete report or download CITATIONS.csv. Each result includes the stored excerpt's SHA-256; successful fetches include the HTTP status, final URL, observation evidence and hashes of the body and extracted visible text. The run timestamp is UTC.

Status	What to do
excerpt-present	The normalized excerpt occurs on the page. This does not verify the meaning or accuracy of the claim.
review	The excerpt was absent. Review the source and any listed missing numbers before updating the quote.
http-error	The source returned an unsuccessful HTTP status. An error alone does not establish removal.
unverifiable	The source could not be compared, for example because of a timeout, blocked request, empty page or unsupported format.

Scope. HTML and plain text only. Whitespace and case are normalized. JavaScript is not run; scripts, styles and navigation are excluded. For plain-text responses, angle-bracket markup is treated as markup by the text extractor. No PDF/OCR, cookies, credentials, proxies or login. No automatic baseline changes. Use public URLs you are authorized to fetch; do not submit secrets in URLs or excerpts.

Limits. Up to 3 articles and 8,000 characters per excerpt; 128 KiB total input. Public DNS names only, HTTPS port 443, validated public addresses and IPv4 transport. Every redirect is rechecked (3 maximum). 12 seconds per distinct fetch including DNS and TLS, 1 MiB per response; compressed responses and unsupported encodings produce an unverifiable result. Fixed 256 MB; 60-second Actor timeout.

Price: $0.05 per Actor start, including platform usage, all checks and both exports. No per-URL or per-result charge. Set the maximum run cost to at least $0.05. Invalid inputs and runs where a source is unavailable still incur the start charge.

Apify stores your submitted input and generated reports under its storage access and retention settings. The checker does not persist fetched page bodies. For support, use the Actor Issues tab with a run ID and a non-sensitive example.
