How this service works
Page change check: content hash, clean text and line diff: Fetches one public page and returns a SHA-256 hash of its main text plus the clean text; if you send the previous hash or text it also says changed yes/no and, with previous text, lists added and removed lines. Input: url, optional previous_
Output
Returns a JSON object containing the canonical URL fetched, HTTP status code, a SHA-256 hash of the page's extracted main text, the clean text itself, a boolean `changed` flag (null if no previous hash/text was supplied), a `compared_with` field indicating what was compared against, and optionally a `diff` object listing added and removed lines. Also includes `text_truncated` if the text was cut off.
Example use cases
Competitor pricing page monitor
“Fetch https://competitor.com/pricing and compare it to this previous text I saved last week — tell me exactly which lines were added or removed so I know what changed.”
Documentation update tracker
“Check https://docs.myframework.io/changelog and see if it's changed since this hash: e4a2d1c3b5f6789012345678901234567890abcdef1234567890abcdef123456 — I want to know if there's new content.”
Content integrity verification
“Grab the main text from https://mypublished-article.com/post/123 and give me its SHA-256 hash so I can verify nothing has been altered since I published it.”
Technical details
Endpoint
GEThttps://shop.lordevo.com/api/quick/page-diff?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need lightweight, recurring page change detection without running a full browser or crawler. It is ideal for monitoring specific public pages (documentation, pricing, news, status pages) where you want a stable content hash for comparison across polling intervals. Prefer it over full SEO audit endpoints when you only care about content changes, not technical SEO signals. It is well-suited for agents that poll on a schedule and need to decide whether to take action only when content actually changes.
Side effects
- URL is unreachable or returns non-200 status — endpoint may still return hash/text of error page or report failure
- Invalid previous_hash format (not 64 hex chars) causes schema validation error
- Page has no extractable main text — returns empty or minimal text with valid hash
- Very long previous_text may be truncated at 200,000 character limit
- Private/intranet URLs return no content or access denied
- Rate limiting or payment failures result in 402 or 429 responses
