How this service works
Articles — Duplicate value report: Duplicate value report for Articles. One public HTTPS page or supplied HTML; static parsing, no JavaScript rendering, login or access bypass. Specialised preset in a shared 50-profile, 20-operation engine. 0.01 USDC includes one bounded duplicate value report result.
Output
Returns a duplicate value report indicating which article attribute values on the page or in the supplied HTML match values already seen in the previous_texts list, effectively flagging repeated or conflicting attribute values among article elements.
Example use cases
Audit blog for duplicate article IDs
“Scan https://myblog.com/posts for any article elements that have duplicate 'id' attribute values, comparing against this list of IDs I've already seen: ['article-1', 'article-2', 'article-10'] — tell me if any new ones clash.”
Validate data-kind uniqueness across crawled pages
“I have this HTML snippet from a product catalog page and I need to check if any article element has a 'data-kind' attribute value of 'featured' that we've already used — previous values are ['featured', 'standard']. Can you run a duplicate check on it?”
Cross-page article deduplication for content team
“We're aggregating articles from multiple sources and I need to verify no duplicate 'data-id' attribute values appear. Check this URL https://news.example.com/latest against these already-collected values: ['nws-001', 'nws-002', 'nws-055'] and flag any repeats.”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-web-articles-duplicates?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to detect duplicate HTML attribute values (such as 'id', 'data-kind', or custom attributes) specifically within article elements on a static webpage or a supplied HTML fragment, especially when comparing against a known set of previously encountered values. It is best suited for content auditing pipelines, CMS deduplication checks, or multi-page crawl workflows where you accumulate a list of seen values and want to flag conflicts. Avoid it if you need JavaScript rendering, login-protected pages, or full-site crawling.
Side effects
- URL is unreachable or returns a non-200 response — endpoint cannot fetch the page
- HTML exceeds 100,000 character limit — request rejected
- Attribute name does not match the required pattern (must start with a letter, alphanumeric/colon/underscore/hyphen) — validation error
- URL and HTML both empty — no content to scan
- previous_texts list exceeds 200 items — request rejected
- Page requires JavaScript rendering — static parser will miss dynamically loaded articles
