How this service works
Textarea defaults — Duplicate attribute values: Duplicate attribute values for Textarea defaults. 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 attribute values result.
Output
Returns a bounded result set identifying textarea elements in the provided HTML (or fetched URL) whose specified attribute contains the given attribute value in duplicate, filtered by the search term and excluding any previously recorded text strings. The response includes one duplicate attribute values result per call.
Example use cases
Audit form page for duplicate IDs
“Scan https://myapp.com/checkout for any textarea elements that share the same 'id' attribute value of 'comments' — flag any duplicates and filter for ones mentioning 'order'.”
Validate pasted HTML snippet
“Here's some HTML I wrote — can you check it for textareas that have duplicate 'data-kind' attribute values matching 'feedback'? The term I care about is 'survey'. Here's the HTML: <!doctype html><html><body><textarea data-kind="feedback">Survey one</textarea><textarea data-kind="feedback">Survey two</textarea></body></html>”
Incremental duplicate detection across crawls
“Re-check https://docs.mysite.com/editor for textareas with duplicate 'name' attribute values of 'notes', filtering for the term 'draft', and exclude these previously seen texts: ['Old draft text', 'Earlier notes entry'].”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-web-textareas-attribute-duplicates?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to statically audit HTML (from a URL or raw snippet) specifically for duplicate attribute values on textarea elements — particularly useful for form validation, accessibility audits, or QA pipelines where duplicate IDs or data attributes on textareas would cause bugs. Choose this over generic HTML validators when you need targeted textarea-scoped attribute deduplication with term filtering and incremental deduplication via previous_texts.
Side effects
- URL is unreachable or returns non-200 status — no HTML to parse
- Provided HTML exceeds 100,000 character limit — request rejected
- Attribute name does not match pattern ^[a-zA-Z][a-zA-Z0-9:_-]{0,49}$ — validation error
- Term is empty or missing — minLength violation
- No textareas found in HTML — empty result set
- Duplicate attribute values not found for specified attribute/value combination — empty result
- Payment not processed — x402 payment required error
