How this service works
Table captions — Duplicate attribute values: Duplicate attribute values for Table captions. 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 listing table caption elements in the HTML where the specified attribute carries a duplicate value, including the repeated attribute value, the matching caption texts, and any overlap with previously seen texts provided in the request.
Example use cases
Audit HTML report for duplicate caption IDs
“Scan https://myreports.example.com/annual for table captions that have duplicate 'id' attribute values — flag any caption that reuses an id already seen elsewhere on the page.”
Validate accessibility in raw HTML upload
“Here's my raw HTML — check all the table <caption> elements for any that share the same 'class' attribute value, specifically looking for duplicates of 'highlight'.”
QA check on product guide page
“Look at https://docs.example.com/products and tell me if any table captions have duplicate 'data-section' attributes with the value 'product' — I want to catch any repeated labels before publishing.”

Endpoint

Choose this endpoint when you need a lightweight, static-parse audit of HTML table caption elements specifically for duplicate attribute values — particularly useful for accessibility audits, HTML validation pipelines, or pre-publish QA checks where you want to catch repeated id, class, or custom attributes on caption tags without needing JavaScript rendering or full browser execution.
Side effects
- URL is inaccessible or returns a non-200 status, causing no content to be parsed
- HTML exceeds 100,000 character limit, triggering a rejection
- Attribute name does not match the required pattern (must start with a letter, max 50 chars)
- No table captions exist in the provided HTML, resulting in an empty result
- JavaScript-rendered captions are not detected since only static HTML is parsed
- Invalid URL format causes immediate input validation failure
