How this service works
Forms — Duplicate value report: Duplicate value report for Forms. 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
A bounded duplicate value report identifying which form elements on the page or in the supplied HTML share the same value for the specified attribute, including any matches against previously known values, scoped to the given search term.
Example use cases
Audit form IDs on live page
“Scan https://mysite.com/register for any duplicate 'id' attribute values inside forms — the term to focus on is 'register' and I want to know if anything collides with the existing value 'user-form'.”
Validate supplied HTML for duplicate names
“I've got this HTML snippet with a multi-field form — can you check it for any duplicate 'name' attribute values related to 'payment', and flag any that repeat the value 'card-number'?”
Cross-check form attributes against known list
“Look at https://app.example.com/profile/edit for duplicate 'data-field' attributes matching the term 'profile', and compare against these previously seen values: 'profile-name', 'profile-email' — tell me which ones are duplicated.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-web-forms-duplicates?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, static-parse check for duplicate attribute values within HTML forms on a single page — ideal for CI/CD form audits, accessibility checks, or pre-submission HTML validation where JavaScript rendering is not required and cost must be minimal ($0.01 per check).
Side effects
- URL is unreachable or returns a non-200 status — no form data extracted
- Page requires JavaScript rendering — static parser returns incomplete or empty form structure
- HTML input exceeds 100,000 character limit — request rejected
- Attribute pattern does not match schema regex — validation error returned
- No forms found on the page — empty report returned
- term or attribute_value parameters too long — truncation or rejection
