How this service works
Button labels — Empty value report: Empty value report for Button labels. 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 empty value report result.
Output
Returns a bounded report listing button elements on the parsed page or HTML where the specified attribute has an empty value, including contextual information about matched buttons relative to the search term and any previously seen texts provided.
Example use cases
Accessibility audit for missing button IDs
“Scan https://myshop.com/checkout and report any buttons where the 'id' attribute is empty — use 'checkout' as the search term so I know which buttons are missing proper identifiers.”
QA check on raw HTML for empty data attributes
“I have this HTML snippet: <button data-action="">Submit</button> — can you check which buttons have an empty 'data-action' attribute? Use 'submit' as the term.”
Regression test for button label changes
“Check https://app.example.com/dashboard for buttons where the 'aria-label' attribute is empty, using 'dashboard' as the term, and compare against these previously known texts: ['Settings', 'Logout', 'Home'].”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-web-buttons-empty?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, static parse of a single public webpage or HTML string to detect button elements with empty values for a specific attribute — particularly useful for QA, accessibility auditing, or regression testing of button markup. Prefer this over full browser automation when JavaScript rendering is not needed and cost efficiency matters at $0.01 per call.
Side effects
- URL is not publicly accessible or requires authentication — parsing will fail or return no results
- HTML exceeds 100,000 character limit — request will be rejected
- Invalid attribute name pattern (must start with a letter, max 50 chars) — validation error
- URL and HTML both omitted — no content to parse
- Attribute value string exceeds 200 characters — rejected
- Page uses JavaScript rendering for button content — static parser will miss dynamically injected buttons
