How this service works
Button labels — Prior text-set comparison: Prior text-set comparison 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 prior text-set comparison result.
Output
Returns a bounded prior text-set comparison result indicating whether the current button label(s) found on the page or HTML match, partially match, or differ from the supplied previous_texts list, along with details about the matched attribute and term scope.
Example use cases
Detect CTA button copy regression
“I need to check if the checkout button on https://shop.example.com/cart still has the same label as before — compare the button with id 'checkout-btn' against these old labels: ['Proceed to Checkout', 'Buy Now'], using the term 'checkout'.”
Monitor landing page button changes
“Has the main CTA button on our landing page changed? Parse https://landing.example.com, look at the button with attribute 'data-role' set to 'primary-cta', search for the term 'start', and compare against our previous texts: ['Get Started', 'Start Free Trial'].”
QA test for button label consistency
“Run a comparison on this HTML snippet to check if the button with id 'submit-form' still matches any of these prior labels — ['Submit', 'Send', 'Confirm Order'] — using the term 'submit': <!doctype html><html><body><button id='submit-form'>Submit Order</button></body></html>”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-web-buttons-compare?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to detect whether button labels on a static HTML page have changed relative to a known prior set of text values, especially for regression testing, UI monitoring, or content auditing workflows. It is purpose-built for button-specific text comparison rather than general DOM diffing or full-page change detection.
Side effects
- URL is unreachable or returns non-200 status — parsing fails with error
- HTML exceeds 100,000 character limit — request rejected
- No button found matching specified attribute and attribute_value — empty result
- JavaScript-rendered buttons not visible — static parser only, dynamic content missed
- Invalid attribute pattern (must start with a letter, alphanumeric/dash/colon/underscore) — validation error
- previous_texts array exceeds 200 items — request rejected
