How this service works

Specialised preset in a shared 50-profile, 20-operation engine. 0.01 USDC includes one bounded distinct value extraction result.

Example use cases
Audit form labels on a product page
“Go to https://shop.example.com/checkout and extract all the unique 'id' attribute values from label elements that include the word 'shipping' — I want to know what distinct label ids are used without any duplicates.”
Extract label texts from supplied HTML
“I have this HTML snippet from a registration form — can you parse it and give me all the distinct label texts that contain the word 'email', looking at the 'data-kind' attribute? Here's the HTML: <!doctype html><html><body><label data-kind="required">Email address</label><label data-kind="optional">Backup email</label></body></html>”
Inventory unique labels across a form builder
“Fetch https://forms.example.com/builder and list all the unique 'name' attribute values on label elements that include the word 'field', skipping anything already in my list: 'First name', 'Last name'.”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-web-labels-unique?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to enumerate distinct or unique values from HTML label elements on a static, publicly accessible webpage or a supplied HTML snippet. It is ideal for auditing form structures, inventorying label attributes, or deduplicating label data without needing JavaScript rendering or authentication bypass. Prefer it over general-purpose scrapers when your target is specifically form label elements and deduplication is required.
Side effects
- URL is inaccessible, private, or requires login — static parser cannot bypass authentication
- JavaScript-rendered content is not parsed — dynamically injected labels will be missing
- No matching label elements found — returns empty result set
- HTML input exceeds 100,000 character limit — request rejected
- Attribute name does not match pattern — validation error returned
- Search term is empty or missing — minimum length violation
