How this service works
Forms — Structured extraction: Structured extraction 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 structured extraction result.
Output
A bounded structured extraction result containing the matched form element(s) from the page or supplied HTML, including the identified attributes, field names, and relevant metadata extracted via static HTML parsing (no JavaScript rendering).
Example use cases
Extract checkout form fields
“Go to https://shop.example.com/checkout and extract all the form fields — I want to find the form with id 'checkout-form' and get everything tagged with the 'name' attribute, so I can map out what the form collects.”
Audit contact form structure
“Here's some raw HTML from our contact page — can you parse it and extract all fields in the form with class 'contact' that have a 'required' attribute? I want to know what inputs are mandatory.”
Compare new form against known fields
“Scrape the signup form at https://app.example.com/register and look for the form element with id 'user-signup', pulling the 'placeholder' attribute values — I already know about 'Email' and 'Password' from last week, flag anything new.”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-web-forms-items?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to extract structured data specifically from HTML forms on a static, publicly accessible webpage or from directly supplied HTML. It is ideal for form auditing, field mapping, and web scraping of form structures without needing JavaScript execution. Prefer this over general-purpose scrapers when your target is form elements and their attributes specifically.
Side effects
