How this service works
Call when an agent needs input types via input[type] from a public page or HTML (SSRF-safe). Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/css-input-type first.
Output
A list of distinct or all input[type] attribute values found in the page or HTML, such as 'text', 'email', 'password', 'hidden', 'checkbox', 'radio', 'submit', etc., parsed from input elements via CSS selector matching.
Example use cases
Auditing form field types on a login page
“Check https://app.acme.com/login and tell me all the input types used on that page — I want to see if they're using password and hidden fields correctly.”
Analyzing competitor signup form structure
“Go to https://competitor.io/register and extract every input[type] value from the HTML so I can understand how their signup form is structured.”
Validating form inputs from raw HTML
“I have this HTML snippet from our checkout page — can you pull out all the input[type] values so I can verify we have the right field types before we go live?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/css-input-type?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically extract input[type] values from a live public URL or raw HTML and want SSRF protection built in. Prefer the free POST /v1/sandbox/css-input-type endpoint first if available. Choose this over general-purpose HTML scrapers when you specifically need input element type enumeration without running your own browser or parser.
Side effects
- URL is private/internal (SSRF-blocked) — returns error rejecting non-public addresses
- URL is unreachable or returns non-200 — fetch failure error
- HTML exceeds 200,000 character limit — payload too large error
- URL string shorter than 8 characters — validation error
- No input elements found — returns empty list
- Malformed HTML — parser may return partial or empty results
