How this service works
Call when an agent needs type attributes of //input via //input/@type from a public page or HTML (SSRF-safe). Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/xpath-input-type first.
Output
A list of `type` attribute values from all `<input>` elements found on the page or in the provided HTML, such as ['text', 'email', 'password', 'hidden', 'submit']. Returns an empty list if no input elements or type attributes are found.
Example use cases
Analyzing login form field types
“Look at https://accounts.mysite.com/login and tell me what input types are used in the form — I want to know if there's a password field, a hidden field, or anything unusual.”
Auditing form accessibility by input types
“I have this HTML snippet for a checkout form and I need to know all the input type values in it — can you extract them so I can check if the right input types are being used for accessibility?”
Detecting hidden inputs on a competitor page
“Go to https://shop.competitor.com/checkout and extract all the input type attributes — I want to see if they're using hidden fields or any non-standard input types in their checkout flow.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/xpath-input-type?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to enumerate the `type` attributes of `<input>` elements on a public page or HTML blob via XPath. It is SSRF-safe and costs only $0.001 USDC per call. Prefer the free sandbox POST /v1/sandbox/xpath-input-type when available. Choose this over generic HTML scrapers when you need a targeted, low-cost extraction of just input type attributes without parsing full DOM structures.
Side effects
- URL is unreachable or returns a non-200 status — extraction fails with an error
- SSRF-blocked URLs (private IP ranges, localhost) are rejected for security
- HTML exceeds 200,000 character limit — request rejected
- Page has no <input> elements or none have a type attribute — returns empty result
- Malformed HTML may result in incomplete or empty extraction
- URL shorter than 8 characters or longer than 2048 characters rejected by schema validation
