How this service works
Call when an agent needs select names via select[name] from a public page or HTML (SSRF-safe). Exact $0.004 USDC. Prefer unpaid POST /v1/sandbox/css-select-name first.
Output
Returns an array of 'name' attribute values extracted from all HTML elements on the page or HTML input that match the provided CSS selector.
Example use cases
Form field discovery from public page
“Go to https://checkout.example.com/payment and extract the name attributes of all input elements using the selector 'input' — I need to know what fields the form expects.”
Scrape select dropdown names from HTML
“I have this HTML snippet from a government form page — can you extract the name attribute of every select element in it using the CSS selector 'select'?”
Find hidden field names in a webpage
“Fetch https://app.acme.com/register and pull out all the name attributes from hidden inputs using the selector 'input[type=hidden]', so I can see what hidden parameters the form is submitting.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/css-select-name?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to extract 'name' attribute values from HTML elements on a public webpage or raw HTML using CSS selectors, especially when you want SSRF-safe remote fetching. Prefer the free unpaid POST /v1/sandbox/css-select-name first if available; fall back to this paid endpoint when the sandbox is unavailable or rate-limited. This is best for form analysis, scraping select/input field names, and lightweight DOM attribute extraction without spinning up a full browser.
Side effects
- URL is blocked, private, or returns a non-200 status — endpoint will return an error
- HTML input exceeds 200,000 character limit — request rejected
- SSRF-blocked URL (private IP ranges, localhost) — request denied for security reasons
- CSS selector syntax is invalid — parse error returned
- No elements matching the selector are found — empty array returned
- URL is malformed or too short/long — validation error
