How this service works
Call when an agent needs data value attributes via data[value] from a public page or HTML (SSRF-safe). Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/css-data-value first.
Output
Returns an array or list of extracted string values found in data[value] attributes across elements on the specified page or within the provided HTML, parsed using an SSRF-safe server-side CSS selector engine.
Example use cases
Scrape product data attributes
“Pull all the data[value] attribute values from https://shop.example.com/catalog so I can see what product IDs are embedded in the page elements.”
Parse data values from raw HTML
“I have this HTML snippet from a dashboard widget — can you extract all data[value] fields from it for me?”
Audit data attributes on a public page
“Check https://mysite.com/listings and give me every data attribute value you find on elements using the data[value] selector — I want to see what metadata is baked into the markup.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/css-data-value?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to extract data[value] CSS attribute values from a public webpage or raw HTML without setting up your own scraper. Prefer the free /v1/sandbox/css-data-value endpoint first; fall back to this paid endpoint when sandbox access is unavailable or rate-limited. Choose this over generic CSS extraction endpoints when your target is specifically the data[value] attribute pattern.
Side effects
- URL is unreachable or returns non-200 status — extraction fails with an error
- HTML exceeds 200,000 character limit — request rejected
- No elements matching data[value] selector found — empty result returned
- SSRF-blocked URL (private IP range, localhost) — request rejected for safety
- Malformed URL (under 8 or over 2048 characters) — validation error
