How this service works
Call when an agent needs aria-label values via [aria-label] from a public page or HTML (SSRF-safe). Exact $0.007 USDC. Prefer unpaid POST /v1/sandbox/css-aria-label first.
Output
A list of all aria-label attribute values found in the page or HTML, extracted via the CSS [aria-label] selector. Returns matched values as strings, enabling downstream accessibility auditing or UI analysis.
Example use cases
Accessibility audit of a live page
“Fetch all aria-label attributes from https://myapp.example.com/dashboard so I can check if our accessible names are set correctly.”
Extracting nav labels from raw HTML
“Here's the HTML of a page I scraped — can you pull out every aria-label value from it so I know what screen-reader labels are present?”
Comparing aria labels across pages
“Get the aria-label values from https://competitor.example.com/pricing — I want to compare how they label their interactive elements.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/css-aria-label?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically extract aria-label accessibility attribute values from either a live public webpage (by URL) or raw HTML. Prefer it over general-purpose scraping tools when the specific goal is accessibility label extraction. Note the description recommends trying the free POST /v1/sandbox/css-aria-label endpoint first before paying $0.007 USDC for this one.
Side effects
- URL is unreachable or returns non-200 status — extraction fails with network error
- SSRF-blocked URL (private IP range, localhost) — rejected for security reasons
- HTML input exceeds 200,000 character limit — request rejected
- No aria-label attributes present in the page — returns empty result set
- Malformed HTML that prevents CSS selector parsing — may return partial or empty results
- URL missing or both url and html omitted — validation error
