How this service works
Call when an agent needs label text extracted from a public page or HTML (SSRF-safe). Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/profile-label first.
Output
Returns the text content of all HTML <label> elements found in the page at the given URL or within the provided HTML string. Typically a list or concatenated text of label values extracted from the document.
Example use cases
Audit form accessibility labels
“Pull all the label element text from https://app.mysite.com/register so I can check if our form inputs are properly labeled for accessibility.”
Scrape competitor form field names
“Extract the label text from this raw HTML I have from a competitor's checkout page — I want to see what fields they're collecting from users.”
Auto-fill schema from live page
“Fetch https://portal.example.com/onboarding and give me all the label text so I can map their form fields to our internal data schema.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/profile-label?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to extract specifically <label> element text from a public webpage or a raw HTML snippet without spinning up a full browser. Prefer the free sandbox endpoint (/v1/sandbox/profile-label) first for testing. Choose this over generic HTML parsers when you want a managed, SSRF-safe extraction service that handles fetching and parsing in one step for $0.003 USDC per call.
Side effects
- URL is not publicly accessible or returns a non-200 status — extraction fails
- SSRF-blocked URL (private IP ranges, internal hosts) — request rejected for security
- HTML input exceeds 200,000 character limit — validation error
- No label elements found in the page — empty result returned
- Malformed URL (under 8 characters or invalid format) — input validation error
- Page requires JavaScript rendering — static extraction may miss dynamically inserted labels
