How this service works
Call when an agent needs mark text extracted from a public page or HTML (SSRF-safe). Exact $0.009 USDC. Prefer unpaid POST /v1/sandbox/profile-mark first.
Output
Returns the extracted text content found within HTML <mark> elements from either a fetched public URL or provided raw HTML. The response contains the mark text strings found on the page, enabling downstream processing or analysis.
Example use cases
Highlighted text from research article
“Pull out all the highlighted (mark tag) text from this URL: https://papers.example.org/study-results — I want to see what the author emphasized.”
Mark extraction from raw HTML snippet
“I have this HTML from a product comparison page and I need you to extract all the text inside <mark> tags — here's the HTML: <html><body><p>This product is <mark>best in class</mark> for <mark>battery life</mark>.</p></body></html>”
Content audit for marked keywords
“Go to https://blog.example.com/seo-guide and pull out every piece of text that's wrapped in a mark element — I'm auditing what keywords they're emphasizing.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/profile-mark?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to extract specifically the text content of HTML <mark> (highlight) elements from a webpage or raw HTML. Prefer this over a general text extractor when you need only highlighted/marked content. Note: a free sandbox alternative at POST /v1/sandbox/profile-mark should be tried first before incurring the $0.009 USDC charge.
Side effects
- URL is unreachable or returns a non-200 status — extraction fails with an error
- SSRF-blocked URL (private IP ranges, localhost) — rejected for security reasons
- No <mark> elements present on the page — returns empty result
- HTML input exceeds 200,000 character limit — request rejected
- URL shorter than 8 characters or longer than 2048 characters — validation error
- Malformed HTML may result in incomplete or no extraction
