How this service works
Page titles — Attribute presence check: Attribute presence check for Page titles. One public HTTPS page or supplied HTML; static parsing, no JavaScript rendering, login or access bypass. Specialised preset in a shared 50-profile, 20-operation engine. 0.01 USDC includes one bounded attribute presence check result.
Output
Returns a bounded attribute presence check result indicating whether the specified HTML attribute (and optionally its exact value) exists on the page title element parsed from the provided URL or raw HTML, using static parsing only with no JavaScript execution.
Example use cases
SEO title attribute audit
“Check if the page title on https://shop.acme.com/home has a 'class' attribute set — I want to confirm it's there without running any JavaScript.”
Verify title ID in raw HTML
“I have this HTML snippet: <title id="hero">Welcome to our store</title> — can you confirm the 'id' attribute is present on the title element and that its value is 'hero'?”
QA check for CMS-generated pages
“For the page at https://blog.mybrand.com/post-123, check whether the title tag has a 'data-tracking' attribute — I'm auditing our CMS output to make sure it's tagging titles correctly.”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-web-title-attribute-presence?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, static check of whether a specific HTML attribute exists on a page's title element — ideal for SEO auditing, CMS output validation, or QA pipelines where JavaScript rendering is unnecessary and cost must be kept minimal ($0.01/call). Prefer it over full-page scrapers or headless browser tools when only the title tag attribute matters.
Side effects
- URL is inaccessible, behind a login, or returns a non-200 status — check cannot be performed
- Provided HTML exceeds 100,000 character limit — request rejected
- Attribute name does not match the required pattern (must start with a letter, max 50 chars) — validation error
- URL and HTML both omitted or empty — ambiguous input error
- Term parameter missing or empty (minLength 1) — request rejected
- Page title element not found in parsed HTML — attribute check returns absent
