How this service works
Time labels — Invisible character flags: Invisible character flags for Time labels. 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 invisible character flags result.
Output
Returns a bounded result indicating whether invisible Unicode characters were found within the targeted <time> element(s), including flags identifying the specific invisible characters detected and their positions within the label text.
Example use cases
Audit timestamps for unicode injection
“Scan https://shop.example.com/blog/post-123 for invisible unicode characters inside its <time> tags — specifically the one with attribute data-kind and value 'published', and compare against these previous texts: 'March 2024', 'April 2024'.”
Verify supplied HTML time labels
“I have some raw HTML — can you check its <time> element with id 'release-date' for any invisible or zero-width Unicode characters hiding in the label text? The term to look for is 'release'.”
Content integrity check on product pages
“Flag any invisible unicode characters in the time labels on https://marketplace.example.com/listings, especially the <time> tag with attribute 'class' and value 'listing-date', using 'listing' as the search term.”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-web-times-unicode?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need to detect invisible or zero-width Unicode characters embedded in HTML <time> elements, such as for security audits, content integrity checks, or detecting unicode steganography in timestamps. It is distinct from general text unicode scanners because it targets the <time> HTML element specifically and can accept either a live URL or raw HTML.
Side effects
- URL is inaccessible or returns non-200 status — parsing fails with no content
- HTML does not contain any <time> elements matching the specified attribute/value — empty result
- JavaScript-rendered time labels not visible due to static-only parsing
- attribute value or term mismatch results in no matched elements
- HTML payload exceeds 100,000 character limit — request rejected
- Malformed HTML prevents reliable parsing
