How this service works
Unordered lists — Invisible character flags: Invisible character flags for Unordered lists. 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 which unordered list items contain invisible or hidden Unicode characters, flagged against the provided search term and optional HTML attribute filter. Output identifies specific characters or positions where anomalies are detected within the list.
Example use cases
Audit product listing for hidden characters
“Scan the unordered list with id 'product-list' on https://shop.example.com/catalog for any invisible unicode characters in list items mentioning 'subscription' — I want to know if anything sketchy is hidden in the text.”
Validate scraped HTML for unicode anomalies
“Here's some HTML with a ul element — check it for invisible character flags in any list items containing the word 'terms', focusing on the element with attribute id equal to 'legal-list'.”
Content integrity check before publishing
“Before we publish, can you run this HTML snippet through an invisible character detector for the unordered list with id 'faq-items'? Search for 'answer' and flag any hidden unicode or zero-width characters lurking in the li elements.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-web-unordered-lists-unicode?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to detect hidden or invisible Unicode characters specifically within HTML unordered list elements, either from a live URL or a raw HTML string. It is ideal for content integrity auditing, detecting steganographic text, or validating scraped list data before downstream processing. Prefer it over general text analyzers when your target data is structured as HTML bullet lists and you need a specialized preset tuned for Unicode flag detection.
Side effects
- URL is unreachable or returns non-200 status — parsing fails with no content
- HTML exceeds 100,000 character limit — request rejected
- JavaScript-rendered content not available since only static HTML is parsed
- Invalid attribute name pattern causes schema validation error
- No matching ul element found for given attribute/value pair — empty result
- Term string too short (below minLength of 1) causes validation error
