Example use cases
SEO content length audit
“I want to check which emphasized text on https://mystore.com/features is the longest — can you rank all the em elements by text length, filtering by the class attribute set to 'feature-highlight', using 'feature' as the search term?”
Product description comparison
“Here's some HTML for my product page — can you rank the emphasized descriptions by text length, looking at the data-kind attribute with value 'desc', using 'product' as the term, and compare against these older descriptions: ['Legacy product blurb', 'Old short description']?”
Editorial emphasis length check
“Can you parse https://news-outlet.com/article and rank all the emphasized text segments by length, filtering for the id attribute value 'lead-em', with 'story' as the search term, so I can see which editorial emphasis is most prominent?”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-web-emphasis-rank?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to statically parse and rank emphasized HTML elements (e.g. <em> tags) by text length from a public webpage or raw HTML, with optional filtering by HTML attribute and comparison against historical text samples. Prefer this over general scraping endpoints when the specific goal is length-based ranking of emphasis-marked content.
Side effects
- URL is inaccessible or returns a non-200 HTTP status — parsing fails with no result
- HTML content exceeds 100,000 character limit — request rejected
- No emphasized elements matching the specified attribute and attribute_value found — empty or null ranking returned
- Term not found within any emphasized element — ranking may return zero-match result
- JavaScript-rendered content not parsed — dynamically loaded em elements will be missed
- previous_texts array exceeds 200 items — request rejected
