Example use cases
SEO content length benchmarking
“I want to check how the length of the article on https://blog.example.com/best-practices compares to my 5 older posts. The article is identified by the attribute 'class' with value 'post-body', and the term is 'guide'. Here are the previous texts from those older posts: ['Short overview', 'Detailed walkthrough with examples', 'In-depth tutorial covering all steps']. Give me a text length ranking.”
Competitor article length comparison
“Can you rank the text length of the article at https://competitor.com/review/product-x against these reference texts I've collected: ['Brief product summary', 'Full feature breakdown', 'Comprehensive user review']. The article element has attribute 'id' with value 'review-body' and the search term is 'review'.”
Content audit for CMS articles
“I have raw HTML for one of our product guides and I need to know where it ranks in text length compared to our existing articles. Here's the HTML: <!doctype html><html><body><article id='guide-1' data-kind='product'>Full product setup guide with all steps explained in detail.</article></body></html>. Use attribute 'id', value 'guide-1', term 'product', and compare against these previous texts: ['Quick start guide', 'Feature overview', 'Troubleshooting FAQ'].”

Side effects
- URL is inaccessible or returns non-200 status — no content to parse
- JavaScript-rendered content not available — static parser only, dynamic pages may return empty article
- Specified attribute/value combination not found in HTML — element match fails
- HTML or URL exceeds maximum allowed size (100KB HTML, 2048 char URL)
- previous_texts array is empty — ranking result may be trivial or undefined
- Invalid attribute pattern not matching regex — validation error returned
