## When to prefer this

Choose this endpoint when you need to perform bigram/adjacent word-pair frequency analysis specifically scoped to HTML aside elements (sidebars, callout boxes, supplementary content blocks) on a static webpage or a provided HTML snippet. It is ideal for NLP tasks, content audits, or SEO analyses where you care about the co-occurrence of words in aside-specific content rather than the full page body. Not suitable for pages requiring JavaScript rendering, login, or dynamic content loading.

## Known failure modes

- URL is inaccessible, behind a paywall, or requires JavaScript rendering — only static HTML is parsed
- Aside element matching the given attribute/attribute_value not found — empty result returned
- HTML input exceeds 100,000 character limit — request rejected
- URL exceeds 2,048 character limit — request rejected
- No bigrams found for the specified term in the matching aside blocks — empty frequency result
- Malformed attribute pattern fails validation — request rejected
