Example use cases
Product guide section indexing

Extracting FAQ sub-items from HTML
“I have this HTML page — can you extract all H6 tags that contain the word 'answer' and have a class attribute value of 'faq-item'? Here's the raw HTML: <!doctype html><html><body><h6 class="faq-item">What is the answer to your pricing question?</h6></body></html>”
Deduplicating repeated headings across crawls
“Extract H6 headings containing 'feature' from https://company.com/features, and skip any headings whose text matches these previously seen ones: 'Feature Overview', 'Feature Comparison'.”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-web-h6-items?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to extract specifically H6 (level-six) heading elements from a static, publicly accessible webpage or provided HTML snippet, filtered by keyword and/or attribute. Prefer this over general-purpose scrapers when you only need H6 elements and want a structured, pre-parsed result at low cost. Not suitable for pages requiring JavaScript rendering, authentication, or when you need headings of other levels (H1–H5).
Side effects
- URL is inaccessible, behind a login wall, or requires JavaScript rendering — endpoint only does static parsing
- HTML exceeds 100,000 character limit causing rejection
- Term parameter missing or below minimum length of 1 character
- Attribute name does not match the required pattern (must start with a letter, alphanumeric/colon/underscore/hyphen)
- No matching H6 elements found returns an empty result set
- URL returns a non-HTML content type
- Payment of 0.01 USDC not fulfilled via x402 protocol results in 402 response
