How this service works
Disclosure blocks — Structured extraction: Structured extraction for Disclosure blocks. 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 structured extraction result.
Output
A bounded structured extraction result containing the matched disclosure block's content and metadata — specifically the text or structured data found within the <details> element matching the given attribute, attribute value, and search term, filtered against previously seen texts.
Example use cases
FAQ accordion content extraction
“Pull out the disclosure block from https://docs.example.com/help that has the id 'returns-policy' and is about the topic 'returns' — I want the structured content from that details element.”
Product guide section parsing
“I have this HTML with a bunch of details tags — can you extract the one where the data-category attribute is 'installation' and the content relates to 'setup'? Here's the raw HTML: <!doctype html><html><body><details data-category="installation">Setup guide content</details></body></html>”
Deduplicating repeated crawl runs
“Go to https://company.com/disclosures and extract the disclosure block with id 'risk-factors' about the term 'risk', but skip any blocks whose text you've already returned like 'General Market Risk' and 'Liquidity Risk'.”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-web-details-items?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to extract structured content specifically from HTML <details>/<summary> disclosure blocks on a static, publicly accessible page, and you want to filter results by a specific HTML attribute (like id or data-*) and a keyword term. It is especially useful for deduplication across repeated crawls via the previous_texts parameter. Prefer it over generic scraping tools when the target content is in collapsible/disclosure HTML elements and you need a cheap, bounded, single-result extraction at $0.01 per call.
Side effects
- URL is not publicly accessible or requires authentication — no content returned
- Page uses JavaScript rendering to populate disclosure blocks — static parser returns empty results
- No <details> element matches the specified attribute and attribute value — empty or null result
- HTML content exceeds 100,000 character limit — request rejected
- Term or attribute value pattern does not match any element — empty extraction
- Invalid attribute name format (must start with a letter, max 50 chars) — validation error
