Audit aside blocks for missing IDs

Validate aside attributes in pasted HTML

Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-web-asides-empty?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, static-parse audit of HTML aside elements for empty or missing attribute values — particularly when you don't need JavaScript rendering and want a cheap, fast check ($0.01 USDC). Prefer this over a full DOM-rendering scraper when the target page delivers aside blocks in raw HTML and you only need attribute emptiness analysis, not full content extraction.
Side effects
- URL is unreachable or returns a non-200 HTTP status
- HTML payload exceeds 100,000 character limit
- Attribute name does not match pattern (must start with a letter, alphanumeric/colon/underscore/hyphen only)
- No aside blocks found on the page
- Page requires JavaScript rendering (not supported — static parsing only)
- Login-gated or access-restricted pages cannot be parsed
- Term parameter missing or below minimum length of 1
