How this service works
Table head groups — Term context excerpts: Term context excerpts for Table head groups. 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 term context excerpts result.
Output
Returns bounded context excerpts — surrounding text snippets — for occurrences of the specified search term found within HTML table head group elements (<thead>) on the given page or HTML payload. Results are filtered by optional attribute/attribute-value targeting and de-duplicated against any previously seen texts.
Example use cases
Audit table headers for terminology
“I have this HTML page at https://docs.example.com/data-dictionary and I need to find all the table header groups that mention the term 'nullable' — can you pull out context snippets around each occurrence?”
Verify term presence in specific thead
“Check this HTML I'm pasting — look inside the thead element with id 'summary' and find any context excerpts where the word 'gross' appears: <!doctype html><html><body><table><thead id='summary'><tr><td>Gross margin overview</td></tr></thead></table></body></html>”
Deduplicate term excerpts across crawls
“I've already seen these header snippets from a previous crawl: ['Total revenue Q1', 'Revenue breakdown']. Now fetch https://reports.example.com/annual and find new context excerpts around the term 'revenue' in table head groups that I haven't seen yet.”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-web-table-heads-contexts?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to find where a specific term appears within HTML table header groups (<thead>) and want surrounding context excerpts rather than full page text. Ideal for auditing data dictionaries, verifying column header terminology, or monitoring how specific terms are used in structured tabular content on web pages. Prefer this over general full-page text extractors when your target is specifically table header context.
Side effects
- URL is inaccessible or returns a non-200 status, resulting in no content to parse
- Term not found in any table head group, returning empty excerpt list
- HTML payload too large (exceeds 100,000 characters), causing rejection
- Search term shorter than 1 character or longer than 100 characters fails validation
- Attribute pattern does not match expected format (must start with a letter, alphanumeric/colon/underscore/dash)
- Page requires JavaScript rendering which is not supported — static parsing only
- Login-protected or paywalled pages cannot be accessed
