How this service works
Table captions — Word frequency: Word frequency for Table captions. 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 word frequency result.
Output
Returns a bounded word frequency result showing how often the specified term (or all words) appear within HTML table caption elements extracted from the provided URL or HTML content, optionally scoped to a specific attribute/value pair on the caption element.
Example use cases
Audit table caption terminology on product page
“Can you count how many times the word 'price' appears in table captions on https://shop.example.com/products? Look at captions with the 'class' attribute set to 'summary'.”
Validate keyword consistency in report HTML
“I have this HTML report and I want to know how frequently the term 'revenue' shows up in its table captions — here's the raw HTML. Also check against these previous caption texts: ['Q1 revenue summary', 'Annual revenue overview'].”
Monitor terminology drift in generated documents
“Check this HTML document for how often 'delivery' appears in its table captions — I want to compare it against these older caption texts I've been tracking: ['Past delivery stats', 'Delivery performance 2023'].”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-web-captions-words?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need static HTML parsing of table caption elements specifically for word frequency analysis. It is purpose-built for the <caption> tag scope, unlike general full-page word frequency tools. Ideal when you have a public HTTPS URL or raw HTML and want lightweight, low-cost ($0.01 USDC) term counting without JavaScript rendering or authentication.
Side effects
- URL unreachable or returns non-200 status — parsing fails with no caption data
- No table caption elements found in the HTML — empty frequency result returned
- JavaScript-rendered captions not present in static HTML — missing content
- Term not found in any caption — zero-count result
- HTML exceeds 100,000 character limit — request rejected
- Invalid attribute name pattern — schema validation error
- URL exceeds 2048 character limit — request rejected
