How this service works
Canonical URL declarations — Word frequency: Word frequency for Canonical URL declarations. 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 a specified term (or all words) appear within the canonical URL declaration text found in the parsed HTML page. The result is derived from static HTML parsing with no JavaScript rendering, covering one page or HTML snippet per call.
Example use cases
SEO canonical tag keyword audit
“Go to https://www.mybrand.com/landing and count how many times the word 'sale' appears across its canonical URL declarations — check the element with id 'main-canonical' and compare against my previous page versions: ['Old landing text', 'Draft version'].”
HTML snippet canonical word check
“I have this HTML: <!doctype html><html><head></head><body><link rel="canonical" href="https://store.example.com/shoes" id="canon1"></body></html> — can you count how many times 'shoes' appears in the canonical declarations, checking the attribute id with value 'canon1'?”
Competitor canonical URL term frequency
“Analyze https://www.competitorsite.com/blog and tell me how frequently the term 'guide' shows up in their canonical URL declarations — look at the href attribute and compare against ['Previous competitor text'].”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-web-canonical-words?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, cheap ($0.01 USDC) static word frequency analysis specifically scoped to canonical URL link declarations in HTML. It is ideal for SEO audits of canonical tags, lightweight keyword density checks on canonical hrefs, or batch-style programmatic checks where JavaScript rendering is not needed. Prefer it over general web scrapers when the target is specifically canonical link elements rather than full page body text.
Side effects
- URL is unreachable or returns a non-200 status — no content to parse
- HTML exceeds 100,000 character limit — request rejected
- Specified attribute or attribute_value does not match any canonical element — empty or zero result
- URL requires JavaScript rendering or login — static parser returns incomplete content
- Term not found in canonical declarations — returns zero frequency
- Invalid attribute pattern not matching regex — schema validation error
