Example use cases
Tracking product name length prominence

Auditing headline emphasis on article pages

Monitoring competitor bold CTA text changes
“Check https://competitor.com/landing and tell me how the bold call-to-action text ranks by length — look for the term 'buy', filter by attribute 'class' with value 'cta', and measure it against these prior versions: 'Buy now and save', 'Limited time offer'.”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-web-strong-rank?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, low-cost static parse of <strong>/<b> emphasis elements on a public webpage to rank their text by character length, especially when tracking how a specific element's text length changes over time relative to a history of previous values. Prefer it over full DOM analysis tools when JavaScript rendering is not needed and you only care about bold/strong text length ordering.
Side effects

- No <strong> elements found matching the specified attribute/term — empty result
- JavaScript-rendered content not available since only static parsing is used
- Term string too short (below minLength of 1) or too long (above 100 characters) — validation error
