How this service works
Does a page contain a phrase? Fetches the page and searches its readable text (case-insensitive) for the phrase you give, returning found/not found with a snippet of context and the match count. Stock alerts, price wording, 'sold out' checks and content verification. $0.01 per check.
Output
Returns a boolean found/not-found status, the number of times the phrase appears on the page, and a short snippet of surrounding text providing context for where the match occurred.
Example use cases
Stock alert for e-commerce product
“Can you check if https://store.example.com/products/sneaker-air-max still shows 'sold out' anywhere on the page? I want to know if it's back in stock.”
Price wording verification on listing
“Look at https://listings.example.com/item/4821 and tell me whether the phrase '$299' appears on the page — I need to confirm the price hasn't changed.”
Compliance clause check on policy page
“Fetch https://example.com/privacy-policy and check whether it contains the phrase 'data retention period' — I need to confirm this required wording is still there.”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/site/containsWhen to prefer
Use this endpoint when you need a quick, low-cost single-call check to determine whether a specific phrase appears anywhere on a publicly accessible web page — ideal for stock/price monitoring, compliance spot-checks, or content verification. Prefer this over full page scrapers when you only need presence/absence of a phrase rather than structured data extraction.
Side effects
- URL is unreachable or returns a non-200 HTTP status — endpoint may return an error or empty result
- Page uses heavy JavaScript rendering and text is not in raw HTML — phrase may not be found even if visible in browser
- Phrase is present only in images or PDFs embedded on the page — not detected since only readable text is searched
- Malformed or missing URL parameter — returns a validation error
- Rate limiting or bot-blocking on the target site — fetch may fail
