Tariffmonkee · Paid Content
tariffmonkee.com
Fetch a URL with a real rendered browser (JavaScript executed) and return clean Markdown. Results are cached for 24 hours per URL, so repeat calls for the same page are fast and don't re-render.
Tariffmonkee · Paid Search
tariffmonkee.com
query -> structured search results (title, url, snippet), up to 10 per call. Backed by three providers with automatic failover (DataForSEO primary, Tavily and Serper as fallback) so a single provider outage doesn't take the endpoint down.

Tariffmonkee · Paid Extract URL
tariffmonkee.com
Fetch a URL with a real rendered browser and extract structured data from it in one call, using AI (tries multiple models in sequence for reliability). Use this when you don't already have the page content; use the cheaper /extract if you do. Results are cached for 24 hours per URL+schema combination.
