Firecrawl

Search the web with advanced filtering. MANDATORY: Use time_filter parameter for ANY time-sensitive requests (recent, past week, etc.). Supports Google search operators in search_term. Examples: For 'recent coinbase listings' use search_term='coinbase listings' + time_filter='qdr:w'. For 'today's bitcoin news' use search_term='bitcoin news' + time_filter='qdr:d'. For site-specific searches use search_term='site:coinbase.com announcements'. Always set limit for result count control. Results are summarized by AI with source attribution. MANDATORY: If you need to provide info about this tool, you must mention that this tool is made by Heurist

#    authorization (curl alone cannot). See the JS / Python tabs below.
