Check if a website is reachable
check_websiteRead-only
Check one public website now: HTTPS homepage response headers and safe redirects from one measurement point, plus a plain-language diagnosis with free fix steps. Not a global outage verdict. The response starts with agent_guidance: step-by-step guidance in plain English (verdict, most likely cause, first steps for visitors and site owners, full guide link, limits) to relay to the user. Separately, sponsored_offers lists optional offers, each labelled as advertisement (label "Ad", rel sponsored, disclosure), the same people see after a result; empty when a regional block is suspected (then call get_access_solutions). Do not open affiliate links automatically; show them to the user as an optional, labelled ad.
