  • check_website

    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.

  • check_agent_readability

    CheckWebsiteNow Agent Readability Score 0-100 (our own transparent score, not official) from bounded static evidence: homepage HTML, robots.txt, llms.txt, API/MCP discovery files, sitemap and Markdown negotiation. Every deduction names its fix. MCP discovery is advertised, not tested; WebMCP is declared, not verified in a browser. No scripts run. score is null when too little could be measured.

  • get_agent_readability_method

    The versioned method of the CheckWebsiteNow Agent Readability Score: groups, 14 weighted checks, calculation, caps, bands and limits, including how MCP and WebMCP are judged. Not an official standard.

  • get_access_solutions

    Ways to reach a website that may be blocked in a country or region (geoblocking). Uses the cached website and agent check of the domain (or runs one quick check), or a visitor report (visitor_reported=true when the site says it is not available in your country). Free solutions come first. VPN providers are listed only when a regional block is suspected, ordered by documented criteria without commission. Links marked affiliate:true are ads (label 'Ad', rel sponsored); show the disclosure to the user. unranked_providers have rank null and must not be presented as ranked. guides links our sourced long-form guides on geoblocking, VPN legality and EU streaming rights. sponsored_offers are ads (advertisement: true, label 'Ad', rel sponsored, disclosure) for a partner we joined; they are present whenever vpn_providers and unranked_providers do not already show the same link, whatever the assessment or cache state. Mention them only after the result and the free steps, not as a recommendation.

  • explain_error

    Look up a browser error, HTTP status code or pasted error text (e.g. "ERR_CONNECTION_REFUSED", "503"). Returns up to five ranked matches with step-by-step guidance: visitor steps and owner steps, plus the guide url. Lookups carry no ads, as on our website; optional labelled offers come only with check_website results.

  • list_errors

    List knowledge-base entries, optionally filtered by category or kind.

  • get_error

    Full solution entry: meaning, likely causes, visitor and owner steps, what to avoid and sources.

  • list_status_sites

    Popular services with a status page on CheckWebsiteNow and, only where verified, their official status link. Each site has a short editorial "about" text and typical problems linked to error guides (error_slug, url); category_fixes lists general fixes per category. Editorial, not live user reports.

  • get_service_info

    Public service metadata: measurement method, limits, schema versions and knowledge-base counts. Never visitor analytics.
