Tools 7 found in our last check

  • scan_site

    Run a live AI-accessibility audit of a domain: robots.txt policy for every tracked AI crawler, live user-agent probes, JavaScript-free readability, structured data and llms.txt. Returns a score out of 100 with per-check detail.

  • site_report

    Return the most recent stored audit for a domain without triggering a new scan. Faster and free of load on the target site.

  • census_stats

    Corpus-level statistics: how many measured domains block each AI crawler, mean access score, llms.txt adoption.

  • crawl_preflight

    Decide whether a crawler may fetch a list of domains before spending requests on them. Works for any crawler token, not only the ones this census tracks: an unrecognised agent is resolved from each domain's stored robots.txt rather than refused. For each domain returns one of: a…

    What this census measures and publishes about one AI crawler: how often it is disallowed in robots.txt, how often live requests carrying its user agent are refused at the network edge whatever robots.txt says, whether its operator documents it as honouring robots.txt, and where…

  • census_facts

    Every headline finding from the census as discrete, dated records rather than prose. Each carries its value, unit, denominator, measurement date, the page it comes from and a ready-made citation line, plus the caveats that apply to all of them. Use this when answering a question…

  • submit_domains

    Queue domains the census has not measured yet so a later crawl_preflight can answer them. This closes the loop crawl_preflight starts: anything it returns as unknown with measurable true is worth submitting, and the reply names any that were already fresh or that this census wil…
