Agent-ready check

Is a domain agent-ready? Check its catalog against the ARD v0.91 specification. The checks run on our servers, the same way our crawler reads your catalog. Passing? Add your domain and we'll crawl it.

Private ARD · early access Your team uses AI tools too. Private ARD keeps a private list of the ones you approve, and each team's agents find only theirs. Join the early-access waitlist →

Publisher scoreboard

Publishers in the index · last check 16d ago

Discovery file speed

How long the publishers with the most records in our index take to serve their own catalog file (/.well-known/ard.json, or the older ai-catalog.json). p50 is the typical time, p95 the slow end.

Measured from our crawler on GitHub Actions, last sample Oct 16, 2026. One request per publisher per crawl (about four crawls a day), the same request the crawl makes anyway, over the last 7 days. The request reuses the connection the crawler opened for the site's robots.txt. So the times leave out the DNS lookup and connection setup. They include them when the site redirects to another host, or when that connection closed first. It closes, for example, when the site's robots.txt asks us to wait 4 seconds or more between requests. Network location changes these numbers: an agent in another region or network will see different times. Publishers can check their own domain with the checker above.

About Lighthouse and other scanners

Lighthouse 13.5 looks for the old file name, ai-catalog.json, unless robots.txt or a rel="ai-catalog" link points it to your file. So a site with its file only at /.well-known/ard.json can see "Not applicable" there. That does not mean your file is wrong, and an Agentmap line in robots.txt fixes it. For bot rules, markdown and payments, also run Cloudflare's scan at isitagentready.com.

Questions

Do you store the domain I check?

No. We keep no list of checked domains, and we count checks by result only. A result stays in a private cache for 10 minutes so a repeat check is fast, and then it is gone. If your domain is already in our index, the ARD file check updates its row in the publisher table on this page.

Why does Lighthouse say Not applicable?

Lighthouse 13.5 looks for your ARD file in three places: an Agentmap line in robots.txt, a rel="ai-catalog" link, or /.well-known/ai-catalog.json, the old file name. If your file is only at /.well-known/ard.json, Lighthouse does not find it and says Not applicable. Your file is fine. Add an Agentmap line to robots.txt and Lighthouse finds it too.

How do I get listed?

Add your domain on our publish page. Our crawler reads your ARD file and lists the tools in it. Most listed tools today are built for developers. Add your domain →

Do you check bot rules or payments?

No. We check llms.txt, your ARD file and whether we list you. For bot rules, markdown and payments, run Cloudflare's scan at isitagentready.com.
