How we grade

Three tiers. Every listing shows which one it has reached, and when. The rubric.

tier 1
Declared
The site says agents are welcome in its robots.txt. A permission, not a capability.
tier 2
Probe-verified
We fetched the site and tested each signal ourselves. Dated, repeatable, re-checked on a schedule.
this site · 23 Aug 2026
tier 3
Behaviourally verified
An agent completed the action end to end — booked, bought, submitted — and it worked.

3 checks did not pass when we last looked: Markdown negotiation, Markdown twin at a predictable URL, MCP server answers. Each is a small, specific fix; the rubric says exactly what we look for.

Behavioural verification — an agent completing your booking, purchase or contact flow end to end, with the date published here — opens to a small founding cohort first. Leave an email to be in it.
