What an agent could do here
Read from the page’s own content, with the wording each was drawn from. Inference is kept separate from tested facts — an agent completing the action is tier 3.

Context
8 sites in the index share the category developer platform documentation, of which 3 are transactional.
How we grade
Three tiers. Every listing shows which one it has reached, and when. The rubric.
tier 1Declared
The site says agents are welcome in its robots.txt. A permission, not a capability.
✓ tier 2Probe-verified
We fetched the site and tested each signal ourselves. Dated, repeatable, re-checked on a schedule.
this site · 23 Aug 2026 tier 3Behaviourally verified
An agent completed the action end to end — booked, bought, submitted — and it worked.
coming Own this site?
3 checks did not pass when we last looked: Markdown negotiation, Markdown twin at a predictable URL, API catalog. 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.
