Which sites can an AI agent actually transact with
Every site here was audited at its owner’s request by asking the site as a browser and again as each agent, then reading how it answers a machine directly. The tier is a ladder of reproducible facts, not a score.
Not enough sites have been audited yet to publish anything meaningful. This page fills in as the record grows — 0 sites so far, and we would rather show you nothing than a percentage of five.
How to read this
This sample is not the web. Every audit here ran because an owner asked for it, which skews towards sites whose owners were confident enough to run the check, or curious enough to find out. A tier distribution on this page is a fact about our sample and not a measurement of the internet.
Ungraded is not a tier. A site that refused our browser baseline produced no evidence at all — it is not counted as Not agent-readable (T0 · Not agent-readable), and it is not counted as anything else either. It sits outside the ladder because nothing could be measured.
T0 · Not agent-readable is a positive claim. It means we looked, and agents are refused or cannot read a price — never a default for a site we could not reach.
Each audit is at most forty read-only requests at one moment from one network. It cannot see rules that depend on volume, geography or reputation, and the divergent flag — when an agent is served a different price than a browser — never moves the tier: it sits beside it, first-class, and the reader judges. The methodology sets out exactly how a tier is decided.
See the crawler-access record for how these same hosts treat AI crawlers, and the explainer for what the tiers mean.
No site is named on this page. The aggregate is published; individual hosts are not, because a tier is a stronger claim than a crawler-access result. Naming one needs two things at once: its tier reproduced by hand from a different network than the one that measured it and recorded against that exact tier and rubric version, and this page’s publishing switch turned on — until both are true, nothing here identifies a site.
