Findings
627 of the 638 Trusted Advisor checks, collected from APIs that cost nothing — plus 117 rules covering what none of them answer.
Trusted Advisor's full catalogue sits behind Business or Enterprise Support, priced per member account. For an organisation of any size that is a real line item. We classify all 638 checks by which ungated API reaches the same judgement, and collect 627 of them today.
634 checks have a route — a defensible statement about which free API could answer them. 627 have a collector calling that API right now. Those are different numbers and we publish both, because quoting the larger one would be the easy and dishonest choice.
627 collected, 7 declared unreproducible with a stated reason, 4 behind a separately priced AWS service. That is the whole catalogue, with no fourth bucket — so the day AWS adds a check, it surfaces as a gap rather than quietly diluting the claim.
Every finding carries a lifecycle. How long a condition has existed is often more useful than that it exists, and it is what turns a list into a trend. Because the rule engine is pure — snapshot in, findings out — a new rule replays over the snapshot archive and reports how long the condition has been true, rather than only seeing it from its deploy date forward.
