11 of 16 measurable points under formula 9.2, measured on 2026-08-12. 15 checks exist; each is one HTTP request with a published rule, so every sentence below can be rerun and argued with. 1 of them could not be measured from where we ask, and those are left out of the denominator rather than counted as failures.
A · Discovery

D · Provisioning

- UNMEASUREDFree tier or no-card trial stated in textUnmeasurable: https://stripe.com/pricing is larger than we read, so anything we did not find in it is a fact about our cap and not about your tiersNothing for you to do. A smaller pricing page, or one that states its tiers early, makes this measurable.
E · Integration
- PASSTyped SDK on the registrystripe@22.5.0 ships types, matched from the registry by who publishes it rather than by a link on your site
- PASSMachine-readable API descriptionDocs serve markdown to machines, at https://docs.stripe.com
Tell me when this changes
The failures here are the kind nobody notices. An edge rule that starts refusing agents changes nothing a person sees in a browser, so the first sign is usually an integration that quietly stopped working. We rescan weekly and write only when a verdict moves.
This page is the newest scan we hold for stripe.com and changes when we rescan. It is not a judgement of the product: we measure whether an unattended run can get through, not whether the thing is any good. The whole corpus is published as JSON and CSV.
