7 of 13 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. 2 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

  • N/A
    Paths robots.txt points at answerrobots.txt names no concrete path, only patterns or nothing, so there is no claim to check

B · Agent entry

  • FAIL
    Agent entry pointNone of the 9 known agent entry paths returns a file rather than your page shell

C · Registration

  • UNMEASURED
    No CAPTCHA in the signup HTMLUnmeasurable: the signup form at https://app.crowdin.com/signup is not in the server HTML, so its gates are not eitherServer-render the form, or tell us the endpoint it posts to, and the gates become visible to us and to an agent.
  • FAIL
    Signup reachable without a browserhttps://app.crowdin.com/signup is reachable, but its form needs JavaScript

D · Provisioning

  • UNMEASURED
    Programmatic key provisioningUnmeasurable: only 1 documentation page could be read, which is too little to conclude anythingLink your API reference from your docs index or from llms.txt and this becomes measurable.
  • PASS

E · Integration

  • PASS

  • FAIL
    Machine-readable API descriptionNo OpenAPI spec at the 5 usual paths, none declared by https://docs.crowdin.com, and no markdown negotiationPoint at your spec from your docs page with rel="service-desc" and an agent finds it without guessing.

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 crowdin.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.
