The documentation that would carry them sits behind the Pearson Developers Network login (HTTP 401 on every path), and no live Pearson endpoint could be exercised anonymously to observe rate-limit response headers: api.pearson.com answers 403 "service that has been moved", and ws.pearsonvue.com rejects unauthenticated calls at the Azure API Management gateway.
