What
API error telemetry now records whether a custom base URL, an auth token or an API key helper is in use, plus a coarse classification of the API key prefix, so failures can be attributed to a configuration shape rather than an individual credential.
Details
Server responses are mapped onto a fixed set of error type and code values, with anything unlisted reported as "other".
