Response headers

X-Request-IDstring

Unique identifier for this request, present on every response (2xx and non-2xx alike). If the caller sends an X-Request-ID request header the server echoes it back (sanitized and length-capped) so one logical request can be traced end-to-end; otherwise the server generates a fresh value. Log it on every response and quote it in support requests - it is the stable handle that ties your observation to Speechify’s server-side logs, and it matches the request_id field in the error envelope.
