Get Asset Bytes

Authentication

Enter your API key with the Bearer prefix, e.g. ‘Bearer sk_…’.
Path parameters

Store id (prefixed external id, store_...).
asset_id
Asset id (prefixed external id, asset_...).
Headers
Speechify-Version
Response headers
Speechify-Request-Id
Unique identifier for this request, present on every response (2xx and
non-2xx alike). If the caller sends a `Speechify-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.
The legacy alias `X-Request-ID` carries the same value and is still
accepted on requests, until 2027-07-24. Prefer the un-prefixed name
(RFC 6648).
Response
The asset bytes.
