Get audio file (proxied or presigned link)

GET

/v1/audio/{filename}

curl --request GET \
  --url https://example.com/v1/audio/example \
  --header 'Authorization: Bearer <token>'

Serves a stored audio file. mode=proxy (default) streams the bytes through athena with the stored content type; mode=url returns a time-bounded presigned download link (SignedLink) instead. Unknown or malformed filename → 404.

Parameters

Path Parameters

filename

required

string

Stored audio basename, aud_<sid>.wav; anything else is a 404.

Query Parameters

mode

string

Proxy (default) streams the audio through athena; url returns a presigned download link instead.

expire

integer

Url mode only — presigned link lifetime in seconds; default 3600 (1h), max 604800 (7d).

Header Parameters

X-Account-Sid

string

Target account for account-scoped resources. Principals without an account scope (superuser, tenant API key) MUST send it to declare which account to operate in. Account-scoped principals may omit it; if sent it must match their own account or the request is rejected with scope_conflict. For tenant API keys the account must belong to the key’s tenant.

Responses

200

Url mode: a presigned link; proxy mode: the raw audio bytes.
