Audio

Retrieve Voice Changer

Poll a queued voice conversion. While the conversion is still running this returns status: "PROCESSING" as JSON; once it finishes it returns the converted audio bytes.

A completed response carries the audio alongside x-venice-audio-format, x-venice-audio-duration, x-venice-inference-time, x-venice-model-id and x-venice-model-name.

Only the account that queued a conversion can poll it. Any other queue_id — unknown, belonging to someone else, malformed, or older than the retrieve window — is reported the same way, as an invalid request id.

If the provider fails the conversion, the charge is refunded automatically and the response reports whether that refund succeeded in credits_refunded. The outcome is recorded, so polling again replays the same result rather than refunding twice.

When credits_refunded is false and the conversion was charged, the error message says what to do about it: a refund that was attempted and did not go through asks you to contact support and is retried by polling again, and a request id the provider no longer recognises is reported as too weak a verdict to reverse a charge on. A conversion that was never charged, or one already delivered, reports false with nothing further.

Authentication: This endpoint accepts either a Bearer API key or a SIGN-IN-WITH-X header for x402 wallet-based authentication. The legacy X-Sign-In-With-X header is also accepted during migration. When using x402, a 402 Payment Required response indicates insufficient balance and includes top-up instructions.

Use the queue_id returned by /audio/voice-changer/queue to check conversion status. While the job is running this returns JSON with status: "PROCESSING"; when it finishes it returns audio/mpeg. Set delete_media_on_completion to true to clean up stored media in the same call, or call /audio/voice-changer/complete after you download the file. Voice-changer models are not accepted on /audio/retrieve.

Authorizations

Authorization

string

header

required

Bearer authentication header of the form Bearer <token>, where <token> is your auth token.

Body

application/json

model

string

required

The model that is running the conversion. Only voice-changer models are accepted on the /api/v1/audio/voice-changer endpoints.

Example:

"elevenlabs-voice-changer"

queue_id

string

required

Pass this to /audio/voice-changer/retrieve to poll for the converted audio, and to /audio/voice-changer/complete when finished.

Example:

"0190f2c4-9c1e-7a3b-8f42-2c9d5e7a1b34"

delete_media_on_completion

boolean

default:false

Release the provider-held media as soon as this call returns the audio, so a separate /audio/voice-changer/complete call is unnecessary. The audio cannot be retrieved again afterwards.

Example:

false

Response

Conversion still processing, or the completed audio

status

enum<string>

required

The conversion is still running. Poll again.

Available options:

PROCESSING

Example:

"PROCESSING"

average_execution_time

number

required

Recent average end-to-end time for this model in milliseconds. Use it to pace polling.

Example:

10000

execution_duration

number

required

Milliseconds elapsed since the conversion was queued.

Example:

4200
