Generate Audio

Generate speech, music, or a sound effect from text (metered).

Pick mode first: text_to_speech (a voice saying your exact words — prompt IS the script), text_to_music, or text_to_sfx. The model card on GET /v1/media/models says which modes each model serves.

Synchronous: the render runs inside this call and there is no wait: false task lane. Speech returns in seconds. Music and sound effects can be asked for at up to 600 seconds of output and may take correspondingly longer; a render that outruns this call’s wait is asked to cancel and reported as a retryable 503. Repeat that call with the same idempotency_key: it adopts the existing provider job, so it returns the audio if the render finished anyway and reports it cancelled if it did not — and it can never pay for a second render. Only once it reports cancelled is a new request worth making — and that one needs a NEW idempotency_key as well as a shorter duration or fewer samples, since a changed payload under the old key is a 409 idempotency_conflict.

results carries one entry per delivered take (num_samples), applied reports the knobs that actually ran, and adjustments names every field that differed from the ask, with a reason — read them before describing the output to a user.

Moda-Version

enum<string>

default:2026-05-01

Calendar-dated API version pin. New integrations should pin 2026-05-01 to opt into the newest response shapes. For back-compat the server also accepts requests with no header and resolves them to the current default (today: 2026-04-12); that default advances on each sunset date. Any unsupported value returns 400 unsupported_version.

Available options:

2026-04-12,

2026-05-01

Example:

"2026-05-01"

Body

application/json

prompt

string

required

Sent to the selected model VERBATIM. For text_to_speech this IS the script — the words that get spoken, with no stage directions. For the other modes it describes the result: genre, instrumentation, mood, tempo, texture.

Minimum string length: 1

model

string

required

Concrete audio model id; see GET /v1/media/models.

mode

string

required

text_to_speech, text_to_music, or text_to_sfx. Stated rather than derived — every mode takes exactly text, so there is no input role to derive it from. The model card on GET /v1/media/models says which modes each model serves.

voice

string | null

Speech only. Normally a preset name from the mode's voices on GET /v1/media/models; on a mode whose card sets voice_is_free_form, voices is empty and this takes any provider voice name or cloned-voice id instead, checked for shape here and resolved by the provider. Omit for the mode's default.

duration_seconds

Music and sound effects only, and it SNAPS into the mode's envelope with the adjustment reported. Speech has no duration control — a value passed there is dropped and reported rather than rejected.

num_samples

integer | null

Distinct takes to render, where the mode has a sample axis (max_samples on GET /v1/media/models). EVERY sample is billed, and a mode with a billing floor bills each short take at the floor.

model_params

Model Params · object | null

idempotency_key

string | null

Keys the provider-job checkpoint: a retried call with the same key resumes the existing render instead of paying for a duplicate.

Maximum string length: 200
