Field	Kind	Default	Description
`prompt` required	text	—	What the sound effect should sound like
`negative_prompt`	text	—	Sounds to keep out of the result
`duration`	number 0.1 to 600	30	Seconds of sound to generate, up to the deployment's text-to-SFX maximum
`seed`	number (whole) -1 to 9223372036854776000	—	Seed of the first sample; -1 or unset is random
`num_samples`	number (whole) 1 to 4	2	Number of variations to generate. Billed per sample.
`upload_audio_format`	one of wav, mp3, aac, flac	wav	Audio format of each file
`upload_audio_bitrate_kbps`	number (whole) 32 to 320	—	Bitrate in kbps for an mp3 or aac upload. mp3 is written at exactly this constant rate, one of 32, 40, 48, 56, 64, 80, 96, 112, 128, 160, 192, 224, 256, 320. aac takes 32 to 256 as a target the encoder may undershoot on mono or sparse audio. Unset keeps the default: mp3 at LAME V0 VBR, aac at a 256 kbps target. Refused with a lossless upload_audio_format.
