Status values

Status	Keterangan
`queued`	Tugas sedang diantrikan.
`processing`	Sedang diproses.
`succeeded`	Berhasil.
`failed`	Gagal — lihat error detail, tidak ditagih.

Output bertipe audio/mpeg, dilayani dari CDN kami dan berlaku 7 hari — salin ke penyimpananmu sendiri untuk jangka panjang.

Best practices

Bila generation gagal, task berstatus failed dengan error.code ternormalisasi (mis. moderation_blocked, upstream_error) dan price.final = 0 — saldo dikembalikan otomatis. Daftar lengkap kode error ada di Error handling. Selalu kirim Idempotency-Key unik per tugas agar retry aman.

Coba tanpa kode: jalankan model ini langsung dari Playground atau lihat di API Market.
