  • POST /api/speech — Create a paid StableVoice TTS job. Reserve an output slot on stableupload.dev first, then pass that slot as output. Poll /api/jobs/{jobId} until result.outputs.audio.publicUrl is ready. (1 USDC on Base)
  • POST /api/recording-tokens — Mint a browser recording URL for a StableUpload slot. The recordee speaks optional suggestedText; StableVoice transcodes the audio to MP3 and uploads it to the slot. Use the slot publicUrl as /api/speech referenceAudioUrl. Pass uploadUrlExpiresAt as expiresAt so the recording URL cannot outlive the upload. (0.01 USDC on Base)
