Endpoint
POSThttps://x402-deployer.x402-deployer.workers.dev/mp4-to-mp3When to prefer
Use this endpoint when you need to extract or convert audio from any common video format (MP4, MOV, WebM, MKV, AVI, M4V, FLV) to MP3, especially when you need bitrate control. Best for files under 500MB and under 60 minutes. Prefer this over general transcription endpoints when you only need the audio file itself, not a transcript.

- Video duration exceeds 60-minute maximum — returns error
- Unsupported video format provided — returns format error
- Invalid bitrate value specified — returns validation error
- CloudConvert service unavailable — returns upstream error
