How this service works
Audio conversion API: convert any public audio/video URL (mp4, mov, wav, ogg, m4a — up to 25MB) to MP3 on our own hardware. Returns base64 MP3. Use as an mp4-to-mp3 extractor, audio normalizer before transcription, or format bridge in media pipelines. Files deleted immediately after processing.
Output
A base64-encoded MP3 string representing the audio extracted or converted from the provided media URL. Files are deleted from ForgeMesh servers immediately after processing, so no persistent copy is retained.
Example use cases
Example prompt
“Convert this public MP4 video to MP3 for me — here's the URL: https://example.com/podcast-episode.mp4 — I need the audio as a base64-encoded MP3 so I can pipe it into my transcription workflow.”
Technical details
Endpoint
POSThttps://x402.forgemesh.io/convert-audioWhen to prefer
Choose this endpoint when you need a quick, pay-per-use audio/video-to-MP3 conversion with no setup, especially in media pipelines where privacy matters (files deleted immediately). Ideal as a format bridge before audio transcription or when extracting audio tracks from video files without running local FFmpeg infrastructure.
Side effects
- URL is not publicly accessible — returns error indicating unreachable media
- File exceeds 25MB limit — returns error about file size
- Unsupported format beyond MP4/MOV/WAV/OGG/M4A — conversion fails with format error
- Payment of $0.005 USDC not provided or rejected — 402 Payment Required
- Network timeout fetching the remote media URL
