Technical details
Endpoint
GEThttps://api.glianalabs.com/x402/gpt-4o-transcribe?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need keyless, pay-per-call audio transcription using GPT-4o's Whisper model without managing an OpenAI API key or subscription. Ideal for AI agents operating autonomously with a crypto wallet (USDC on Base, Tempo, or Solana) that need to transcribe audio on demand. Prefer over direct OpenAI API when you want x402 micropayment settlement and no prior signup.
Side effects
- Unsupported audio format — only flac, mp3, mp4, mpeg, mpga, m4a, ogg, wav, webm are accepted
- File too large — files must be ≤40MB; use /v1/media upload endpoint first for large files
- Invalid data URI or inaccessible HTTPS URL — file must be publicly reachable
- Payment failure — insufficient USDC balance on Tempo, Base, or Solana wallet
- Language mismatch — prompt doesn't match audio language, reducing accuracy
- Audio quality too low — heavy noise or distortion may yield poor transcription
