Technical details
Endpoint
POSThttps://cloudflare.payweave.services/transcribeWhen to prefer
Choose this endpoint when you need fast, edge-hosted speech-to-text with optional per-word timing and WebVTT subtitle output, especially if you want pay-per-call pricing via x402 USDC without managing API keys or subscriptions. Ideal for single audio files under 10 MB accessible via public URL.
Side effects
- Audio URL is not publicly accessible or returns a non-200 response — transcription fails
- Audio file exceeds 10 MB size limit — request rejected
- Unsupported audio format — model cannot decode the file
- Network timeout fetching the remote audio URL — transient failure
- Payment not received or insufficient — 402 response blocking the call
