Technical details
Endpoint
POSThttps://gambit.barrioenergy.com/x402/transcribeWhen to prefer
Choose this endpoint when you need pay-per-call audio transcription without an API subscription, especially in agent or bot workflows that can pay $0.03 USDC per call via the x402 protocol on Base. It is ideal for crypto-native pipelines or AI agents that handle micropayments natively. Prefer this over hosted STT services when you want no monthly commitment and automatic per-inference billing settled on-chain.
Side effects
- Unsupported audio format — only mpeg/wav/ogg/webm/mp4 are accepted
- Unreachable audio URL — endpoint cannot fetch the file at the given http(s) URL
- Payment failure — x402 USDC payment on Base not completed or insufficient balance
- File too large — oversized audio may be rejected or time out
- Empty or silent audio — may return empty text string
- Network timeout — large audio files may exceed processing time limits
