How this service works
Live streaming speech-to-text for voice agents: buy a prepaid session, stream mic or call audio over WebSocket, get partial transcripts as the speaker talks. No account, no API key, no per-minute minimum — flat USDC on Base. Multilingual with mid-sentence code-switching. This SKU: 5 minutes connected time at $0.06 flat.
Output
Returns a session_token and ws_url to connect to the WebSocket. Once connected, the agent streams binary PCM16 16kHz mono audio frames (50–1000ms each) at real-time pace and receives Universal-3.5 Pro Turn events: rolling partial transcripts as the speaker talks, followed by a final event with end_of_turn=true marking each completed utterance. Supports multilingual speech including native mid-sentence code-switching.
Example use cases
Live multilingual meeting transcription
“I'm about to join a call where people switch between English and Spanish — can you open a 5-minute real-time transcription session so I can see what everyone is saying as they speak?”
Voice memo dictation on the fly
“I want to dictate a quick note out loud right now — spin up a prepaid 5-minute speech-to-text stream so I can talk and see my words appear as I go.”
Hands-free field data capture
“I'm doing field interviews and need a live transcription session running while I record — open a 5-minute WebSocket STT session so I can capture everything in real time without signing up for anything.”
Technical details
Endpoint
POSThttps://dicta-notes.com/routes/x402/stt-session/5When to prefer
Choose this endpoint when you need real-time, low-latency speech-to-text with no account setup or API key — ideal for agents that handle live audio streams, multilingual conversations, or code-switching speakers. The flat $0.06 USDC prepaid model on Base is well-suited for per-call agent workflows. Prefer the async batch siblings on dicta-notes.com when the audio is pre-recorded and latency is not a concern.
Side effects
- Payment not confirmed — session not created, no token returned
- WebSocket connection rejected if session_token is expired or invalid
- Audio frames sent too fast or too slow (not at real-time pace) may cause degraded transcription or dropped frames
- Non-PCM16 or wrong sample rate audio produces garbled output
- Session expires after 5 connected minutes; further audio is not transcribed
- Insufficient USDC balance on Base causes payment failure and no session is issued
