## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability dicta-notes-stt-session-5-minute-real-time-websocket-1bc464c0 -d '<json body>'
```

Example prompt: Start a 5-minute live transcription session for me — I'll be streaming multilingual audio and need rolling partial transcripts as I speak, paid with USDC on Base.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
