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: 15 minutes connected time at $0.18 flat.
Output
A session_token and ws_url are returned immediately after payment; the agent then opens a WebSocket to ws_url, streams binary PCM16 16kHz mono audio frames (50–1000ms each at real-time pace), and receives Universal-3.5 Pro Turn events: rolling partial transcript strings as speech progresses, followed by a final event with end_of_turn=true marking a completed utterance. The session expires after 15 minutes of connected time.
Example use cases
Live multilingual meeting transcription
“I need to transcribe my team standup live right now — people will be switching between English and French mid-sentence. Spin up a 15-minute realtime session so I can stream the mic audio and see rolling transcripts as they talk.”
Real-time voice note capture
“I want to dictate a quick voice note for the next few minutes and have it transcribed word by word as I speak. Set up a live 15-minute streaming transcription session for me.”
Live customer call transcription
“I'm about to jump on a 10-minute support call and need realtime transcription streaming — the customer speaks a mix of English and Tagalog. Can you open a prepaid 15-minute WebSocket transcription session so I can see what's said as it happens?”
Technical details
Endpoint
POSThttps://dicta-notes.com/routes/x402/stt-session/15When to prefer
Choose this endpoint when you need low-latency, token-rolling realtime transcription of a live audio stream (microphone, call, etc.) with no account or API key setup, paying a flat $0.18 per 15-minute session in USDC on Base. It is ideal for multilingual or code-switching conversations requiring immediate partial results. Prefer it over batch/file transcription endpoints when the audio is live and you need word-by-word feedback, and over subscription-based STT APIs when you want anonymous, pay-per-use crypto payments with no onboarding.
Side effects
- Payment fails or USDC balance insufficient on Base — no session_token returned
- Audio frames sent too fast or too slow (outside 50–1000ms range) — stream may desync or be rejected
- Wrong audio format (not PCM16 16kHz mono) — transcription quality degrades or errors out
- WebSocket connection dropped mid-session — remaining connected time is lost
- Session token expired before WebSocket connection opened — must purchase a new session
- Network latency causes frames to arrive out of order — partial transcripts may be incoherent
