How this service works
Pay-per-call tools for people building AI agents: live web search and page contents, point-in-time crypto market data and news for backtests (no lookahead), verifiable track records of 1,000 crypto strategies locked on the Base network, company profiles, quick AI and batch prices. Ask us to turn a public website into a JSON endpoint. Pay per call, no account, free trial.
Output
Returns a JSON object with the full transcribed text string, the detected (or specified) language code, an array of timestamped segments each containing start time, end time, and the spoken text for that segment, and the total audio duration in seconds.
Example use cases
Podcast episode transcription
“I have a podcast clip hosted at https://mypodcast.com/episodes/clip42.mp3 that's in English — can you transcribe it and give me the full text with timestamps?”
Multilingual audio note to text
“I recorded a voice note in French and uploaded it to https://storage.myapp.com/notes/note-fr.ogg — please transcribe it, making sure to detect the language correctly.”
Base64 audio snippet transcription
“Here's a short audio clip encoded in base64 — can you transcribe it to text for me? It should be in English.”
Technical details
Endpoint
POSThttps://api.manylives.me/paid/audio/transcribe?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a simple, pay-per-call (no account required) audio-to-text transcription with timestamped segments and language detection, especially when your agent already operates on the Base network and can pay $0.01 USDC per call via x402. It is ideal for lightweight, one-off transcription tasks without committing to a subscription or managing API keys.
Side effects
- Audio URL is not publicly accessible or returns a non-200 HTTP status — transcription will fail
- Base64 payload exceeds ~700 KB limit — use URL parameter instead
- Unsupported audio format — endpoint may return an error or empty transcript
- Invalid or malformed language code — may fall back to auto-detection or return an error
- Payment failure or insufficient USDC balance on Base network — 402 response returned
- Very noisy or silent audio — transcript may be empty or inaccurate
