## 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 manylives-ai-audio-transcription-a34cdb37 -d '<json body>'
```

Example prompt: Can you transcribe this audio file for me? It's at https://upload.wikimedia.org/wikipedia/commons/5/52/En-us-hello.ogg — I think it's in English.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
