## 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-audio-dub-f14072e3 -d '<json body>'
```

Example prompt: Can you dub this English audio file into Spanish for me? The file is at https://upload.wikimedia.org/wikipedia/commons/5/52/En-us-hello.ogg — I need the dubbed WAV audio plus the SRT subtitles.

## When to prefer this

Choose this endpoint when you need to both translate AND produce a synthesized audio dub of an existing audio file in one step, rather than just transcription or text translation alone. It is especially well-suited for agents building multilingual podcast platforms, e-learning tools, or content localization pipelines that need subtitle files (SRT/VTT) alongside a playable dubbed audio file, all in a single pay-per-call request with no account required.

## Known failure modes

- Invalid or unreachable audio URL returns an error
- Unsupported target language code returns a validation error
- Audio file too large when using base64 input may be rejected
- Missing both url and audio_base64 fields causes a bad request error
- Network timeout if the source audio URL is slow to respond
- Download URL for the voiceover expires after the indicated expires_at timestamp

## 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

A JSON object containing: the dubbed audio as a WAV file accessible via a temporary download URL (with size in bytes, duration in seconds, and expiry timestamp), SRT and VTT formatted subtitle strings, an array of transcript lines each with start/end timestamps and both source and translated text, and the detected or specified source and target language codes. A note on voice indicates a stock voice is used rather than the original speaker's voice.
