## 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 neurodynamic-voice-cloning-result-retrieval-da7fe356 -d '<json body>'
```

Example prompt: My voice cloning job is ready — can you retrieve the finished WAV audio for job ID vc-8a3f21b9 from Neurodynamic?

## When to prefer this

Use this endpoint when you have already completed the enrolment, job submission, and polling workflow at the Neurodynamic /cloning endpoint, and the job status is confirmed as ready. This is the final retrieval step in the Neurodynamic voice cloning pipeline. Prefer this over general TTS or voice synthesis endpoints when you need to produce speech in a specific enrolled private voice (voice cloning) rather than a generic synthetic voice. Not suitable for initiating new cloning jobs or for transcription.

## Known failure modes

- Job not yet ready — job must be in a ready state before retrieval is attempted
- Invalid or unrecognized job_id — returns an error if the job ID does not match an existing queued/completed job
- Unapproved requester credential — returns authorization error if the caller's credential has not been approved
- Unauthorized private voice — returns error if the voice used in the job is not authorized for the requester
- Payment not completed or unrecoverable — x402 payment of 0.01 USDC on Base must succeed; consult /cloning for payment recovery
- Exceeded character limit — jobs submitted with more than 300 characters may fail or be rejected
- Binary response parsing errors — callers must handle raw WAV bytes correctly

## How this service works

Introductory pricing. Collect completed English cloned speech as WAV, 0.01 USDC on Base, up to 1,000 characters. Requires approved requester credential, authorized private voice and ready job. First read https://api.neurodynamic.tech/cloning for enrolment, queue and payment recovery. No payment is signed while queued. Accent and similarity vary.

## Output

A binary WAV audio file containing the completed English cloned speech output for the specified job. The audio reflects the enrolled private voice with variable accent and similarity. File is returned as audio/wav binary content.
