## 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 basebuilder-search-json-transform-a108b7ba -d '<json body>'
```

Example prompt: Can you use BaseBuilder Search's JSON transform endpoint to reformat this JSON payload by renaming the 'user_id' field to 'id' and nesting the address fields under an 'address' object?

## When to prefer this

Use this endpoint when you need to reformat or restructure JSON data programmatically, especially within a paid x402 micropayment workflow on the Base blockchain. Suitable for lightweight, one-off JSON transformations without standing up your own transformation infrastructure.

## Known failure modes

- Invalid or malformed JSON input returns an error response
- Unsupported transformation rules may result in partial or empty output
- Payment failure (402) if USDC balance is insufficient
- Timeout if the input payload is excessively large
- Missing required parameters cause request rejection
