## 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 json-pretty-print-with-tab-indentation-773973ba -d '<json body>'
```

Example prompt: Can you reformat this JSON with tab indentation so it's readable? Here's the raw JSON: {"name":"Alice","age":30,"city":"Zurich"}

## When to prefer this

Choose this endpoint when you need tab-based (not space-based) JSON indentation specifically, and want a deterministic, offline transformation with no network calls or LLM involvement. Prefer the free sandbox endpoint POST /v1/sandbox/json-pretty-tab first; use this paid endpoint only if the sandbox is unavailable or you need guaranteed SLA. Avoid if you need space-indented output or any structural transformation beyond formatting.

## Known failure modes

- Invalid or malformed JSON input returns an error response
- Empty string input rejected due to minLength:1 constraint
- Input exceeding 100,000 characters rejected due to maxLength constraint
- Malformed request body or missing 'text' field returns a 400-level error
- Payment failure (wrong amount or missing x402 header) blocks execution

## How this service works

Call when an agent needs JSON rewritten with the pretty-tab transform. No network. Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/json-pretty-tab first.

## Output

A tab-indented, human-readable version of the submitted JSON string, with each nested level indented by one tab character. The response is a formatted JSON string with no changes to data values or structure.
