## 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 geekvault-json-format-1a594cde -d '<json body>'
```

Example prompt: Can you format this minified JSON blob into something readable? Here it is: {"name":"Alice","age":30,"city":"New York"}

## When to prefer this

Choose this endpoint when you need a quick, keyless, no-signup way to format or prettify a JSON string, especially in automated agent pipelines that pay per-call via USDC on Base rather than managing API key subscriptions.

## Known failure modes

- Invalid JSON input returns a parse error
- Empty input body returns a 400 bad request
- Malformed or truncated JSON may fail to parse
- Extremely large JSON payloads may time out or be rejected
- Non-JSON text input will result in a formatting error

## How this service works

Network, docs, image, web, and dev utility tools paid per call via x402. No signup, no API keys, no subscriptions — just USDC on Base.

## Output

Returns the input JSON as a formatted, prettily-indented string with consistent whitespace and newlines, making nested structures easy to read and review.
