## 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 docparse-json-utility-27e9877b -d '<json body>'
```

Example prompt: Can you validate this JSON for me and tell me if there are any syntax errors — if it's valid, pretty-print it with 4 spaces of indentation: {"name":"Alice","age":30}

## When to prefer this

Choose this endpoint when you need a pay-per-call, no-account JSON utility — especially useful for AI agents that occasionally need to validate or reformat JSON as part of a larger workflow without setting up an API key. Ideal for lightweight, one-off validation or formatting tasks where the $0.001 USDC micropayment model fits better than integrating a heavier library or service. Prefer alternatives if you need bulk processing of many JSON documents simultaneously.

## Known failure modes

- Malformed input that is not JSON returns valid:false with line/column error location
- Empty input string may return a validation error
- Payment failure (x402) if USDC micropayment cannot be processed — no charge on failure
- Indent value out of range (0–8) may be rejected
- Mode enum value not matching validate/pretty/minify returns an error

## How this service works

Pay-per-call tools for AI agents: any document to clean Markdown (PDF, Word, Excel, PowerPoint, web pages); US company fundamentals, SEC filings and insider trades; Treasury yields; FRED macro data; official FX rates (ECB, Bank of Russia); hash, base64, JWT, UUID and JSON utilities. x402 USDC micropayments, no account or API key. Charged only on success.

## Output

Returns a JSON object with a 'valid' boolean field. On success (valid JSON), returns the processed text (pretty-printed or minified if requested). On failure, returns 'valid: false' plus an 'error' string describing the syntax problem along with 'line' and 'column' integers pinpointing where the error occurred.
