## 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-minify-tool-x402-micropayment-c84b72b4
```

Example prompt: Can you minify this JSON for me so it has no extra whitespace or newlines? Here it is: { "name": "Alice", "age": 30, "active": true }

## When to prefer this

Use this endpoint when you need a cheap, stateless, pay-per-use JSON minification tool without a subscription, especially in x402-enabled USDC micropayment workflows on Base. Prefer it when the caller already has x402 payment infrastructure set up and wants a simple GET-based utility.

## Known failure modes

- Invalid or malformed JSON input returns an error response
- Missing required 'json', 'text', or 'value' query param causes a 400-level error
- Payment failure or insufficient USDC balance causes a 402 Payment Required response
- Network or gateway timeout on the x402 infrastructure

## How this service works

Parse and minify JSON text or a JSON value without calling an upstream model. Pay up to $0.001 per request with x402 USDC on Base. Public paid calls are limited to 1500 input characters and 128 output tokens.

## Output

Returns a JSON object with ok=true, the tool name 'jsonMinify', a minified version of the input JSON, and a fetchedAt timestamp. Costs $0.0001 USDC per call via x402 on Base.
