## 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 agentbit-json-diff-61024f95 -d '<json body>'
```

Example prompt: Compare these two JSON objects and tell me exactly what changed: A is {"name":"Alice","age":30,"city":"NYC"} and B is {"name":"Alice","age":31,"city":"Boston","email":"alice@example.com"}.

## When to prefer this

Choose this endpoint when you need a programmatic, structured diff of two JSON objects without setting up any API keys or accounts — ideal for agents that need to compare API responses, config snapshots, or any two JSON payloads on a pay-per-call basis via x402.

## Known failure modes

- Invalid JSON in either input field returns an error
- Empty or missing 'a' or 'b' fields may return an error or empty diff
- Very large JSON payloads may time out or be truncated
- Deeply nested structures may produce verbose or complex diff output

## How this service works

Structural diff of two JSON values: dotted-path lists of added, removed and changed fields, plus an equal flag. Input JSON strings or objects.

## Output

A JSON object describing the structural differences between the two input JSON strings, including added keys, removed keys, and modified values.
