## 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 delx-object-empty-ac70c697 -d '<json body>'
```

Example prompt: Can you check whether this JSON object is empty for me: {"user": {}}? I need to know if it has any keys before I continue.

## When to prefer this

Choose this endpoint when you need a lightweight, local, no-network check to gate agent workflows on whether a JSON object body is empty. It is ideal for pre-flight guards before expensive downstream API calls, and useful when you want a deterministic empty+size signal without writing inline logic.

## Known failure modes

- Non-object input (e.g. array or primitive) may return an error or unexpected result
- Malformed JSON body causes a 400-level error
- Missing 'object' field in request body returns an error
- Network timeout or service unavailability returns 5xx

## How this service works

Check whether an object is empty. Call when you gate agent workflows on empty JSON bodies. Returns empty flag and size for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.

## Output

Returns an empty boolean flag indicating whether the object has zero keys, along with the size (number of top-level keys) of the object.
