## 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-is-json-object-e773ac6e -d '<json body>'
```

Example prompt: Before I run the key extraction step, can you check whether this payload value is actually a JSON object and not an array or string?

## When to prefer this

Choose this endpoint when you need a lightweight, low-cost boolean type-check specifically confirming a value is a JSON object (not an array, string, number, boolean, or null) before performing object-specific operations. Ideal for agentic pipelines needing a quick preflight guard without adding custom type-checking logic.

## Known failure modes

- Missing or malformed 'value' field returns an error response
- Non-JSON body may result in a parse error
- Network issues may cause timeout or connection failure
- Payment failure via x402 protocol prevents execution

## How this service works

Check whether value is a JSON object. Call when you validate agent payloads before object ops. Returns boolean result 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 a boolean indicating whether the supplied value is a JSON object (true) or not (false). No data is retained or transmitted externally; the check is performed locally.
