## 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-dict-keys-96e54503 -d '<json body>'
```

Example prompt: What are all the keys in this JSON object — {"name": "Alice", "age": 30, "role": "admin"} — and how many are there?

## When to prefer this

Use this endpoint when an AI agent needs to quickly introspect the structure of a JSON object it already holds in memory — particularly when the object's schema is unknown or dynamic. It is ideal for lightweight, stateless key enumeration without shipping a code execution environment. Prefer this over writing custom code when operating in a no-code pipeline or when you want a reproducible, paid-per-call audit trail for introspection steps.

## Known failure modes

- Missing or non-object input — returns error if 'object' field is absent or not a JSON object
- Empty object — returns keys array as empty with count 0
- Deeply nested objects — only top-level keys are returned, not recursive keys
- Malformed JSON in request body — returns parse error

## How this service works

List object keys. Call when you introspect agent-held JSON objects. Returns keys and count 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 the list of top-level key names found in the submitted JSON object, along with a count of how many keys were found. No data is retained server-side; results are purely derived from the submitted object.
