## 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 creator-desk-json-keys-extractor-c802a3bc -d '<json body>'
```

Example prompt: Can you extract all the top-level keys from this JSON object for me: {"name": "Alice", "age": 30, "email": "alice@example.com"}?

## When to prefer this

Choose this endpoint when you need a quick, paid-per-use utility to programmatically extract the top-level keys from an arbitrary JSON value without writing custom parsing code. Useful in agentic pipelines where JSON structure is unknown at design time and needs to be inspected dynamically. Prefer this over custom code execution when operating in environments with x402 micropayment support and no local code execution capability.

## Known failure modes

- Input value is not a JSON object (e.g. array or primitive) — may return empty result or error
- Malformed JSON input — endpoint may return a parsing error
- Missing required 'value' field in request body — likely returns an error response
- Network timeout or service unavailability on Render hosting

## How this service works

Machine-callable x402-paid utilities for autonomous agents.

## Output

Returns a JSON object containing an 'operation' field set to 'json_keys' and a 'result' field with the list of extracted top-level key names from the input value.
