## 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 research-json-structure-inspector-0b844ee6 -d '<json body>'
```

Example prompt: Can you inspect this JSON string and tell me its root type, what top-level keys it has, and how many items it contains: '{"name":"Ada","active":true,"items":[1,2]}'?

## When to prefer this

Use this endpoint when you need a fast, cheap structural summary of a JSON string — root type, keys, and item count — without needing full schema validation or deep traversal. Ideal for research workflows where you want to quickly understand unfamiliar JSON payloads before further processing.

## Known failure modes

- Invalid JSON string causes a parse error response
- Empty or missing 'json' field returns a validation error
- Deeply nested structures only report top-level keys, not nested ones
- Malformed Unicode or escape sequences may cause parsing failure

## How this service works

Research JSON structure inspector: Parse JSON and report its root type, keys, and item count. Tailored for research workflows.

## Output

Returns the root type of the JSON (e.g. object, array, string, number), a list of top-level keys if the root is an object, and the count of items (keys for objects, elements for arrays).

## Request schema (JSON Schema)

```json
{
 "type": "object",
 "properties": {
  "json": {
   "type": "string",
   "default": "{\"name\":\"Ada\",\"active\":true,\"items\":[1,2]}"
  }
 }
}
```
