## 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-commerce-json-type-inspector-cff1e760 -d '<json body>'
```

Example prompt: Can you inspect this JSON string and tell me what type it is at the root level and how large it is: '{"name":"Alice","age":30}'?

## When to prefer this

Use this endpoint when you need a quick, cheap, pay-per-call inspection of a JSON string to determine its root type and structure without setting up an account or subscription. Ideal for AI agents that occasionally need to classify JSON blobs as part of a larger pipeline, especially when no local JSON parsing is available or desired.

## Known failure modes

- Invalid or malformed JSON text returns an error or unexpected result
- Empty string input may result in a parsing error
- Very large JSON payloads may be truncated or rejected
- Payment failure via x402 protocol prevents request from being processed

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output

Returns a JSON object containing the size (number of top-level keys or items), the schema identifier (e.g. 'delx/json-type/v1'), and the root type of the parsed JSON (e.g. 'dict', 'list', 'string', 'number').
