## 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-name-utility-571ea44d -d '<json body>'
```

Example prompt: What is the JSON type name of this value: [1, 2, 3]? I need to know whether it's classified as an array, object, or something else.

## When to prefer this

Use this endpoint when you need a lightweight, pay-per-call utility to programmatically determine the JSON type name of an arbitrary value without setting up an account or subscription. Ideal for agent pipelines that need dynamic type inspection at low cost ($0.001 USDC per call) with verifiable delivery.

## Known failure modes

- Missing or malformed 'value' field in request body returns an error
- Payment not completed via x402 (USDC on Base or Solana) results in 402 Payment Required
- Invalid JSON submitted as input may cause parsing failure
- Network timeout or service unavailability returns a 5xx error

## How this service works
