Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-schema-type-extractor-d1ea4c03 -d '<json body>'
```

Example prompt: Can you extract the JSON Schema type for this value: {"name": "Alice", "age": 30}? I need to know what schema type it corresponds to.

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call utility to programmatically determine the JSON Schema type of an arbitrary value without setting up local type-detection logic. Useful in agentic pipelines where data origin is unknown and schema-aware routing or validation is required.

## Known failure modes

- Missing or malformed 'value' field in the request body returns an error
- Payment not included or insufficient USDC causes HTTP 402 rejection
- Unrecognized value format may return an ambiguous or generic type result
- Network timeout on the Render.com host if the service is cold-starting

## How this service works

Machine-callable x402-paid utilities for autonomous agents.

## Output

Returns a JSON object containing a 'result' field with the extracted schema type classification and an 'operation' field confirming 'schema_type_extract', indicating the detected type (e.g. string, number, object, array, boolean, null) of the provided value.

## Request schema (JSON Schema)
