## 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 catalog-engine-mcp-1ee2ba1a -d '<json body>'
```

Example prompt: Can you search the catalog engine for all products matching 'wireless headphones' and return me the structured listing results?

## When to prefer this

Use this endpoint when you need to process, search, or transform product/item catalog data through an agentic MCP interface. Prefer it for catalog-specific workloads where structured product retrieval or transformation is needed and payment via x402/USDC is acceptable.

## Known failure modes

- Empty or malformed data string returns an error or empty result
- Payment failure (402) if USDC balance is insufficient
- Timeout if catalog dataset is very large
- Unrecognized catalog format may return null or partial results
