## 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 the-gem-smith-mcp-62607036 -d '<json body>'
```

Example prompt: Can you look up details about a 3-carat emerald — its typical properties, quality grades, and approximate value?

## When to prefer this

Choose this endpoint when you need gemstone-specific information such as identification, properties, grading, or valuation and want a dedicated gem-domain processing service rather than a general knowledge API.

## Known failure modes

- Empty or malformed data string returns an error or empty result
- Payment failure (402) if USDC balance is insufficient
- Unrecognized gem query may return no results or a generic fallback
- Service unavailable if the agentic endpoint is down
