## 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 lupariel-catalog-lookup-b32f8b85
```

Example prompt: Search the LupaRiel catalog for any production-status x402 services related to 'weather', limit results to 5.

## When to prefer this

Use this endpoint when you need to discover or verify production-ready services in the LupaRiel agentic API catalog, particularly those supporting the x402 micropayment rail. Prefer this over browsing /rieles.json directly when you want filtered, keyword-matched results rather than the full catalog dump. Ideal for agents that need to programmatically find and route to other x402-compatible services.

## Known failure modes

- No matches found for query — returns count 0 and empty matches array
- Invalid or missing query parameter — may return error or empty result
- Rate limiting or payment failure via x402 — call rejected before processing
- Overly broad query returning truncated results up to the specified limit
- Service temporarily unavailable — HTTP 5xx response
