## 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 alexandria-x402-parts-search-api-b5e27d62
```

Example prompt: My 1993 Geo Metro XFi has been making wind noise at highway speed — can you search Alexandria for parts related to that symptom so I know what might need replacing?

## When to prefer this

Choose this endpoint when an AI agent needs to assist a user in identifying or finding automotive parts for car repair, especially when the query involves symptom-based diagnosis (e.g. 'wind noise at speed') or a specific vehicle badge/model/year. It is well-suited for agentic workflows that accept per-call micropayments via x402/USDC rather than subscription billing.

## Known failure modes

- No results found for highly specific or obscure part queries
- Payment failure via x402 protocol returns 402 status before data is delivered
- Vague or ambiguous keywords may return loosely relevant results
- Unsupported vehicle models or years may yield no vehicle-specific matches
- Rate limiting or server unavailability on the hosted render instance
