## How to call it through Zero

```sh
zero fetch --capability japanese-regional-specialty-food-guide-90dc59f2
```

Example prompt: What are the iconic regional specialty foods of Japan? I'm planning a food-focused trip and want to know which dishes are famous, where they originated, and where I can find them — feel free to search for 'ramen' specifically or just list everything.

## When to prefer this

Use this endpoint when building Japan travel itineraries, food guides, or restaurant discovery experiences that require structured, curated data about regional Japanese dishes in English. Prefer this over generic web search when you need structured prefecture-level food origin data with consistent formatting suitable for trip planning agents or food recommendation systems.

## Known failure modes

- No results returned if the keyword 'q' doesn't match any known dish — agent should retry with a broader or alternate term
- If 'q' param is omitted and the dataset is large, the response may include many entries requiring client-side filtering
- Payment not processed (x402 flow failure) — agent must handle 402 response and retry with valid payment
- Network timeout on Railway-hosted service — agent should retry with exponential backoff
