- **Structured data found (LocalBusiness).** address, phone, opening hours
- **Menu or price list is an HTML page.** Agents can read the items and prices.
- **Booking through zenchef on your own domain.** There's no marketplace commission, and the customer stays yours.
- **Zenchef works with agents through its partners.** Zenchef's website terms (19 February 2024) forbid robots, scripts or automated systems that extract content and forbid crawling or scraping; agents book only through partner integrations a restaurant enables. Terms read on 2026-10-15: https://www.zenchef.com/terms-conditions. An assistant that isn't a partner may not be able to finish there. A direct path on your own domain works for all of them.
