Scanned: 2026-10-14 (Provisional: the action test and the assistant citation check still to come; the hatched part of the bar is not measured yet.)
De Proefzaak is mostly ready for agents.

## Direct links
- Book directly: https://deproefzaak.nl/amsterdam/#afspraak-toggle (on the business's own site)
- Menu: https://deproefzaak.nl/amsterdam/#menu
- Phone: +31 6 13941438

## What to fix first
- **Structured data is incomplete.** (+7 points) Missing: address, telephone, opening hours. Guide: https://directindex.org/guides/structured-data-restaurant
- **No llms.txt.** (no points, still worth doing) Optional today, cheap to add: a short text file describing the business for language models. Guide: https://directindex.org/guides/llms-txt-for-a-business

## Fix kit: What to paste

Structured data (JSON-LD). One block in the page's head, or in the builder's custom-code slot. Replace anything that is wrong.

- **Menu or price list is an HTML page.** Agents can read items and prices directly.
- **Booking on your own site.** Agents can book without a marketplace in the loop.
