Happenpappen is partly visible to agents.

## Direct links
- Book directly: https://www.opentable.de/widget/reservation/loader?rid=382014&type=standard&theme=wide&color=1&dark=false&iframe=true&domain=de&lang=de-DE&newtab=false&ot_source=Restaurant%20website&cfe=true (through opentable acting for the business)
- Menu: https://happenpappen.de/#section-menue

## What to fix first
- **No structured data for the business.** (+15 points) Add schema.org JSON-LD for the business (Restaurant, LocalBusiness or the closest type, with name, address, telephone and openingHoursSpecification, plus servesCuisine and acceptsReservations). It is the one block every assistant reads first; the fix kit below has it filled in. 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.

## About

- Website: http://www.happenpappen.de/
- This file follows llms.txt (https://llmstxt.org): a short plain-text description for language models.
```

## Already right
- **robots.txt lets AI crawlers in.** No rule blocks the key AI user agents.
- **AI crawlers get the page.** GPTBot, ClaudeBot and PerplexityBot all received a normal response.
- **Menu or price list is an HTML page.** Agents can read items and prices directly.
- **Booking through opentable on your own domain.** No marketplace commission, and the guest stays yours.
- **OpenTable lets agents act only through its partners.** OpenTable's terms page could not be fetched on 2026-10-15; OpenTable names over 200 authorized partners, Google, Meta and OpenAI among them, as the channels through which agents book. Read 2026-10-15: https://mynews13.com/fl/orlando/business/2026/07/14/opentable-new-terms. An assistant that is not a partner cannot finish the step there; a direct path on your own domain works for all of them.
