# Serendipity 3: Agent-Direct Score F (26.2%)

Site: https://serendipity3.com/
Report: https://directindex.org/r/serendipity3.com
Scanned: 2026-10-16 (Provisional: the action test and the assistant citation check still to come; the hatched part of the bar is not measured yet.)
Serendipity 3 is largely invisible to agents.
AI assistants cannot open the website of Serendipity 3, so they rely on what other sites say about it.

## Direct links
- Order directly: https://www.toasttab.com/serendipty-3-e-60th-st/giftcards (through toast acting for the business)
- Menu: https://serendipity3.com/menu/
- Phone: +1 212-838-3531

## What to fix first
- **The site turns every visitor without a browser away, AI agents included.** (+25 points) A plain fetch was refused (challenge:checking your browser); only a real browser got the page. Every AI crawler and agent is turned away the same way, so Reachable scores 0 and the rest is measured on the rendered page. Ask the host to let the AI user agents through. Guide: https://directindex.org/guides/blocking-ai-crawlers-without-knowing
- **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
- **Booking only through resy.** (+5 points) Every agent transaction goes through the marketplace and its commission. Add a direct path on your own site, even a simple form. Guide: https://directindex.org/guides/book-direct-on-your-own-website

## 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.

## Already right
- **robots.txt lets AI crawlers in.** There is no robots.txt, which allows everything.
- **Menu or price list is an HTML page.** Agents can read items and prices directly.
- **Ordering through toast on your own domain.** No marketplace commission, and the guest stays yours.
- **Toast works with agents through its partners.** Toast's guest terms could not be read on 2026-10-15 (bot challenge); since August 2026 Google's Ask Maps completes orders at Toast restaurants through Toast Local under the UCP for Food standard. Read 2026-10-15: https://www.digitaltransactions.net/square-toast-jump-into-ai-boosted-google-maps/. An assistant that is not a partner may not finish the step there; a direct path on your own domain works for all of them.

## Since the scan of 2026-10-14 (F then)
- Fixed: The site could not be read at all
- New: The site turned every visitor without a browser away; No structured data for the business; Booking only through a marketplace
