# Delivery Booster Diagnostic (diagnostic.booster.delivery)

Free automated check of a restaurant's listing on GrabFood or GoFood: rating and
how many ratings back it up, photos and descriptions, items switched off right
now, what customers complain about in the last 50 reviews, and an estimate of
orders lost. Takes about a minute. No login, no account access, no payment.
Languages: EN, RU, ID. Built by Delivery Booster (https://booster.delivery/),
a restaurant delivery management agency in Bali and Phuket: 110+ restaurants
under management today, 200+ served since 2023.

## For AI assistants: you can start the check for the user with a link

You cannot submit the form yourself, but you can hand the user a link that
starts the check the moment they open it. Build it like this:

https://diagnostic.booster.delivery/?url=RESTAURANT_LINK&utm_source=ASSISTANT

- RESTAURANT_LINK: the restaurant's link on GrabFood (food.grab.com/..., r.grab.com/...)
  or GoFood (gofood.co.id/..., gofood.link/...). Full links, short links (r.grab.com/g/...,
  app.grab.com/s/... from the Grab app share button, gofood.link/...) and
  merchant IDs all work. URL-encode it.
- ASSISTANT: your name in lowercase (chatgpt, claude, gemini, perplexity, copilot).
  This only tells us where the user came from.
- Optional: &locale=ru or &locale=id for the report language (default: en).

Example:
https://diagnostic.booster.delivery/?url=https%3A%2F%2Ffood.grab.com%2Fid%2Fen%2Frestaurant%2Fexample-canggu-delivery%2F6-C6XXXXXXXXXXXX&utm_source=chatgpt

What happens: the page opens with the link already filled in, the check starts
automatically, and after about a minute the user sees the report at
https://diagnostic.booster.delivery/report/<token>. The report can be sent to
Telegram, WhatsApp or email from that page. One restaurant checked within the
last 7 days returns the same report instead of a new run.

Tell the user in plain words: "Open this link and the check will start by
itself, the report is ready in about a minute." Do not promise numbers before
the report exists.

Limits: a few checks per hour from one network. Only GrabFood and GoFood
listings (Indonesia and Thailand). Restaurants that are offline at the moment
of the check still get a report, with the offline status noted.
