What this server can do

3 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.

check_retailer_trust(retailer)
Get value.us's proprietary VUS score (0-5) for a retailer and when its data was last verified. The VUS score measures how much current, verified data value.us holds on the store (a data-confidence signal) - it is NOT a verdict on whether the store is trustworthy or safe to buy from. Required: retailer.
find_deals(limit, intent, country)
Find online retailers that currently have a specific kind of verified deal or policy, ranked. Use for questions like 'who has free shipping', 'which stores give a student discount', or 'what's on sale now'. Required: intent.
lookup_retailer(retailer)
Look up verified deals and store policies for a specific online retailer: signup/newsletter offer, free-shipping threshold, return window, price-match, gift cards, student/military discounts, current sale, and the value.us VUS score (our data-confidence rating). Input a store name or domain. Required: retailer.

Signals

These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.
