# BuyWise

> BuyWise gives shoppers and shopping assistants trust signals about brands and product listings: what kind of brand it is, its reputation and usual price positioning, and, for a listing, whether it looks generic white-label, how its quality, price, discount claims, reviews and seller look. Every finding carries a confidence; BuyWise never says buy or don't buy.

## For AI assistants and agents

- [OpenAPI schema](https://api.buywise.fyi/openapi.json)
