# RateShip

> RateShip is a unified shipping API that queries Shippo, EasyPost, and ShipEngine in parallel through a single endpoint, normalizing rates across providers into a consistent response format.

## About

RateShip lets developers and businesses connect their existing shipping provider accounts (Shippo, EasyPost, ShipEngine) and access all of them through a single API. One API call returns normalized rates from every connected provider, sorted by price. Label purchases go directly to the user's provider account - RateShip never handles shipping money.
