EasyPost is a multi-carrier rate shopping shipping solution. The EasyPost API is one integration point for 100+ carriers, including USPS. All USPS functionality and pricing are accessible using the EasyPost API. EasyPost standardizes the inconsistencies across carrier APIs with its RESTful interface.
USPS pricing is split four tiers. The tiers are as follows:
Retail is the rate you pay when you purchase postage or parcel at a Post Office, or often at a UPS Store, FedEx, or most retail settings.
Commercial Base Pricing is the next level up. This rate is the same as you'll pay most anywhere online, and has significant savings over Retail.
Commercial Plus Pricing provides even more savings over Commercial Base Pricing, which is the rate we provide to everyone using the EasyPost API.
Negotiated Service Agreement has the highest level of savings on USPS. These are for only the highest volume shippers, and as the name suggests, are negotiated on a per customer basis.
