EasyPost is a multi-carrier shipping solution. The EasyPost API is one integration point for 100+ carriers, including USPS eVS. All USPS eVS functionality is accessible using the EasyPost API. EasyPost standardizes the inconsistencies across carrier APIs with its RESTful interface.
The USPS eVS API is designed for very high-volume package mailers. e-VS, or Electronic Verification System, can be integrated directly through USPS, unlike most other USPS options which require a USPS Provider.
