EasyPost

EasyPost is a shipping API platform aimed at developers who need to embed shipping label generation, rate comparison, tracking, and address verification directly into their own software products, rather than a merchant-facing shipping tool used directly by a single business's operations team. Its API abstracts away the complexity of integrating separately with dozens of different carriers, each with its own quirks and data formats, giving developers one consistent interface to generate a shipping label or retrieve a tracking update regardless of which underlying carrier is actually fulfilling that shipment. This makes EasyPost a common infrastructure choice for software platforms that need shipping functionality as a feature within a broader product, such as a marketplace platform that needs sellers to be able to print shipping labels, or a warehouse management system that needs to compare rates across carriers automatically as part of its fulfillment logic. EasyPost's tracking API normalizes tracking status updates across carriers into a consistent format and can trigger webhooks when a shipment's status changes, letting a platform update its own customers automatically rather than requiring manual status checks. Address verification tools catch invalid or undeliverable addresses before a label is even purchased, reducing costly failed delivery attempts. EasyPost is used by software companies and platforms building shipping and logistics functionality into their own products, rather than businesses looking for a direct, standalone shipping tool for their own single operation.
