About Amazon
Amazon's API ecosystem (api.amazon.com) encompasses the Selling Partner API (SP-API) and Product Advertising API, enabling developers and businesses to automate marketplace operations such as inventory management, order processing, pricing, and fulfillment. The SP-API replaced the older MWS platform and requires an application/approval process. As of January 2026, Amazon charges third-party developers $1,400 annually plus monthly usage fees for SP-API access. The Product Advertising API remains separately governed and is free with rate limits tied to sales volume.
