Baidu API

Baidu Search Marketing Service API provides a suite of web services that allow developers to interact with Baidu servers directly by API. Based on API, developers can build their own applications to manage their search marketing accounts.

The Baidu Search Marketing Service API is mainly designed for major user and third parties, including SEM, agencies, and other online marketing experts who manage multiple client accounts and/or large campaigns.

Please note that while Baidu has extensive documentation in English, the rest of their site is in Chinese.
