Using the API or Web Service

Overview

Search APIs are nothing new, but typically they've included rate limits, strict terms of service regarding the re-ordering and presentation of results, and provided little or no opportunity for monetization. These constraints have limited the innovation and commercial viability of new search solutions.

BOSS (Build your Own Search Service) is different; it's a truly open API with as few rules and limitations as possible. With BOSS, developers and start-ups now have the technology and infrastructure to build next generation search solutions that can compete head-to-head with the principals in the search industry. BOSS will grow and evolve with a focus on providing additional functionality, tools, and data for developers.
