Crawling API
SeekStorm is a Search as a Service.

Your organization has millions or billions of documents, at different locations, with thousands of concurrent users who need results within milliseconds, reflecting the latest changes in real-time? Add our turn-key search solution to your application with just two lines of code. Provide the documents or data you want to index via REST search API, and search them instantly in real-time. Don't worry about scalability and performance, we do all the heavy lifting for you.
