As being the placement coordinator of our college the proycurl helped me a lot its api is easy to integrate and easy to use. I use this to filter out HR contacts through linkedin but it can also be used to filter out data. You will get 10 credit for using api so this is also good. Support team is also very helpful. I mail them for any query and I get the reply very quick.
We offer APIs that enrich profiles with structured data, so that you can build and scale data-driven applications on people and companies with our APIs without worrying about scaling a web scraping and data-science team.
