Building an API on open data – GET PUT POST

"Welcome to GET PUT POST, a newsletter all about APIs. Each edition features an interview with a startup about their API and ideas for developers to build on their platform.

[...]

This edition, I spoke with Ed Freyfogle, Co-Founder of OpenCage. Their API makes it easy to turn addresses into coordinates and, unlike Google and others, it’s built on top of a completely open data set. We discuss how the business got started, their stack to fan requests to other services, and scrappy marketing efforts."
