Data Source
A lot of new sources of free, public data have emerged over the last few years, and this
guide covers some of the most useful. It’s aimed at developers looking for information
to supplement their own tools or services. There are obviously a lot of APIs out there,
so to narrow it down to the most useful, the ones in this guide have to meet these
standards:
Free or self-service signup
Traditional commercial data agreements are designed for enterprise companies, so
they’re very costly and time-consuming to experiment with. APIs that are either
free or have a simple sign-up process make it a lot easier to get started.
Broad coverage
Quite a few startups build infrastructure and then hope that users will populate it
with data. Most of the time, this doesn’t happen, so you end up with APIs that
look promising on the surface but actually contain very little useful data.
Online API or downloadable bulk data
Most of us now develop in the web world, so anything else requires a complex
installation process that makes it much harder to try out.
Linked to outside entities
There has to be some way to look up information that ties the service’s data to the
outside world. For example, the Twitter and Facebook APIs don’t qualify because
you can only find users by internal identifiers, whereas LinkedIn does because you
can look up accounts by their real-world names and locations.
