Data Science Toolkit is a very original resource which provides free access to various valuable data like:
- street address to coordinates
- ip address to coordinates
- file to text (converts PDFs, Word docs, Excel spreadsheets to text)
- and much more.
These data can be reached via the API provided or every part of it is offered as a ready-to-install VM (virtual machine) where you can install to any server (or locally) for limitless API usage.
Also, besides the VM, an EC2 AMI is ready for instant deployment to the Amazon's cloud.
