This site contains a collection of useful tools and API's for software developers and hobbyists.
API.Toys offers free and low-cost API's for a number of of different tasks. The enclosed API endpoints are intended for development and testing. These endpoints may also be used for production provided the consumption is low - you should cache responses and query as infrequently as possible.
The Basic API contains some very basic useful features for developers. Do things like convert time, do virtual dice rolls, generate random phrases... This is a growing list of useful and nonsensical API endpoints.
All calls under this API are free. Just don't abuse them!
