History Delivered

APIzen.Date is a simple API that can be used to fetch historical events into JSON format. While it's not hard to find a "on this day" API, most of them require registration or just plain suck. Our API makes development quick and to the point.

No API Key Required

The OTD-API can be used free of charge but you may not use this service in a manner that exceeds reasonable request volume. When no API key is provided, attribution is required and the number of requests per IP address is limited.
