The Dow Jones Industrial Index is a well known indicator of the overall health of the economy calculated using the current value of a variety of stocks along with the 'Dow Divisor'. The opening Dow Jones Industrial Index is used in the Geohashing algorithm.
If you're programming a geohashing calculator, mapping service or other related service, you'll need a source for the current and historic DJI value. This page lists known sources and ways to access them and access restrictions.
Conventions
In the following descriptions, tokens will be used in URLs to represent values of the date as specified on this page on the PHP website. Specifically:
- %Y is the four digit year (Eg, 1990)
- %m is the two digit month number (Eg, 03)
- %d is the two digit day number (Eg, 14)

- Leading zeros are not significant in year, month and day values. If you request a date which has no value it will return the string 'null'. If you would like to avoid it returning 'null' when requesting days such as weekends, you may pass the GET variable 'compensate' with any value, which will cause it to work backwards from any non-existent days until it finds one with a value and return that instead.
- Access Restrictions: Free for anyone to use up to a reasonable volume. If you need to make tens of thousands of requests daily, feel free to contact me and I'll send you a dump of the database and the update script.
