Wolfram|Alpha is a "computational knowledge engine" whose long-term goal is "to make all systematic knowledge immediately computable and accessible to everyone. We aim to collect and curate all objective data; implement every known model, method, and algorithm; and make it possible to compute whatever can be computed about anything." It contains 10+ trillion of pieces of data, 50,000+ types of algorithms and models, and linguistic capabilities for 1000+ domains.
The API provides two general classes of queries. At the highest level, you can submit free-form queries like users might enter at the Wolfram|Alpha site itself, and get back full Wolfram|Alpha output in a variety of formats. The second type of query is a lower-level request for a single well-defined result, or range of results, from their entity/property-based data API, such as a caloric value for a food item, or a tide table for a requested location
The following is a list of historical changes that were made to this asset. Typically,
once an API is published on ProgrammableWeb.com, the data we keep about that asset gets updated over the course of its life. For example, the endpoint or home page of the documentation might change.
As a means of enforcing the integrity of our data, every time a non-trivial change is made to the data we keep about an asset,
we require the entry of some changelog text before that change can be saved. This way, we have a great audit trail of all
activity surrounding the asset. For each asset, the changelogs begins with the moment an asset is approved for publication on ProgrammableWeb.
If you spot an error in our data and believe that a record needs to be updated in some way,
the ProgrammableWeb team would very much like to hear from you at email@example.com
