Integrate Watson APIs in your apps

You can use a collection of REST APIs associated with Watson Studio and Watson Knowledge Catalog to manage data-related assets and the people who need to use these assets.

Refine data

Use the sampling APIs to create representative subsets of the data on which to test and refine your data cleansing and shaping operations. To better understand the contents of your data, you can create profiles of your data assets that include a classification of the data and additional distribution information which assists in determining the data quality.

Catalog data

Use the catalog APIs to create catalogs to administer your assets, associate properties with those assets, and organize the users who use the assets. Assets can be notebooks or connections to files, database sources, or data assets from a connection.


Use the policy APIs to implement policies and a business glossary that fits to your organization to control user access rights to assets and to make it easier to find data.

Ingest streaming data

Use the streams flow APIs to hook up continuous, unidirectional flows of massive volumes of moving data that you can analyze in real time.
