A Common Data Environment (CDE) in a construction project is a centralized digital platform that facilitates the collection, management, and sharing of data and information among all involved in the project. The OpenCDE standard is a set of APIs that provide access to and management of data and information within a CDE.

Catenda provides a set of OpenCDE compliant APIs. The OpenCDE Foundation API includes a small number of services that are common to all OpenCDE APIs.

OpenCDE endpoints are available under the `https://api.catenda.com/opencde/` path.
