The Pinecone Nexus API gives you programmatic access to the same operations available in the Nexus console: managing contexts and sources, running curation, and querying with KnowQL. Anything you can do in the console you can do through the API. It also covers workspace lifecycle, which you otherwise manage in the Pinecone console. The API spans two planes, each with its own base URL and authentication:
  • Control plane manages workspace lifecycle and is served by Pinecone globally.
  • Data plane handles contexts, sources, curation, and KnowQL queries, and is served by your deployment’s workspace host.

Base URLs

​
Control plane

Workspace management is served by Pinecone globally:

​
Data plane

Contexts, curation, and queries are served by your deployment’s workspace host, from the nexus_default_workspace_data_console_url output of the install, with the /api path:

Versioning

Nexus uses date-based versioning through the X-Pinecone-Api-Version header. Send the version you built against, for example 2026-07. Omit it to use the default version. The older /api/v0 path stays functional as a legacy alias.
