Create a knowledge base

Create a new knowledge base in the authenticated user’s organization.

Required fields:

• name — must be unique within the organization
• embeddingModel — the model used to generate embeddings (e.g., openai:text-embedding-3-small)

Optional features:

• source — marks the KB as integration-managed (disables manual file upload in UI)
• trigger — automatically runs an agent when new files are added
• extractionModel / extractionSchema — structured data extraction from uploaded files

Authorizations

Authorization · string · header · required

JWT token from Clerk authentication.

Must be from a user with org:admin role.

Body

application/json

name · string · required

Name of the knowledge base (must be unique within the org)

Example:

"Product Documentation"

embeddingModel · string · required

Embedding model identifier (e.g., openai:text-embedding-3-small)

Example:

"openai:text-embedding-3-small"

description · string | null

Optional description

Example:

"All product docs and user guides"

extractionModel · string | null

Optional model for structured data extraction from files

extractionSchema · object

JSON schema defining what structured data to extract from files

source · string | null

Integration source identifier. When set, the KB becomes integration-managed — manual file upload/deletion is disabled in the UI, but API access remains unrestricted.

Example:
