Authorizations

Authorization

string

header

required

Every request authenticates with an API key: Authorization: Bearer {API_KEY}. App endpoints take an app API key; knowledge endpoints take a knowledge base API key (Get Started).

Keep keys server-side; never embed them in client code. Requests with a missing or invalid key fail with HTTP 401 (unauthorized).

Body

application/json

name

string

required

Name of the knowledge base.

Required string length: 1 - 40

description

string

default:""

Description of the knowledge base.

Maximum string length: 400

indexing_technique

enum<string> | null

high_quality uses embedding models for precise search; economy uses keyword-based indexing.

Available options:

high_quality,

economy

permission

enum<string>

default:only_me

Controls who can access this knowledge base. only_me restricts to the creator, all_team_members grants access to the entire workspace, partial_members grants access to specified members.

Available options:

only_me,

all_team_members,

partial_members

provider

enum<string>

default:vendor

vendor for internal knowledge base, external for external knowledge base.

Available options:

vendor,

external

embedding_model

string

Embedding model name. Use the model field from Get Available Models with model_type=text-embedding.

embedding_model_provider

string

Embedding model provider identifier, formatted as organization/plugin_name/provider_name (e.g. langgenius/openai/openai). A bare name like openai expands to langgenius/<name>/<name> and works only for langgenius-published plugins.

Get valid values from the provider field of Get Available Models with model_type=text-embedding.

retrieval_model

object

Retrieval model configuration. Controls how chunks are searched and ranked when querying this knowledge base.

Show child attributes

external_knowledge_api_id

string

ID of the external knowledge API connection.

external_knowledge_id

string

ID of the external knowledge base.

summary_index_setting

object | null

Summary index configuration.

string

Provider type. vendor for internally managed, external for external knowledge base connections.

permission

string

Controls who can access this knowledge base. Possible values: only_me, all_team_members, partial_members.

data_source_type

string

Data source type of the documents, null if not yet configured.

indexing_technique

string

high_quality uses embedding models for precise search; economy uses keyword-based indexing.

app_count

integer

Number of applications currently using this knowledge base.

document_count

integer

Total number of documents in the knowledge base.

word_count

integer

Total word count across all documents.

created_by

updated_at

number

Last update timestamp (Unix epoch in seconds).

embedding_model

string

Name of the embedding model used for indexing.

embedding_model_provider

string

Embedding model provider identifier, formatted as organization/plugin_name/provider_name (e.g. langgenius/openai/openai). Legacy knowledge bases may return the bare short form (e.g. openai).

embedding_available
