Facets

List content types

List your classification trees: the content types you’ve adopted from the starter templates or created from scratch. This is where you see what’s available to classify your documents with.

Content types are tree-based. Each tree is an independent classification hierarchy (e.g., legal → contract → nda). You can have multiple trees side by side (legal, finance, compliance), and a single document can be classified under multiple trees simultaneously. For instance, a contract can be both legal:contract:nda and finance:investment:term-sheet.

Each node in the tree can carry custom attributes (metadata fields like jurisdiction, effective_date, contract_value). Attributes are inherited down the tree: a document at legal:contract:nda gets attributes from all three levels.

New here? Start by browsing available templates at GET /api/v3/content-types/templates, then adopt the ones you need via POST /api/v3/content-types {"action": "adopt"}.

Query params:

?query=5G antennas: filter to content types relevant to a search query (uses a first-pass retrieval). Without this param, the full catalog is returned.
?path=legal: filter to a specific subtree
?path=legal,finance: multiple subtrees (comma-separated)
?depth=0: roots only. ?depth=N: N levels of children.
?include_attributes=true (default): include attribute definitions per node
?include_attributes=false: omit attribute definitions for a lighter response

query and path can be combined: returns the intersection (only matched content types under the requested paths).

Returns an empty list if no content types have been set up yet.
