Knowledge bases

List chunks

List document chunks with content search, enabled filtering, sorting, and cursor pagination. Tags use slots; use List tags to resolve display names. Documents that have not finished processing return `409` with their current status. Workspace API keys return `403`; use a personal API key or scoped OAuth token. OAuth scope: `api:read`.
