List available document templates

Last updated Jun 14, 2026

Query Parameters

kindstringOptional

The Document.type value to filter by (e.g. safe, bylaws). Multiple templates can share the same kind (variants).

categorystringOptional

One of"formation""financing""commercial""governance""tax"

availabilitystringOptional

Filter by availability. When omitted, the list returns ga and preview templates only — revisions superseded by a catalog re-ingest (deprecated) or withdrawn (retired) stay out of the default listing but remain reachable with an explicit filter, and documents rendered from them keep re-rendering against their pinned revision.

One of"preview""ga""deprecated""retired"

attachable_tostringOptional

Filter to templates that can attach to a given parent template_id. Useful for picking children in attachment grammars (Pro Rata Side Letter → SAFE, MFN amendment → SAFE, DPA/SLA/BAA → CSA).

Response Body

List templates.

List the Matter-authored templates generateDocument can render against entity state. Filter by kind (the Document.type value the template produces), category (formation | financing | commercial | governance | tax), availability (preview | ga | deprecated | retired — defaults to ga only when omitted), and attachable_to (parent template_id, for picking attachable children like Pro Rata Side Letters). Cursor-paginated.

The v1 catalog ships 22 governance-category templates covering the board-and-stockholder consent surface — the Day-0 organizational consent, officer/director-change cascades, substance-specialized manage-phase and exit-phase board consents, a board-side general catch-all, and stockholder-side parallels for the actions that statutorily require both. The catalog is sourced from the x-matter-template-catalog block at the top level of this spec. Other categories (formation, financing, commercial, tax) ingest through separate workstreams.
