API · Manage · Entities
Retrieve the document vault.
One read returns every artifact the entity has ever produced, grouped by kind and decorated with the layperson explainer + signing/filing state the dashboard needs. Designed for the founder's "show me everything you have on file" question — every Document, Filing, Certificate, EIN confirmation, signed agreement, processor TOS, and any item with a public-record analogue is enumerated here with a download/review URL.
Resources surfaced:
- Formation artefacts: Certificate of Incorporation, EIN confirmation letter, bylaws, organisational consent, stock purchase agreements, §83(b) elections, indemnification agreements, registered- agent appointment. - Compliance artefacts: every accepted Filing (DE annual report, franchise-tax confirmations, BOI reports, Form 1120 filings). - Commercial artefacts: every customer contract, supplier agreement, payment-processor TOS, and licence document. - Equity artefacts: every executed SAFE / convertible, side letter, option grant, board resolution authorising issuance. - Public-record passthroughs: any document Matter retrieved from a state or federal authority on the entity's behalf (Certificate of Good Standing, certified copies of state filings).
The view never deletes, never mutates — it's a single read endpoint that the dashboard uses to render the founder's "all your documents" page. Document content is not embedded; each entry carries a download_url (signed, short-lived) and a review_url (long-lived, dashboard-rendered). Use ?expand[]=items.signing_status for the signed/pending breakdown.

Query Parameters
filter_kindstringOptionalNarrow the vault to a single category. Equivalent to filtering on
items[].category. The default all returns the full vault.
"formation""compliance""commercial""equity""public_record""all"include_draftsbooleanOptionalInclude items in draft execution_status. Defaults to false —
most callers want only items that exist as a fact (sent,
partially_signed, executed, or for Filings, submitted,
accepted).
