get_v1_captable_rounds_id
GetRound returns one of the caller org's fundraising rounds together with every investment written into it, oldest first.
GetRound returns one of the caller org's fundraising rounds together with every investment written into it, oldest first. A round id that does not exist in the caller's org is not found — including one that exists in another tenant, since the org comes from the caller's principal and is part of the lookup.

Arguments
| Field | Type | Required | Default | Description |
|---|---|---|---|---|
id | string | — | — | ID is the round to read. It is the path segment: the URL is the addressing authority, and the org it is resolved in comes from the caller's principal, so an id from another tenant is simply not found. |
This tool's schema does not declare which fields are required, nor any default, nor any enumerated value set. The columns above are empty because the door publishes nothing there, not because the answer is "none" — where a field is constrained, the constraint is stated in that field's own description.
Call it
A tools/call carries every argument in one flat object — nothing binds to a path or a query string. Every declared argument is shown, because the door marks none of them required.
