get_v1_marketing_unsubscribe
Is the PUBLIC one-click endpoint (no principal): a recipient clicks the signed link in an email footer.
Is the PUBLIC one-click endpoint (no principal): a recipient clicks the signed link in an email footer. The token binds (org, channel, address), so a caller can only opt OUT exactly the tuple it was minted for — never another address and never another org. An invalid token is refused, and a deployment with no KMS-sealed key refuses rather than accepting anything.

Arguments
| Field | Type | Required | Default | Values | Description |
|---|---|---|---|---|---|
address | string | — | — | — | Address is the recipient to opt out. |
channel | string | — | — | — | Channel is the surface to opt out of. |
org | string | — | — | — | Org is the org the link was minted for. |
token | string | — | — | — | Token is the HMAC over (org, channel, address). It is the ONLY authority here — there is no principal — so it binds the request to one tuple and nothing else. |
tools/list declares a type and a description for each field and nothing further. A — means neither the door nor that operation constrains the field.
Call it
A tools/call carries every argument in one flat object — nothing binds to a path or a query string. Nothing above is required, so every declared argument is shown rather than a guess at which matter.

}'Values are the operation's own defaults and enumerated values where it declares them, and a <placeholder> where neither source declares one. tools/list needs no credential; tools/call does — called without one the door answers HTTP 200 with a JSON-RPC result whose isError is set and whose text says what was missing.
