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

FieldTypeRequiredDefaultValuesDescription
addressstringAddress is the recipient to opt out.
channelstringChannel is the surface to opt out of.
orgstringOrg is the org the link was minted for.
tokenstringToken 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.

curl -X POST https://api.hanzo.ai/v1/mcp \
  -H "Authorization: Bearer $HANZO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
       "jsonrpc": "2.0",
       "id": 1,
       "method": "tools/call",
       "params": {
         "name": "get_v1_marketing_unsubscribe",
         "arguments": {
           "address": "<address>",
           "channel": "<channel>",
           "org": "<org>",
           "token": "<token>"
         }
       }
     }'

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.
