Replace optin

Sets the signed-in caller's OWN opt-in to public betas: on, every public beta and each one promoted later is on for them; off, none is.

Address	`https://api.hanzo.ai/v1/flag/optin`
Method	`PUT`
Operation	`put_flag_optin`
Auth	`Authorization: Bearer $HANZO_API_KEY`

Sets the signed-in caller's OWN opt-in to public betas: on, every public beta and each one promoted later is on for them; off, none is. Self only: the row written is the caller's validated subject, whatever the request says. Opting in while the org they act in blocked it is refused; opting out never is.

Request

1 field, body application/json (required).

Field	In	Type	Required	Description
`on`	body	boolean	—	On opts the caller in to every public beta, current and future, when true, and out when false.

Response

Status	Body	Meaning
`200`	flag.optinOut	ok
`default`	problem-details	refused

200 body — 3 fields.

Field	In	Type	Always	Description
`blocked`	body	boolean	—	Blocked is true when the org the caller acts in turned the opt-in off for its members.
`on`	body	boolean	—	On is true when the caller opted in: every public beta, and each one promoted later, is on for them unless Blocked.
`public`	body	string[]	—	Public is the id of every beta anyone may opt in to (beta.<id>).

Failure carries the platform error shape — see Errors.

MCP reaches flag through the flag tool, which names its 12 operations with its own verbs — this one among them, under a name only MCP declares. describe explains any of them:

curl -X POST https://api.hanzo.ai/v1/mcp \
  -H "Content-Type: application/json" \
  -d '{
       "jsonrpc": "2.0",
       "id": 1,
       "method": "tools/call",
       "params": {
         "name": "describe",
         "arguments": {
           "op": "get_flag_activity"
         }
       }
     }'
