put_v1_usage_leaderboard_optin

PutUserOptin sets the CALLER's own public-listing preference on the leaderboard. Self only: the row written is keyed by the caller's validated ledger identity, so this can never edit another member's visibility whatever the request says. A caller opting in with no handle is given their username, so a listed row never renders as "Anonymous" to its own owner.

Arguments

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": "put_v1_usage_leaderboard_optin",
         "arguments": {
           "handle": "<handle>",
           "listed": false
         }
       }
     }'

Values are the operation's own defaults and enumerated values where it declares them, and a <placeholder> where neither source declares one. listed holds a stand-in that cannot be spelled that way — JSON gives a number, a boolean and a timestamp no placeholder form — so that value is this page's, not the API's. Neither the door nor the operation 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.

The operation behind it

The same capability over plain HTTP is in the usage API reference, on https://api.hanzo.ai.
