Address	`https://api.hanzo.ai/v1/iam/auth/identifier`
Method	`POST`
Operation	`post_iam_auth_identifier`
Auth	`Authorization: Bearer $HANZO_API_KEY`

Answers whether an account holds an email address at an application, and whether that account signs in with a password. Only an application that registers strangers answers, since its signup says as much already. The address is resolved exactly as sign-in resolves it, so the screen and the sign-in cannot disagree. A client asking faster than a person types is refused with 429.

MCP reaches iam through the iam tool, which names its 44 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": "list_iam_applications"
         }
       }
     }'
