Address	`https://api.hanzo.ai/v1/captable/classes`
Method	`GET`
Operation	`get_captable_classes`
Auth	`Authorization: Bearer $HANZO_API_KEY`

Returns the caller org's share classes, in creation order. A share class is what a certificate is issued in, and every class the company has authorized appears. The response is a bare JSON array, not an envelope.

Request

GET /v1/captable/classes takes no parameters and no body — the credential is the whole request.

MCP reaches captable through the captable tool, which names its 30 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_captable_classes"
         }
       }
     }'
