PUT /v1/captable/company

Captable → · All API references → · Get started →

Address	`https://api.hanzo.ai/v1/captable/company`
Method	`PUT`
Operation	`put_captable_company`
Auth	`Authorization: Bearer $HANZO_API_KEY`

Sets the caller org's company name and incorporation details. The name is required; the three incorporation fields are optional and each is stored as empty when omitted, so a call that sends only a name CLEARS them. The company row itself is seeded when the tenant's store first opens, so this never creates one.

Request

4 fields, body application/json (required).

Field	In	Type	Required	Description
`incorporationCountry`	body	any	—	IncorporationCountry is the ISO country the entity is incorporated in.
`incorporationState`	body	any	—	IncorporationState is the state or province of incorporation.
`incorporationType`	body	any	—	IncorporationType is the entity kind, e.g. LLC or C_CORP.
`name`	body	any	—	Name is the company's legal name.

Response

Status	Body	Meaning
`200`	captable.captableUpdated	ok
`default`	problem-details	refused

200 body — 2 fields.

Field	In	Type	Always	Description
`message`	body	string	—	Message is the human sentence the cap table wrote, e.g. "Company updated".
`success`	body	boolean	—	Success is true when the update was applied.

Failure carries the platform error shape — see Errors.

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"
         }
       }
     }'
