Method	`POST`
Operation	`post_link`
Auth	`Authorization: Bearer $HANZO_API_KEY`

Registers a signed-in AI provider account on a machine.

It records that a developer has signed into one provider account on one machine — a Claude Max or ChatGPT Plus subscription, a Hanzo key, a raw provider key — and answers 201 with the stored link. Re-reporting the same (machine, provider, account) UPDATES that link rather than creating a second, so a collector may call this on every heartbeat. machine and provider are required (400 otherwise), as is a valid kind, and every field is length-bounded. Scoped to the caller: a validated principal and a non-empty org, else 403, so a caller writes only their OWN accounts within their own org.

Request

8 fields, body application/json (required).

Field	In	Type	Required	Description
`account`	body	string	—	Account is the provider-side account identifier.
`host`	body	string	—	Host is the machine's human hostname label.
`kind`	body	string	—	Kind decides how the account's inference BILLS and defaults to subscription: a subscription account bills the user's own monthly plan and is metered here for visibility only, while an apikey account bills through commerce on the gateway path.
`machine`	body	string	—	Machine is the stable machine identifier.
`os`	body	string	—	OS is the machine's operating system label.
`plan`	body	string	—	Plan is the provider plan label (e.g. "Claude Max").
`provider`	body	string	—	Provider is the AI provider the account belongs to.
`usage`	body	any	—	Usage is an optional usage snapshot, clamped and re-serialized to known fields; omitting it keeps the last good one.

Response

Status	Body	Meaning
`201`	link.linkView	created
`default`	problem-details	refused

201 body — 15 fields.

Field	In	Type	Always	Description
`account`	body	string	—	Account is the provider-side account identifier, when the collector knows it.
`billing`	body	string	—	Billing is how this account's inference bills — plan (the user's own subscription, metered here for visibility only) or commerce (the gateway path).
`createdAt`	body	string	—	CreatedAt is when the link was first registered, RFC 3339 UTC.
`host`	body	string	—	Host is the machine's human hostname label, from its most recent report.
`id`	body	string	—	ID is the link's opaque handle ("link_" + 32 hex chars).
`kind`	body	string	—	Kind is how the account authenticates: subscription or apikey.
`lastSeen`	body	string	—	LastSeen is when the account last reported, RFC 3339 UTC.
`machine`	body	string	—	Machine is the stable machine identifier the collector reports.
`os`	body	string	—	OS is the machine's operating system label.
`plan`	body	string	—	Plan is the provider plan label (e.g. "Claude Max").
`provider`	body	string	—	Provider is the AI provider this account belongs to (claude, openai, hanzo…).
`status`	body	string	—	Status is linked or revoked.
`updatedAt`	body	string	—	UpdatedAt is when the link was last refreshed, RFC 3339 UTC.
`usage`	body	any	—	Usage is the last good usage snapshot, clamped and re-serialized to known fields at ingest.
`user`	body	string	—	User is the owning subject — the validated caller who registered the link.

Failure carries the platform error shape — see Errors.

MCP reaches link through the link tool, which names its 11 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_links"
         }
       }
     }'
