Address	`https://api.hanzo.ai/v1/link/route`
Method	`GET`
Operation	`get_link_route`
Auth	`Authorization: Bearer $HANZO_API_KEY`

Gets the failover order across your linked accounts.

It answers an ordered redundancy plan over the caller's LINKED (not revoked) accounts: each candidate with its remaining rate-limit headroom, whether it is routable right now, how it BILLS (plan or commerce), and a reason when it is not — plus the primary to try first. It is what lets a router fail over from one subscription to another and fall back to the metered API as the always-available backstop, knowing the cost consequence before it dials.

It is POLICY, not execution: the plan is computed purely from the usage snapshots already in the registry, never by probing a provider, so it is a total function of the links and costs nothing to ask for. Actually dialing, detecting a live 429 and advancing to the next candidate belongs to the caller. A link with no snapshot counts as full headroom.

Request

GET /v1/link/route takes no parameters and no body — the credential is the whole request.

Response

Status	Body	Meaning
`200`	link.RoutePlan	ok
`default`	problem-details	refused

200 body — 25 fields.

Field	In	Type	Always	Description
`candidates`	body	link.RouteCandidate[]	—	Candidates is every linked account in preference order: subscriptions first, then metered api-key accounts as the backstop.
`candidates[].account`	body	string	—	Account is the provider-side account identifier.
`candidates[].available`	body	boolean	—	Available reports whether the candidate is routable right now.
`candidates[].billing`	body	string	—	Billing is the cost consequence of dialing this candidate: plan (the user's own subscription) or commerce (the metered gateway path).
`candidates[].headroomPct`	body	number (double)	—	HeadroomPct is the remaining rate-limit capacity, 0..100.
`candidates[].host`	body	string	—	Host is that machine's hostname label.
`candidates[].kind`	body	string	—	Kind is how the account authenticates: subscription or apikey.
`candidates[].linkId`	body	string	—	LinkID is the underlying link's opaque handle.
`candidates[].machine`	body	string	—	Machine is the machine the account is signed in on.
`candidates[].plan`	body	string	—	Plan is the provider plan label the account is on.
`candidates[].provider`	body	string	—	Provider is the AI provider the candidate account belongs to.
`candidates[].reason`	body	string	—	Reason says why the candidate is not routable, when Available is false.
`generatedAt`	body	string	—	GeneratedAt is when the plan was computed, RFC 3339 UTC.
`primary`	body	link.RouteCandidate	—
`primary.account`	body	string	—	Account is the provider-side account identifier.
`primary.available`	body	boolean	—	Available reports whether the candidate is routable right now.
`primary.billing`	body	string	—	Billing is the cost consequence of dialing this candidate: plan (the user's own subscription) or commerce (the metered gateway path).
`primary.headroomPct`	body	number (double)	—	HeadroomPct is the remaining rate-limit capacity, 0..100.
`primary.host`	body	string	—	Host is that machine's hostname label.
`primary.kind`	body	string	—	Kind is how the account authenticates: subscription or apikey.
`primary.linkId`	body	string	—	LinkID is the underlying link's opaque handle.
`primary.machine`	body	string	—	Machine is the machine the account is signed in on.
`primary.plan`	body	string	—	Plan is the provider plan label the account is on.
`primary.provider`	body	string	—	Provider is the AI provider the candidate account belongs to.
`primary.reason`	body	string	—	Reason says why the candidate is not routable, when Available is false.
