Address	`https://api.hanzo.ai/v1/validator`
Method	`POST`
Operation	`post_validator`
Auth	`Authorization: Bearer $HANZO_API_KEY`

Claims a validator slot and provisions its node, after proving the caller's wallet owns the slot's NFT.

The pipeline, all server-enforced: burn the single-use challenge (so a replayed or forged nonce dies before any chain read), recover the signer from the message this server rebuilds, require that wallet to hold Validator-tier GenesisNFT #tokenId on Ethereum mainnet, generate a fresh luxd staking identity and seal it into KMS, write a LuxNetwork CR for a NEW node, and ENQUEUE an owner-gated registration. The registration is never auto-submitted to any P-Chain — the owner co-signs it out of band — and the stake weight is set at co-sign time, never derived from the NFT.

It fails CLOSED at every gate: a bad signature, a non-owner, a non-tier slot or an unavailable KMS all leave no claim persisted and no key material exposed. Re-claiming a slot this org already holds re-applies the node CR and returns 200 with the existing identity (keys and NodeID are stable); a slot held by another org is 409. A cluster-less deployment still claims the slot, seals the keys and queues the registration, reporting the node as "node_pending".

Request

3 fields, body application/json (required).

Field	In	Type	Required	Description
`nonce`	body	string	—	Nonce is the value GET /v1/validator/challenge issued for this slot.
`signature`	body	string	—	Signature is the wallet's personal_sign over the challenge message, hex with a 0x prefix.
`tokenId`	body	integer (uint64)	—	TokenID is the Validator-tier GenesisNFT token id being claimed.

Response

Status	Body	Meaning
`200`	validator.slotView	ok
`default`	problem-details	refused

200 body — 15 fields.

Field	In	Type	Always	Description
`blsPubkey`	body	string	—	BLSPubkey is the node's BLS public key, hex.
`crName`	body	string	—	CRName is the LuxNetwork custom resource that materializes the node.
`createdAt`	body	integer (int64)	—	CreatedAt is when the slot was first claimed, as a Unix timestamp.
`namespace`	body	string	—	Namespace is the Kubernetes namespace the node's CR lives in.
`network`	body	string	—	Network is the luxd network slug the node joins.
`nodeID`	body	string	—	NodeID is the luxd node id derived from the sealed staking identity.
`nodeStatus`	body	string	—	NodeStatus is the provisioning state of the node: "node_created" once the CR is applied, "node_pending" when no cluster is reachable (the slot is still claimed and the keys are still sealed).
`registration`	body	validator.registrationView	—
`registration.id`	body	string	—	ID is the registration's handle.
`registration.nodeID`	body	string	—	NodeID is the luxd node the registration is for.
`registration.status`	body	string	—	Status is the registration's lifecycle state; "pending_owner_approval" until the owner co-signs it out of band.
`slot`	body	integer (uint64)	—	Slot is the validator slot number — the same value as tokenId, under the name the portal reads.
`tokenId`	body	integer (uint64)	—	TokenID is the GenesisNFT token id that IS this slot.
`updatedAt`	body	integer (int64)	—	UpdatedAt is when the slot last changed, as a Unix timestamp.
`wallet`	body	string	—	Wallet is the lowercase Ethereum address that proved ownership of the NFT.

MCP reaches validator through the validator tool, which names its 4 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_validators"
         }
       }
     }'
