FirstKey

Generate a fresh Ed25519 wallet for an AI agent: returns the ICP principal and the PKCS#8 PEM private key. The private key is returned exactly once over this call and is never stored anywhere. No signup, no on-chain registration — the keypair IS the wallet.

Claim the one-time free 1T cycles grant from the FirstKey faucet for an agent principal. One claim per principal, ever. The grant lands on the cycles ledger and funds the agent's first canister deploy.

{
  "type": "object",
  "properties": {
    "agent": {
      "description": "The agent's ICP principal (text form) receiving the grant.",
      "type": "string"
    }
  },
  "required": [
    "agent"
  ]
}

Deploy a static website for an agent: creates a canister on the Internet Computer, installs the FirstKey static host, uploads every file, and returns the live https URL. The agent is added as a controller of its site canister. One free deploy per agent principal, funded from the FirstKey deploy pool; files must fit in one call (total under ~1.4 MB decoded) — use deploy_upload_chunk for larger files.

Upload one chunk of a large file to an already-deployed agent site (for files that don't fit in a single deploy_site call). Chunks are appended in order; set is_last on the final chunk to publish the file.

Get the FirstKey Fuel payment link for a principal: a human pays by card (Stripe) and cycles land in the agent's wallet — the sovereign refuel path when the free faucet grant or deploy pool is exhausted.

    "principal": {
      "description": "The agent's ICP principal to refuel.",
      "type": "string"
