    The public Aleo node REST API (api.explorer.provable.com) is unauthenticated.
    Read endpoints (chain state, blocks, transactions, programs, mappings,
    committee) require no API key, token, or credential. Write access is not
    granted via HTTP auth — the POST /transaction/broadcast endpoint accepts a
    transaction that is already cryptographically signed with the sender's Aleo
    private key (the on-chain authorization model), so authorization is enforced
    by zk-proof and signature validation at the protocol layer, not by API
    credentials. Aleo accounts are keypairs (private key / view key / address)
    generated with the Provable SDK or the Leo CLI account commands.
schemes: []
account_model:
  identity: Aleo account keypair (APrivateKey / AViewKey / aleo1... address)
  signing: Transactions are authorized and signed with the account private key via snarkVM / the Provable SDK before broadcast.
