    "Supply your ed25519 public key on first request — becomes your agent_id and account key" (agent card identity block,
    pubkey_exchange: true). There is no signup, no API key issuance and no OAuth flow: the calling agent's Ed25519 public key
    is its account identifier; the free tier is rate-limited per key and paid credit (satoshis over Lightning, when it opens)
    is presumably attached to the same key. The card does not state which header or JSON-RPC field carries the key or
    whether requests must be signed — that detail requires the (404) GitHub repository or a live paid session, neither of
    which was reachable.
