    The Overlay public market-data API requires no authentication — the docs
    state the endpoints are public. Trading actions are authorized on-chain by
    the wallet signing BSC transactions (chain id 56), not by an API credential.

    build/unwind transactions are signed by the trader's wallet and executed
    against the Shiva trading contract (0xeB497c228F130BD91E7F13f81c312243961d894A)
    on BSC. The published agent skill recommends a smart-contract account with
    restricted permissions (Safe + Zodiac Roles) rather than a raw private key.
