    thirdweb provides a unified interface for Web3 development. This
    specification documents real, publicly documented HTTP endpoints across the
    thirdweb unified API (api.thirdweb.com - wallets, transactions, contracts,
    tokens, payments and bridge), Engine (backend transaction execution),
    Insight (indexed on-chain data) and Nebula (AI blockchain interface).
    Authenticate frontend usage with an x-client-id header (plus x-bundle-id for
    native apps) or a Bearer JWT, and backend usage with an x-secret-key header.
