  title: thirdweb Authentication Transactions API
  description: 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.
