Overview
1Shot API is an onchain automation layer that turns smart contracts into easily callable tools for apps, workflows, and AI-driven systems. It provides managed wallets, transaction orchestration, and support for standards like x402 payments and MetaMask Delegation Framework, so you can send stablecoin payments, automate onchain actions, and trigger transactions from platforms like n8n, Make, and IFTTT. Developers can read and write to any supported EVM smart contract, estimate gas, batch calls, and receive webhooks when transactions are finalized. 1Shot Prompts adds annotated smart contract prompts that make it easier for AI systems to reason about contract methods, enabling safer, autonomous onchain execution.
