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.

What the evidence says about 1Shot API

1Shot API is on-chain execution infrastructure for agents and applications, not a standalone autonomous agent. It turns configured smart-contract methods into authenticated REST endpoints backed by managed Ethereum-compatible signing wallets.

Last reviewed August 8, 2026

Verified capabilities

  • Managed blockchain wallets

    1Shot provides encrypted Ethereum-compatible signing keys that submit transactions when authenticated API requests invoke configured contract methods.[2]

  • Smart-contract REST endpoints

    Developers configure REST endpoints that read from or write to specific smart-contract methods on supported EVM networks.[1]

  • Transaction status integration

    Configured methods can send transaction-status updates to an optional webhook, and calls can be made through raw HTTP or official client SDKs.[1], [3]

Research coverageExact counts from this profile; bars are relative to the largest count shown.

Where it fits best

  • Developers adding bounded smart-contract reads and writes to an agent or automated workflow through a REST API.[1], [3]
  • Teams that prefer managed transaction-signing wallets over implementing and operating signer infrastructure themselves.[2]

Buying and deployment notes

Platforms: REST API, Web dashboard, Client SDKs[1], [2], [3]

Deployment: Vendor-hosted managed wallet and API service[1], [2], [3]

Important considerations
  • A managed wallet must be provisioned and funded with the target network's gas token before it can submit transactions.[1], [2]
  • Each callable endpoint must be configured for a specific contract method, network, contract address, accepted parameters, and default wallet before an agent can invoke it.[1]

Autonomy level

47%

Reasoning: 1Shot API is not an autonomous AI agent itself, but rather an on-chain automation infrastructure layer that enables and facilitates autonomous transaction execution. It provides autonomy capabilities through: (1) automated smart contract transaction execution via REST API with single POST calls, (2) non-custodial transaction processing with real-ti...
