Power Features

Everything you need to ship.

Stop wrestling with RPCs, contract ABIs, transaction retries, and hunting for the right contract addresses. 1Shot API provides a unified developer and service layer for all your onchain products and projects with prompt-driven development.

Server Wallets

Programmatically provision wallets for high-throughput transaction relaying or agentic payments. Built in low balance alerts, transaction monitoring, retries and gas optimization.

Account Abstraction

1Shot API supports EIP-7702 transactions and has native support for MetaMask Delegation Framework. Build features that enable users and agents to safely transact even when they are not online.

x402 Support

Using 1Shot API's x402 facilitator, you can quickly launch your own pay-per-request API and accept payments in any x402-compatible token on any of our supported networks.
