OneShot

Infrastructure for autonomous AI agents to execute real-world commercial transactions: email, payments, e-commerce, research, and data enrichment with native x402 payments.

Quick Start

npm install @oneshot-agent/sdk

With CDP Wallet (Recommended — no private keys):

import { OneShot } from '@oneshot-agent/sdk';

// Reads CDP_API_KEY_ID, CDP_API_KEY_SECRET, CDP_WALLET_SECRET from env
const agent = await OneShot.create({ cdp: true });

// Send an email
await agent.email({
  to: 'recipient@example.com',
  subject: 'Hello from my agent',
  body: 'This email was sent autonomously.'
});

With Raw Private Key:

import { OneShot } from '@oneshot-agent/sdk';

const agent = new OneShot({
  privateKey: process.env.ONESHOT_WALLET_PRIVATE_KEY
});

Authentication

OneShot uses x402 payments (USDC on Base). Two wallet options:

Option A: Coinbase CDP Wallet (Recommended)

Server-side wallet managed by Coinbase — no private keys in your config. Signing happens in Coinbase's secure enclave (TEE).

export CDP_API_KEY_ID="your-api-key-id"
export CDP_API_KEY_SECRET="your-api-key-secret"
export CDP_WALLET_SECRET="your-wallet-secret"

const agent = await OneShot.create({ cdp: true });

Get credentials at Coinbase Developer Platform. The SDK auto-creates a wallet on first use. Optional: npm install @coinbase/cdp-sdk

Option B: Raw Private Key (Advanced)

Direct wallet control for agents managing their own keys:

export ONESHOT_WALLET_PRIVATE_KEY="0xYourPrivateKey"

const agent = new OneShot({ privateKey: process.env.ONESHOT_WALLET_PRIVATE_KEY });

Custom Wallet Provider

Bring your own signing implementation:

const agent = await OneShot.create({
  walletProvider: {
    address: '0x...',
    signTypedData: async (domain, types, value) => signature
  }
});

Test Mode: SDK runs in test mode by default (Base Sepolia testnet). Set ONESHOT_TEST_MODE=false for production.

MCP Server

Use OneShot tools in Claude Desktop, Cursor, OpenClaw, or Claude Code:

npm install -g @oneshot-agent/mcp-server

With CDP Wallet (Recommended):

{
  "mcpServers": {
    "oneshot": {
      "command": "npx",
      "args": ["-y", "@oneshot-agent/mcp-server"],
      "env": {
        "CDP_API_KEY_ID": "your-api-key-id",
        "CDP_API_KEY_SECRET": "your-api-key-secret",
        "CDP_WALLET_SECRET": "your-wallet-secret"
      }
    }
  }
}

With Raw Private Key:

{
  "mcpServers": {
    "oneshot": {
      "command": "npx",
      "args": ["-y", "@oneshot-agent/mcp-server"],
      "env": {
        "ONESHOT_WALLET_PRIVATE_KEY": "0xYourPrivateKey"
      }
    }
  }
}

Funding Your Agent

Add USDC to your agent's wallet on Base network:

1. Get wallet address: console.log(agent.address)
2. Send USDC (Base) to the address
3. Or use https://oneshotagent.com to fund

Test mode uses Base Sepolia testnet (free test USDC).

Error Handling

import { OneShot, ContentBlockedError, InsufficientBalanceError } from '@oneshot-agent/sdk';

try {
  const result = await agent.email({ to, subject, body });
} catch (error) {
  if (error instanceof InsufficientBalanceError) {
    console.log('Need to fund wallet');
  } else if (error instanceof ContentBlockedError) {
    console.log('Content policy violation');
  }
}
