SideShift.ai API Client

A TypeScript client library for the SideShift.ai API.

Installation

npm install sideshift-node-sdk

Quick Start

1. Setup Environment Variables

Add the following variables to your .env file:

# Required: Your x-sideshift-secret (needed for private endpoints)
SIDESHIFT_PRIVATE_KEY=your_private_key_here

# Required: Your affiliate/account ID (used as affiliateId)
SIDESHIFT_AFFILIATE_ID=your_affiliate_id_here

# Optional: API base URL (default is https://sideshift.ai/api/v2)
SIDESHIFT_BASE_URL=https://sideshift.ai/api/v2

# Optional: Global default rate limit (default is 60 req/min)
SIDESHIFT_RATE_LIMIT=60

# Optional: Enable verbose logging
SIDESHIFT_VERBOSE=false

How to get your credentials:

1. Visit sideshift.ai
2. Create a shift on the site or visit the Account page — this will automatically create an account
3. Copy your:
   • Private Key (x-sideshift-secret)
   • Account ID (affiliateId)

---

2. Initialize the Client

import { SideShiftClient } from '../SideShiftClient';
import { loadSideShiftConfig } from '../utils/loadSideShiftConfig';

const config = loadSideShiftConfig();
const sideShiftClient = new SideShiftClient(config);

---

Here are some examples of HTTP API calls:

// Get coins
const coins = await sideShiftClient.coins.getCoins();
console.log(coins.data);

// Create a fixed shift
const body = {
    settleAddress: 'settle-address',
    settleMemo: 'settle-memo',
    quoteId: 'quote-id',
    refundAddress: 'refund-address',
};
const fixedShift = await sideShiftClient.order.postFixedRateShift(body);
console.log(fixedShift.data);

// Get account information
const account = await sideShiftClient.account.getAccount();
console.log(account.data);

All HTTP requests, responses, and parameters are defined as types within the library, enabling strict type checking. Type definitions strictly follow the official API specification.

// Example with type annotations
const quoteBody: QuoteBody = {
    depositCoin: 'BTC',
    settleCoin: 'ETH',
    depositAmount: '0.01',
    settleAmount: null,
};

const response: ApiResponse<Quote> = await sideShiftAPI.orders.postRequestQuote(quoteBody);

HTTP API Response Format

All HTTP API responses follow the ApiResponse interface:

export interface ApiResponse<T> {
    success: boolean;
    data: T | null;
    error?: string;
    status?: number;
}

Success Response Example

{
  success: true,
  data: {
    id: 'account-id',
    lifetimeStakingRewards: '0',
    unstaking: '0',
    staked: '0',
    available: '0',
    totalBalance: '0'
  },
  status: 200
}

Error Response Example

See https://docs.sideshift.ai/troubleshoot-errors for an overview of all errors.

{
  success: false,
  data: null,
  error: 'GET /account failed: 401 Unauthorized - Account required. Add x-sideshift-secret header',
  status: 401
}

3. Authentication

All authentication processes are handled inside the SideShiftHttpClient when using private endpoints. You only need to provide your Private Key and Account Id in your .env file.

4. Permissions

SideShift.ai restricts access from certain countries. To comply, use the /v2/permissions endpoint with the user's IP address to check if usage is allowed. If the userIp is omitted, the IP address of the request origin will be used instead.

The following endpoints require the user's IP via the x-user-ip header:

• GET /permissions
• POST /quotes
• POST /shifts/fixed
• POST /shifts/variable
• POST /checkouts

// Create a fixed shift with user ip
const userIp = 1.23.45.678
const body = {
  settleAddress: "settle-address",
  settleMemo: "settle-memo",
  quoteId: "quote-id",
  refundAddress: "refund-address",
};
const fixedShift = await sideShiftClient.order.postFixedRateShift(body, userIp);
console.log(fixedShift.data);

Features

• TypeScript Support: Complete type definitions for all API requests and responses
• REST API Client: Access to all SideShift.ai endpoints (public and private)
