Chainworks API
Welcome to the Chainworks API documentation. Build powerful DeFi applications with our unified WebSocket API.
What is Chainworks?
Chainworks provides a WebSocket-based DeFi API that enables developers and institutions to easily access trading, token analysis, and other DeFi functionality across multiple blockchains.
Supported Chains
| Chain | Identifier | Type | Native Token |
|---|---|---|---|
| Ethereum | eth | EVM | ETH |
| Base | base | EVM | ETH |
| BNB Chain | bsc | EVM | BNB |
| Solana | sol | SVM | SOL |
Core Features
Token Trading
Execute swaps across multiple DEXes with optimal routing. Get quotes, build transactions, and send them with MEV protection.
Price Quotes
Real-time price quotes with slippage calculation, price impact analysis, and liquidity information.
Token Reports
Comprehensive token analysis including:
- Liquidity depth
- Buy/sell taxes
- Transfer limits
- Holder restrictions
- Market data
Multi-Chain Transfers
Build and send native currency and token transfers across all supported chains.
Quick Example
typescript
import { io } from "socket.io-client";
const socket = io(CHAINWORKS_API_URL, {
transports: ["websocket"],
auth: { token: CHAINWORKS_API_AUTH_TOKEN },
});
socket.on("connect", () => {
console.log("Connected to Chainworks API");
// Get a buy quote
socket.emit("/evm/buy/quote", {
chain: "eth",
token: "0x6982508145454Ce325dDbE47a25d4ec3d2311933",
swapMode: "ExactIn",
amountIn: "1000000000000000000",
wallet: "0xYourWallet",
});
});
socket.on("/evm/buy/quote", (response) => {
if (response.success) {
console.log("Price:", response.result.price);
}

Frequently Asked Questions
What is Chainworks?
- Chainworks is a unified WebSocket API for building DeFi applications. One integration gives you trading, quotes, wallet data, and token info across Solana, Ethereum, Base, and BNB Chain.
Which blockchains does Chainworks support?
- Solana is the primary supported chain. Ethereum, Base, and BNB Chain are supported in beta. All chains share the same WebSocket API surface so you can write one integration.
How do I authenticate with the Chainworks API?
- Authentication is token-based. You pass your API URL and auth token to the Socket.IO client on connect; see /docs/authentication for the exact handshake.
What transport does the API use?
- The Chainworks API is delivered over a single WebSocket connection using Socket.IO. You emit requests and listen for responses on the same event name — no REST calls and no polling.
Can I try the API without writing code?
- Yes. The /playground page is an interactive tester where you can pick an endpoint, fill in parameters, connect with your credentials, and inspect the live response.
Where can I see the full machine-readable docs?
- Every docs page has a .md twin (for example, /docs/quickstart.md), and /llms-full.txt contains all documentation concatenated for LLM ingestion. /llms.txt is a compact index.
