Official SDKs
ChainStream provides official SDKs in multiple languages, wrapping common API operations for a better development experience.
TypeScript
For Node.js and browser applications
Python
For data analysis and backend services
Go
For high-performance backend services
Rust
For systems programming and performance-critical applications
SDK Features
All SDKs provide:
- REST API Client: Call all ChainStream data APIs
- WebSocket Client: Subscribe to real-time data streams
- Auto Authentication: Automatic token management
- Type Safety: Full type definitions (TypeScript, Go, Rust)
Installation
TypeScript
Python
Go
Rust
npm install @chainstream-io/sdk
pip install chainstream-sdk
go get github.com/chainstream-io/chainstream-go-sdk
# Add to Cargo.toml
[dependencies]
chainstream-sdk = "0.1"
Quick Comparison
TypeScript
Python
Go
Rust
import { ChainStreamClient } from '@chainstream-io/sdk';
const client = new ChainStreamClient('YOUR_ACCESS_TOKEN');
// REST API call
const token = await client.token.getToken('sol', 'TOKEN_ADDRESS');
// WebSocket subscription
client.stream.subscribeTokenCandles({
chain: 'sol',
tokenAddress: 'TOKEN_ADDRESS',
resolution: Resolution['1s'],
callback: (data) => console.log(data)
});

SDK vs Direct API
| Feature | SDK | Direct API |
|---|
| Type Safety | Yes (TS/Go/Rust) | No |
| Auth Management | Automatic | Manual |
| Error Handling | Wrapped | Raw HTTP errors |
| WebSocket | Built-in | Manual implementation |
| Code Volume | Less | More |
| Flexibility | Medium | Full |
