Overview - ChainStream

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)
});

from chainstream import ChainStreamClient
from chainstream.stream import Resolution

client = ChainStreamClient(access_token='YOUR_ACCESS_TOKEN')

# REST API call
token = await client.token.get_metadata('sol', 'TOKEN_ADDRESS')

# WebSocket subscription
await client.stream.subscribe_token_candles(
    chain='sol',
    token_address='TOKEN_ADDRESS',
    resolution=Resolution.S1,
    callback=lambda data: print(data)
)

import chainstream "github.com/chainstream-io/chainstream-go-sdk"

client, _ := chainstream.NewChainStreamClient(accessToken, &chainstream.ChainStreamClientOptions{})

// REST API call
resp, _ := client.Token.GetToken(ctx, "sol", "TOKEN_ADDRESS")

// WebSocket subscription
client.Stream.SubscribeTokenCandles("sol", "TOKEN_ADDRESS", token.N1s, func(data stream.TokenCandle) {
    fmt.Println(data)
}, "")

use chainstream_sdk::{ChainStreamClient, stream::{Resolution, TokenCandle}};

let client = ChainStreamClient::new("YOUR_ACCESS_TOKEN", None);

// WebSocket subscription
client.stream.subscribe_token_candles(
    "sol",
    "TOKEN_ADDRESS",
    Resolution::X1s,
    |candle: TokenCandle| {
        println!("{:?}", candle);
    },
    None,
).await?;

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
