Launchbox SDK Documentation

Introduction

The Launchbox SDK provides a set of functions to interact with Farcaster channels, fetch user information, casts, and social capital metrics. This document describes how to use the various functions available in the SDK.

Installation

To install the Launchbox SDK, you need to include it in your project. Use npm or yarn to install the package:

npm add channels-lib

or using Yarn

yarn add channels-lib

Usage

Import the SDK and initialize with your API key:

import Launchbox from 'launchbox-sdk';

const launchbox = new Launchbox('your-api-key');

// Example: Fetch channels by user address
const ownerAddress = '0x459D7FB72ac3dFB0666227B30F25A424A5583E9c';
launchbox.getChannelsByUserAddress(ownerAddress)
  .then(channels => {
    console.log('Channels:', channels);
  })
  .catch(error => {
    console.error('Error fetching channels:', error.message);
  });

// Example: Calculate social capital score for a channel
const channelName = 'example_channel';
const tokenAddress = '0x57f1887a8bf19b14fc0df6fd9b2acc9af147ea85';
launchbox.getChannelSocialCapital(channelName, tokenAddress)
  .then(score => {
    console.log('Social capital score:', score);
  })
  .catch(error => {
    console.error('Error calculating social capital:', error.message);
  });
