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

Initialization

To use the SDK, you need to initialize it with your API key and environment.

import Launchbox from 'launchbox';

const launchbox = new Launchbox('your-api-key', 'prod'); // Use 'dev' for the development environment

Functions

1. getChannelsByUserAddress - Fetches channels associated with a user's address.

/**
 * Fetches channels associated with a user's address.
 * @param {`0x${string}`} owner - The Ethereum address of the user in hexadecimal format.
 * @returns {Promise<ChannelsByUserResponse['data']>} A promise that resolves to the data containing the channels associated with the user.
 * @throws Will throw an error if the query fails.
 */

public async getChannelsByUserAddress(owner: `0x${string}`): Promise<ChannelsByUserResponse['data']>

2. getCasts -Fetches casts from a specified channel.

/**
 * Fetches casts from a specified channel.
 * @param {string} channelUrl - The URL of the channel to fetch casts from.
 * @returns {Promise<Cast[]>} An array of casts from the channel.
 * @throws Will throw an error if the query fails.
 */
public async getCasts(channelUrl: string): Promise<Cast[]>

3. getNumberOfWeeklyCasts - Fetches the number of casts in a channel made within the last week.

/**
 * Fetches the number of casts in a channel made within the last week.
 * @param {string} channelUrl - The URL of the channel to fetch casts from.
 * @returns {Promise<number>} The number of casts made in the last week.
 * @throws Will throw an error if the query fails.
 */
public async getNumberOfWeeklyCasts(channelUrl: string): Promise<number>

4. getParticipantTokenBalances - Fetches the token balances for participants in a given channel.

/**
 * Fetches the token balances for participants in a given channel.
 * @param {ParticipantTokenBalancesParams} params - The parameters for the query.
 * @returns {Promise<Participant[]>} The participants with their token balances.
 * @throws Will throw an error if the query fails.
 */
public async getParticipantTokenBalances(params: ParticipantTokenBalancesParams): Promise<Participant[]>

5. getChannelSocialCapital - Fetches the social capital of a channel.

/**
 * Fetches the social capital of a channel.
 * @param {string} channelName - The name of the channel.
 * @param {string} [chain='base'] - The blockchain to query (default is 'base').
 * @param {`0x${string}`} token - The token address in hexadecimal format.
 * @param {number} [limit=50] - The maximum number of participants to fetch.
 * @returns {Promise<number>} The social capital score of the channel.
 * @throws Will throw an error if the query fails.
 */
public async getChannelSocialCapital(channelName: string, chain: string = "base", token: `0x${string}`, limit: number = 50): Promise<number>
