XRP LedgerのパブリックAPI
XRP Ledgerとは
XRPレジャーはBitcoinやEthereumなどと同じ分散型のパブリックブロックチェーンです。PoWやPoSとは異なる独自のコンセンサスアルゴリズムが用いられています。
EVMによるスマートコントラクトは搭載しておらず、スマートトランザクタ(プロトコルネイティブで提供されている機能)を拡張することで進化し続けています。
XRP Lederの情報はレジャーオブジェクトやレジャーエントリなどと呼ばれ、レジャー全体で一意となるキーで識別されています。
データの取得
XRP Ledgerからデータを取得する方法の最も基礎的なものとしてPublic APIが提供されています。
これはXRPLのサーバアプリケーションであるrippledから提供されているものであり、XRP Ledgerネットワークの情報を他の第三者に依存せずに取得できます。
特徴
XRPLのパブリックAPIではXRPLのデータを一意なキーで取得したり、特定のリストなどを取得できます。
XRP Ledgerサーバと直接通信を行うため信頼性が高いデータとなっています。
パブリックAPIの種類
アカウント
アカウントの基本情報やトークン情報など、アカウントに関する情報を取得するAPIです。
account_channels
アカウントが作成した、または宛先として含まれるペイメントチャネルを取得します。

コード例
xrpl.jsを使ってパブリックAPIを利用してみましょう。
account_infoとledger_entryを利用し、2つの方法でアカウントの情報を取得してみます。。
account_info
アカウント情報をより詳細に取得します。フラグなどがよりヒューマンリーダブルな形式で取得できます。
import { Client } from "xrpl"
const main = async () => {

await client.connect()

ページング
パブリックノードから大きなサイズのリスト情報を取得する場合、一度に取得可能なサイズに制限があります。そのため、ページングを利用してリストを取得する必要があります。
リクエスト
import { AccountTxTransaction, Client, Transaction } from "xrpl"
const main = async () => {
const client = new Client('wss://xrpl.ws')
await client.connect()
let transaction: AccountTxTransaction[] = []

まとめ
XRPLではXRP Ledgerサーバと直接通信を行い、レジャーのデータを取得することが可能です。
取得可能なデータは多岐にわたり、アカウント情報やトランザクション情報、オーダーブック情報などを取得することができます。
トランザクションの送信とこのデータ取得を組み合わせることで、XRP Ledgerを利用した様々なアプリケーションを作成することができます。
興味を持たれた方はXRP Ledger開発者のDiscordチャンネルへ是非お越しください！
日本語チャンネルもありますので、英語ができなくても大丈夫です！
また、XRPL JapanのDiscordサーバもありますので、こちらもぜひご参加ください！
