与 Ankr 交互的压缩 JavaScript 库 高级 API。 。 。 .

两分钟后开始

1. 从npm安装软件包

# with npm
npm install @ankr.com/ankr.js

# with yarn
yarn add @ankr.com/ankr.js

2. 初始化提供者

注:要从2023年5月29日起免费使用高级API,您必须在平台注册.

把你的个人终点拿来 https://www.ankr.com/rpc/advanced-api (中文(简体) ) 并提供给 AnkrProvider 建筑师.

import { AnkrProvider } from '@ankr.com/ankr.js';

const provider = new AnkrProvider('YOUR_ENDPOINT');

3. 使用提供者并调用所支持的方法之一

await provider.getNFTsByOwner({
  blockchain: 'eth',
  walletAddress: '0x0E11A192d574b342C51be9e306694C41547185DD',
