快速开始

TypeScript
// Replace YOUR_API_KEY with your Helius API key
const url = `https://mainnet.helius-rpc.com/?api-key=YOUR_API_KEY`;

async function searchAssets(params) {
  const body = {
    jsonrpc: "2.0",
    id: "search-assets-example",
    method: "searchAssets",
    params,
  };
  const res = await fetch(url, {
    method: "POST",
    headers: { "Content-Type": "application/json" },
    body: JSON.stringify(body),
  });
  if (!res.ok) {
    throw new Error(`${res.status} ${res.statusText}`);
  }
  const { result } = await res.json();
  return result;
}

// Example: fetch first 50 compressed NFTs in a wallet
searchAssets({
  ownerAddress: "86xCnPeV69n6t3DnyGvkKobf9FdN2H9oiVDdaMpo2MMY",
  tokenType: "compressedNft",
  limit: 50,
}).then(console.log);
page 参数从 1 开始。为了实现极快的无限滚动，请使用游标分页（before/after）。

​
核心概念

​
1. 选择 tokenType

​
tokenType
string
required
一个必需的字符串，指定您希望在响应中获得哪种资产。
可接受的值：fungible、nonFungible、regularNft、compressedNft、all。
tokenType您得到的内容典型用例
fungible仅限 SPL 和 Token-22 代币钱包余额、代币门控
nonFungible所有 NFT（压缩和常规）投资组合概览
regularNft传统和 pNFT（未压缩）市场列表
compressedNft仅限 cNFT超低成本大规模铸造
all所有内容（代币和NFT）全面发现

​
2. 分页和排序

Solana 钱包可以拥有数千个资产——高效的分页很重要。
  • Page / Limit – 经典分页（page 从 1 开始）。适用于静态视图。
  • Cursor – 传递上一个响应中的 before 或 after 值，以实现快速的无限滚动。
"sortBy": {
  "sortBy": "created",      // created | recent_action | updated | none
  "sortDirection": "desc"   // asc | desc
}
有关 page/limit 和基于游标的策略的完整代码示例，请访问专门的分页指南。

​
3. 显示选项 (options)

这些标志添加元数据；它们从不改变返回的资产。
标志效果
showNativeBalance包含钱包的 SOL 余额
showCollectionMetadata添加集合级别的 JSON 数据
showGrandTotal返回总匹配计数（较慢）
showInscription附加铭文和 SPL-20 信息（实验性）
"options": {
  "showNativeBalance": true,
  "showCollectionMetadata": true,
  "showGrandTotal": true,
  "showInscription": true
}
