Insight: Token Lookup And Collection Metadata

Toomas Oosalu

Insight adds two new endpoints - one to lookup a token based on symbols and one to retrieve an NFT collection's metadata.

Search for tokens by their symbol across 6000+ tokens.

Symbols are not unique nor strictly curated however, so be careful with how you use them!

To fetch all tokens with symbol ETH on Ethereum and B3

const lookupTokens = async (symbol: string) => {
  try {
    const response = await fetch(
      `https://insight.thirdweb.com/v1/tokens/lookup?symbol=${symbol}&chain=1`,
      {
        headers: {
          "x-client-id": <THIRDWEB_CLIENT_ID>,
        },
      },
    );
    const res = await response.json();
    return res.data;
  } catch (error) {
    console.error("Error:", error);
  }
};
await lookupTokens("ETH")

Get metadata about an NFT collection.

By including a include_stats=true query param, you can also get the following statistics about a collection:

• owner_count - Amount of distinct addresses that hold the NFTs
• mint_count - Amount of NFT tokens that have been minted
• token_count - Amount of distinct token IDs that currently exist
• total_quantity - Amount of tokens that currently exist

const getCollectionMetadata = async (contractAddress: string) => {
  try {
    const response = await fetch(
      `https://1.insight.thirdweb.com/v1/nfts/collection/${contractAddress}?include_stats=true`,
      {
        headers: {
          "x-client-id": <THIRDWEB_CLIENT_ID>,
        },
      },
    );
    const res = await response.json();
    return res.data;
  } catch (error) {
    console.error("Error:", error);
  }
};
