Overview
icy.tools (now powered by QuickNode) is a GraphQL-based NFT API that provides data on NFT collections, wallet holdings, and historical transaction activity across major blockchains. It enables developers to query NFT metadata, floor prices, and ownership history with flexible GraphQL queries rather than fixed REST routes. Typical use cases include NFT portfolio dashboards, rarity checkers, and marketplace analytics tools.
Beginner Tip
Unlike typical REST APIs, icy.tools uses GraphQL — you send POST requests with a JSON body containing a "query" string, which gives you precise control over exactly which NFT data fields you receive.

const response = await fetch(url, {
headers: {

}
});
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data); What Can You Build?
