NFT Collections API

degraded 3,973 Subscribers

Live NFT collection market data — no key, nothing cached. For any collection it returns the numbers that matter: the floor price in both the chain's native currency and US dollars, the 24-hour floor change, the collection market cap, the 24-hour trading volume and its change, the number of unique owners and the total supply, plus the contract address, the chain and the project's links — Pudgy Penguins floors around 4.3 ETH with thousands of unique owners and a market cap in the tens of millions. The list endpoint pages through the collections that are tracked, and the search endpoint finds a collection by name. It spans every chain NFTs are indexed on — Ethereum, Solana, Polygon and more. This is the collection-floor-and-volume layer for any NFT marketplace, wallet, portfolio or analytics app. Live, served from the public CoinGecko feed, nothing stored. Distinct from token-price and single-chain APIs — this is NFT collection floor prices, market caps and volumes. 4 endpoints.

Crypto Trending API

What the crypto market is searching for right now, served live from the public CoinGecko trending feed with no key. This is hype and attention data — distinct from market-cap rankings, exchange tickers and DeFi feeds — surfacing the coins, NFT collections and categories with the biggest spike in search interest over the last 24 hours. The coins endpoint returns the trending coins ranked by search popularity, each with its live USD price, 24-hour change, market cap, 24-hour volume, market-cap rank and BTC price. The nfts endpoint returns the trending NFT collections with floor price (native and display), 24-hour floor change and 24-hour volume. The categories endpoint returns the trending narratives and sectors with market cap, volume and 24-hour change. Trending means ranked by CoinGecko search popularity, so rank 1 is the single most-searched asset of the moment — exactly the signal traders, bots and dashboards use to catch a move early. Read live from CoinGecko, nothing stored beyond a short protective cache. Ideal for crypto dashboards, trading bots, sentiment and hype trackers, and discovery feeds. Live, no key. 3 trending endpoints. For full price history use an OHLC or exchange API.

Magic Eden API

Live Solana NFT-marketplace data from Magic Eden, the largest NFT marketplace on Solana — a marketplace order-book and trade-feed layer, not a floor-price aggregator: live collection market stats (floor price in SOL, listed count, 24h average sale price, all-time volume), the live order book of tokens on sale (SOL ask price, seller, token mint, rarity rank) and the live trade feed (buys, listings, bids, delistings with price, buyer, seller, on-chain signature and time).
