NFT Floor Price Tracker (ETH, SOL, BTC, Polygon)

What does NFT Floor Price Tracker do?

NFT Floor Price Tracker delivers live NFT floor price data — in both USD and native token — plus 24h, 7d, and 30d percentage changes, market cap, and 24h trading volume for curated collections across Ethereum, Solana, Bitcoin (Ordinals/Runes), Polygon, Arbitrum, and Base. It wraps the CoinGecko free public NFT endpoint so you get instant NFT collection analytics for any tracked collection with no API key required.

Built-in defaults cover 20+ blue-chip collections (CryptoPunks, BAYC, Mad Lads, NodeMonkes, and more). Pass your own collectionIds list to track niche collections or custom watchlists. Optional Telegram alerts notify you when a floor drops beyond a threshold you set.

Why use NFT Floor Price Tracker?

1. Trade alerts and floor drop monitoring — Get a Telegram notification the moment a collection you hold drops more than 10% in 24 hours, enabling faster exit or accumulation decisions.
2. Custom NFT portfolio index — Aggregate floor prices and volume for your exact watchlist into a single dataset run on a schedule, replacing manual browser checking across multiple marketplaces.
3. Market sentiment tracking — Aggregate 24h volume across blue-chip collections to detect when NFT activity is rotating, heating up, or cooling off across the whole market.
4. Cross-chain NFT comparison — Compare ETH NFTs vs. Solana NFTs vs. Bitcoin Ordinals/Runes at a glance using a unified USD-denominated view.
5. OpenSea floor price API alternative — OpenSea and Magic Eden APIs are gated or rate-limited. This actor provides equivalent floor and volume data via the CoinGecko free public endpoint — no key, no waitlist.

FAQ

Is this a real OpenSea floor price API replacement? This actor wraps the CoinGecko free public NFT endpoint, which aggregates floor data from major marketplaces including OpenSea, Magic Eden, and others. It covers the most widely tracked collections. For very niche or newly launched collections not yet on CoinGecko, coverage may be limited.

How do I find a collection's CoinGecko slug? Go to coingecko.com/en/nft, find the collection, and copy the last segment of the URL. For example, https://www.coingecko.com/en/nft/cryptopunks → slug is cryptopunks.

Does the NFT collection analytics data update in real time? CoinGecko's free public endpoint updates periodically (typically every few minutes). For intraday floor price monitoring, schedule this actor to run every 15–30 minutes.

Disclaimer: NFT floor prices are highly volatile and may not reflect the actual price at which a specific item can be sold. Data is sourced from CoinGecko's public NFT API and may lag real-time marketplace prices. This actor is for informational and research purposes only — not financial advice.
