FAQ

How do I collect NFT marketplace data?

Use marketplace APIs (OpenSea, Magic Eden) for structured listing and sales data, on-chain RPC queries for transaction data, and web scraping with proxies for UI-specific data not available through APIs.

For API-based collection, proxies are not needed. For web scraping marketplace UIs or collecting social media sentiment data, residential proxies are recommended with 72-85% success rates.

What is the best NFT data API?

Reservoir Protocol offers the best aggregated marketplace data. OpenSea API v2 has the most comprehensive single-marketplace data. Alchemy NFT API provides the best on-chain NFT queries.

How do I track NFT whale wallets?

Use Etherscan API or direct RPC subscriptions to monitor specific wallet addresses. Nansen and Arkham Intelligence provide pre-identified whale wallet labels and tracking dashboards.
