FAQ

What is Farcaster? Farcaster is a decentralized social protocol built on Ethereum. Users post "casts" (similar to tweets) that are stored on-chain. It is one of the leading Web3 social platforms, with an active user base of crypto-native creators and developers.

Do I need a Farcaster account or wallet? No, the scraper uses the public Warpcast API. No authentication or wallet is required.

What is an FID? FID (Farcaster ID) is the numeric identifier for a Farcaster user. You can use either a username or FID as input — the scraper automatically resolves usernames to their corresponding FID.

How many results can I get per run? Up to 10,000 results per run using the maxResults parameter. The scraper uses automatic cursor-based pagination to fetch all available casts.

Is scraping Farcaster legal?

Yes. This scraper only accesses publicly available data through the public Warpcast API. It does not bypass authentication or access private data. Farcaster is a decentralized protocol designed for open data access. Always check Warpcast's Terms of Service for restrictions on how you use the data.
