API reference
Get started with our APIs for Users, Casts, Social Graphs and Feeds
Read
Everything else you need to start building:
Farcaster 101
Users
Every user on Farcaster is represented by a permanent FID, the user’s numerical identifier.
All user profile data for this FID (username, display name, bio, etc) are stored on the Farcaster protocol and mapped to this FID.
Casts
Users can broadcast information to the protocol in units of information called casts. It’s somewhat similar to a post on X.
Each cast has a unique hash.
User relationships
Users can follow each other to see casts from them. This creates a social graph for each user on Farcaster.
From the blog
Check out our index for feature releases, customer spotlights and more.
Explore Farcaster network
Unlike centralized social networks, Farcaster's open protocol gives you access to full network data, so you can build with confidence.
