How this service works
Farcaster social-graph slice for a fid or username: the following list with a count, the follower floor with a count, and a sample of mutual connections. Counts for large accounts are a floor with a capped flag. Social-graph context for reputation and network-analysis agents.
Output
Returns a structured object containing: the list of accounts the user follows with a count, the list of followers with a floor count (and a capped flag if the account is large), and a sample of mutual connections between the queried user and others. Large accounts return floor counts with a capped indicator rather than exact totals.
Example use cases
Example prompt

Technical details
Endpoint
GEThttps://api.agentstools.dev/farcaster/graphWhen to prefer
Use this endpoint when you need Farcaster-specific social graph data including follower/following counts and mutual connections for reputation scoring, network analysis, or identity enrichment. Prefer this over generic social APIs when the target platform is Farcaster and you need both counts and relationship context in a single call.
Side effects
- Neither fid nor username provided — returns error requiring at least one identifier
- FID below minimum value of 1 — schema validation error
- Username not found on Farcaster — 404 or empty result
- Payment not included or insufficient — 402 Payment Required
- Large account with capped follower count returns approximate floor, not exact total
