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 JSON object containing: the list of accounts the target user follows, a follower count (expressed as a floor for large accounts with a 'capped' boolean flag), and a sample of mutual connections between the queried account and others. Large accounts with very high follower counts return a floor value with capped=true rather than an exact count.
Example use cases
Reputation check for Farcaster user
“I want to assess the reputation of the Farcaster user with FID 3 — can you get me their follower count, who they follow, and a sample of mutual connections?”
Influencer network analysis
“Look up the Farcaster social graph for the username 'dwr.eth' — I need their following list and follower floor to understand their reach on the network.”
Mutual connections discovery
“Can you find mutual connections between my Farcaster account and username 'jessepollak'? Pull the social graph slice so I can see overlapping connections.”
Technical details
Endpoint
GEThttps://payai.agentstools.dev/farcaster/graphWhen to prefer
Choose this endpoint when you need Farcaster-specific social graph data — following lists, follower counts, and mutual connections — for reputation scoring, network analysis, or onboarding flows in a decentralized social context. Prefer it over generic social API wrappers when you need structured, cost-efficient Farcaster graph slices without building your own Farcaster indexer integration. It is especially useful when you need mutual connection sampling, which generic follower-count APIs do not provide.
Side effects
- Neither fid nor username provided — returns error requiring at least one identifier
- Invalid FID (non-positive integer) — validation error
- Unknown username or FID not found on Farcaster — 404 or empty result
- Payment not provided or insufficient — 402 Payment Required (x402 protocol)
- Rate limiting or upstream Farcaster API unavailability — 429 or 503 response
