How this service works
Deterministic Farcaster social-reputation score from zero to one hundred for a fid, username or address. Combines account age, verified wallets, a primary address, username presence, follower floor and cast activity into a score, a band and per-dimension reasons. Anti-sybil and provenance signal for crypto agents. Reputation indicators, not a guarantee.
Output
A JSON object containing a numeric reputation score from 0 to 100, a categorical band (e.g. low/medium/high), and per-dimension reason strings covering account age, verified wallets, primary address presence, username presence, follower floor, and cast activity. Designed as an anti-sybil and provenance signal for crypto agents.
Example use cases
Example prompt
“Can you pull the Farcaster reputation score for the username 'vitalik' — I want to know their score, band, and why they got scored that way before I let them interact with my agent?”
Technical details
Endpoint
GEThttps://api.agentstools.dev/farcaster/reputationWhen to prefer
Use this endpoint when you need a deterministic, multi-dimensional reputation score for a Farcaster identity — especially in crypto agent workflows requiring anti-sybil checks, provenance validation, or trust gating. Prefer it over generic social metrics when you specifically need Farcaster-native signals (FID, casts, verified wallets) combined into a single normalized score. Also appropriate when you have an Ethereum address and want to resolve its Farcaster reputation indirectly.
Side effects
- No FID/username/address provided — returns 400 or error requiring at least one query parameter
- Unknown or non-existent Farcaster username — returns error or zero-score result
- Invalid Ethereum address format — returns validation error
- FID below minimum (< 1) — rejected by schema validation
- Payment not completed (x402) — returns 402 Payment Required
- Rate limit exceeded — returns 429 Too Many Requests
