Endpoint
POSThttps://x402-farcaster-social-signal-production.up.railway.app/token/social-signalWhen to prefer
Use this endpoint when you need to quantify social momentum of a specific Base ERC-20 token using Farcaster engagement data. Ideal for crypto research agents evaluating token hype, traders assessing social sentiment before a trade, or dashboards ranking Base tokens by community activity. Prefer over generic social listening tools when the target chain is Base and the social layer is Farcaster specifically.
Side effects
- Unknown token symbol — no matching Base token found, returns empty or error
- Invalid contract address format — returns validation error
- No Farcaster activity found for the token in the lookback window — returns score of 0 with empty topCasts
- hoursBack value too large — may time out or return partial data
- Payment failure — x402 payment not accepted, returns 402
