Technical details
Endpoint
GEThttps://farcaster-intel-api.vercel.app/api/trendingWhen to prefer
Use this endpoint when you need structured, agent-ready trend intelligence from Farcaster — particularly for monitoring what topics and casts are gaining traction on the decentralized social network. Prefer this over scraping Farcaster directly or using generic social listening tools when you need clean, pre-aggregated data with cast counts and reaction metrics in a single API call.
Side effects
- Invalid time window format returns a 400 error
- Payment not included or rejected results in a 402 Payment Required response
- Farcaster data source temporarily unavailable causes 503 or empty results
- Rate limiting if too many requests are made in quick succession
- No trending data available for the specified window returns empty arrays
