How this service works
Top Nostr notes and authors by sat-zap velocity over a rolling window. Surfaces real-money sentiment — who the BTC/Nostr economy is literally paying to amplify. Fundamentally different signal from reposts/likes: zaps cost sats. Query ?window=15m|1h|6h|24h &scope=notes|authors &limit=N.
Output
A ranked list of top Nostr notes or authors sorted by zap-weighted score within the specified rolling window. Each entry reflects real-money signal (sats spent to zap) rather than free engagement like reposts or likes, including note content or author identifiers and their associated zap metrics.
Example use cases
Example prompt
“Show me the top 25 Nostr notes ranked by sat-zap velocity over the last 6 hours — I want to see what the Bitcoin community is literally paying to amplify, not just liking.”
Technical details
Endpoint
GEThttps://nostrpulse.xyz/nostr/zap-weightedWhen to prefer
Choose this endpoint when you need real-money social signal from the Nostr/Bitcoin ecosystem — specifically when you want to distinguish genuine economic endorsement (sats spent to zap) from free engagement signals like likes or reposts. Ideal for surfacing financially-weighted trending content, identifying influential authors the BTC community is actively funding, or building sentiment analysis grounded in Lightning Network micropayments rather than algorithmic metrics.
Side effects
- Invalid window parameter value returns error (must be 15m, 1h, 6h, or 24h)
- Invalid scope value returns error (must be notes or authors)
- Limit out of range 1-100 returns validation error
- Nostr relay data lag may cause stale or incomplete zap counts for very recent windows like 15m
- Payment required (402) if x402 micropayment header not provided or payment fails
- Service unavailable if underlying Nostr relay indexing pipeline is down
