How this service works
Professional crypto market intelligence. Real-time prices, signals, and market scoring.
Output
Returns a JSON object containing: count of RBF-flagged whale transactions, confirmation rate of those transactions, BTC value distribution across size buckets, fee-rate premium percentage that RBF users pay versus non-RBF transactions, and current mempool fullrbf policy state. Data is sourced from a proprietary ZMQ stream tracking whale transactions.
Example use cases
Example prompt
“Pull the latest RBF-pulse data for Bitcoin whale transactions — I want to see how many large txs are flagged for replace-by-fee, what the fee-rate premium is over non-RBF transactions, and whether fullrbf policy is active in the mempool right now.”
Technical details
Endpoint
GEThttps://api.carbon-cashmere.de/v1/bitcoin/rbf-pulseWhen to prefer
Use this endpoint when you need specialized RBF analytics specifically scoped to whale (large-value) Bitcoin transactions, with fee-rate premium comparison and mempool fullrbf policy state. Prefer this over generic mempool explorers when the research question is specifically about replace-by-fee behavior, fee flexibility costs, or large-transaction RBF adoption rates.
Side effects
- ZMQ stream unavailable — may return 503 or stale data if internal node connection drops
- No whale transactions in recent window — could return zeroes or empty distributions
- Rate limiting at $0.08/call — x402 payment required, failure to attach valid payment returns 402
- Temporary mempool snapshot lag may cause slight staleness in fullrbf policy field
- Network timeouts if Bitcoin node is syncing or behind chain tip
