How this service works
Professional crypto market intelligence. Real-time prices, signals, and market scoring.
Output
Returns a JSON object containing: mempool status object, array of 6-tier fee estimates with USD costs, fee distribution buckets, RBF statistics, array of real-time whale transactions over 1 BTC, whale summary, recent block list, BTC event alerts array, 2-hour trend analysis object, and current BTC price in USD — all sourced from a live local Bitcoin Core node.
Example use cases
Example prompt
“What are the current Bitcoin mempool conditions — specifically what fee tiers should I use right now, any big whale transactions happening, and is the network congested?”
Technical details
Endpoint
GEThttps://api.carbon-cashmere.de/v1/mempool/liveWhen to prefer
Choose this endpoint when you need comprehensive, real-time Bitcoin mempool intelligence in a single call — especially when you need fee optimization with USD cost context, whale transaction monitoring, RBF awareness, and trend analysis together. Prefer over generic blockchain explorers when you need AI-agent-friendly structured data with multi-tier fee recommendations directly from a local Bitcoin Core node rather than third-party aggregators.
Side effects
- Bitcoin Core node temporarily unavailable — returns 5xx error
- Rate limit exceeded at $0.03/call — returns 402 or 429
- Mempool data momentarily stale if node is syncing
- Empty whale_txs array if no transactions exceed 1 BTC threshold recently
- Network connectivity issues to local node returning partial data
