Carbon Cashmere BTC On-Chain Pulse Analytics
x402
Carbon Cashmere BTC On-Chain Pulse Analytics is a paid API for AI agents from api.carbon-cashmere.de, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-15).
Returns a comprehensive snapshot of Bitcoin network health including mempool pressure z-score, hashrate momentum, fee regime, UTXO velocity, SegWit adoption, and difficulty adjustment prediction from a live Bitcoin Core full node.

How this service works
Professional crypto market intelligence. Real-time prices, signals, and market scoring.
Output
A JSON object with seven sections: mempool (regime, size_mb, tx_count, pressure z-score over 30d, total_fees_btc), fees (regime, next_block and six_block sat/vb estimates, 90d percentile rank), hashrate (current EH/s, 7d/30d momentum, trend label), difficulty_adjustment (blocks_until, predicted_delta_pct, hash_ribbon_status), utxo (count, 24h velocity, total_supply_btc), adoption (segwit_pct, taproot_pct, 30d slopes), and _meta (timestamp, source, cache_hit, disclaimer).
Example use cases
Example prompt
“Can you pull the latest Bitcoin on-chain pulse — I want to see current mempool pressure, fee regime, hashrate trend, SegWit adoption, and how far we are from the next difficulty adjustment?”
Technical details
Endpoint
GEThttps://api.carbon-cashmere.de/v1/onchain-pulse/btcWhen to prefer
Use this endpoint when you need a multi-dimensional snapshot of Bitcoin network health from a single call — combining fee market, mempool congestion, miner activity, and adoption metrics together. Prefer this over generic block explorer APIs when you need statistically enriched signals like 30-day z-scores, momentum ratios, and trend classifications rather than raw block data. Best for research agents, crypto dashboards, and automated monitoring workflows that need actionable on-chain context about Bitcoin network conditions.
Side effects
- Node sync lag may produce stale cache_hit=true data if Bitcoin Core is behind chain tip
- mempool metrics may be near-zero during low-activity periods, making z-scores less meaningful
- taproot_pct and hash_ribbon_status may return null if the node lacks sufficient historical data
- HTTP 402 Payment Required if x402 USDC payment header is missing or invalid
- HTTP 503 if the Postgres cache or Bitcoin Core node is temporarily unavailable
