How this service works
Deep per-block Bitcoin extract. Returns miner-pool attribution, witness/taproot adoption %, Ordinals inscription count, OP_RETURN byte volume, fee percentiles (10/25/50/75/90), UTXO delta, segwit %, total output BTC, block weight.
Output
A rich JSON object for the requested block height including: miner pool name/attribution, witness and Taproot adoption percentage, count of Ordinals inscriptions, OP_RETURN byte volume, fee percentiles at p10/p25/p50/p75/p90, UTXO delta (created minus spent), SegWit transaction percentage, total BTC output value, and block weight in weight units — all sourced from a live own-node ZMQ rawblock parser.
Example use cases
Monitor miner pool shifts weekly
“Give me the block analytics for the last 10 Bitcoin blocks and show me which pools mined them, their Taproot adoption rates, and how the fee percentiles have moved — I want to spot any big mining shifts happening right now.”
Track Ordinals inscription trends
“Pull the deep analytics for blocks 850000 through 850010 and get me the Ordinals inscription count for each one, plus the SegWit and Taproot adoption percentages. I'm trying to see if inscription activity is picking up and whether newer transactions are adopting Taproot.”
Analyze fee market behavior daily
“Fetch the per-block data for the last 144 blocks and give me a summary of how fee percentiles — the 10th, 50th, and 90th — have moved across those blocks. Also include OP_RETURN byte volumes and UTXO deltas so I can understand what's driving fee pressure right now.”
Technical details
Endpoint
GEThttps://api.carbon-cashmere.de/v1/btc-derivatives/blocks/:heightWhen to prefer
Choose this endpoint when you need granular, per-block Bitcoin analytics far beyond what standard block explorers expose — specifically miner pool attribution, Ordinals inscription counts, Taproot/SegWit adoption metrics, detailed fee percentile distributions, and OP_RETURN volumes for a precise block height. Ideal for blockchain researchers, indexer builders, and explorer developers who need structured machine-readable block-level data from an own-node source rather than a third-party aggregator.
Side effects
- Block height not yet mined — returns 404 or not-found error
- Block height out of valid range — returns 400 bad request
- Node temporarily out of sync — may return stale or missing data
- Invalid non-integer height parameter — returns validation error
- Rate limit or payment failure — returns 402 or 429 error
