CryptoKeyhole

CryptoKeyhole is an independent crypto analytics site. This connector gives Claude read-only access to its public metrics for Bitcoin, Ethereum and a growing list of coins and tokens: on-chain series calculated from the Bitcoin, Ethereum, Litecoin, Dogecoin and Bitcoin Cash nodes we run ourselves, plus market data we collect. Ask things like "How many bitcoin blocks were mined each day this week?", "What is Ethereum's circulating supply today?" or "Which metrics do you have for Solana?" and Claude reads the answer from the data instead of guessing. Tools: get_assets_list, get_metrics_list, get_asset_metrics, get_metric_metadata, fetch_metric and fetch_bulk_metrics. Every metric comes with its definition, method, source and coverage. Values arrive as exact decimal strings, every observation states its finality (partial, provisional or final) and its source clock, and missing observations are reported as gaps, never as zero. The connector serves what CryptoKeyhole's Free plan includes, needs no account or key, and cannot change anything. A chart that needs a paid plan answers with the plan that includes it. Licence: charts and data shown in full without a paid plan, including the free API, are licensed CC BY 4.0 (credit "CryptoKeyhole" with a link to cryptokeyhole.com). Paid-plan data and raw exchange data are not covered. Details: https://cryptokeyhole.com/methodology/#licence-title
