#fees

Live crypto protocol fee and revenue data across the whole ecosystem as an API, streamed from the DefiLlama fees feed. For thousands of protocols and chains: the fees paid by users over the last 24 hours, 7 days and 30 days, the all-time total, and the day/week/month change. Rank the protocols actually earning the most — a fundamental "who makes money" view of crypto — drill into any single protocol, read the market-wide fee total, or search. Built for crypto, fundamental-analysis and dashboard apps. Live, no key. Distinct from TVL, yield, stablecoin-supply and price APIs — this is the fee and revenue surface.

Live Bitcoin on-chain and mempool data as an API, built on the open mempool.space dataset — a different layer from market-price feeds. Get recommended transaction fees (sat/vB) for fast, half-hour, hour and economy confirmation, the current mempool state with its fee histogram, the most recent blocks and full block detail by height or hash (size, weight, transaction count, mining pool, reward and fees). Look up any Bitcoin address for its confirmed and unconfirmed balance and transaction counts, or any transaction by id for its inputs, outputs, fee and confirmation status. Track the difficulty-adjustment countdown, mining-pool hashrate share, the network hashrate over time and the current BTC price. Real on-chain data, no key needed upstream. Ideal for wallets, block explorers, fee estimators, mining dashboards and crypto analytics.
