# Crypto Fees API > 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. ## Authentication All requests require your oanor API key in the `x-oanor-key` header.
