#protocols

Live data on the fees users pay to DeFi protocols and the revenue those protocols actually keep — the "which protocols earn money" view, a different layer from Total Value Locked. TVL is what is deposited; fees are what users pay to use a protocol; revenue is the slice the protocol or its token-holders retain. Powered by the public DeFiLlama fees feed, no key, nothing stored. The overview endpoint returns the whole-DeFi fee (or revenue) total for the last 24 hours, 7 days and 30 days plus every protocol ranked by what it earns, with its category and chains. The protocol endpoint returns a single protocol's fee and revenue figures side by side across 24h / 7d / 30d / all-time (e.g. Aave, Uniswap, Lido). The chain endpoint returns the fee or revenue total and top-earning protocols for one blockchain (Ethereum, Solana, Base). Switch any list between gross fees and retained revenue with a single metric parameter. This is the fees-and-revenue cut of DeFi — distinct from the TVL, DEX-volume, exchange-ticker and coin-markets APIs in the catalogue.

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.

The IANA Uniform Resource Identifier (URI) Schemes registry as an API — all 413 registered schemes (http, https, mailto, tel, ftp, ssh, magnet, bitcoin, geo, did, …). Look up any scheme to get its description, registration status (Permanent, Provisional or Historical) and defining reference; search by name or description; or list all schemes filtered by status. Ideal for URL parsers and validators, link handlers, deep-linking, security allow-lists and developer tooling that needs to recognise or vet URI schemes.
