Live long-term (about 10-year) government bond interest rates for around 44 countries, side by side, served from the OECD's official statistics in a single live call. The long-term government bond yield is the benchmark cost of money for an economy, and this puts the whole developed world on one screen — the United States, Germany, the United Kingdom, Japan, Canada, Australia, Brazil, Switzerland, Mexico, Colombia and dozens more — each with its latest published rate and the month it covers. The yields endpoint returns every country ranked by yield together with its spread over the German Bund, the euro-area safe-asset benchmark: in mid-2026 Colombia near 13.2%, Mexico 9.5% and Brazil 9.1% sit at the top while Switzerland near 0.5% sits at the bottom, with the US around 4.5% and the German Bund around 3.0%. The country endpoint returns one country's long-term yield with two years of recent monthly history. The spreads endpoint ranks every country by its yield spread over a chosen benchmark — Germany or the United States — the risk-and-rate-differential picture fixed-income and macro desks watch. This is the international-rates comparison layer for any fixed-income, forex, macro or research app. Live from the OECD, nothing stored. Distinct from single-country central-bank and yield-curve APIs — this is the cross-country sovereign-yield comparison across the developed world. Monthly OECD series; 4 endpoints. No key, no cache.

Live DeFi yield-farming APYs across the whole decentralised-finance ecosystem as an API, streamed from the DefiLlama yields feed. For thousands of liquidity pools across every chain and protocol: the current APY split into base and reward, the pool's TVL, its chain, project and token symbol, whether it is a stablecoin pool and its impermanent-loss risk. Rank the top yields with a sensible TVL floor (so dust-pool noise is filtered out), drill into any single protocol or chain, filter to stablecoin pools, or search. Built for DeFi, yield-aggregator and dashboard apps. Distinct from TVL and price APIs — this is the live yield surface. Note: very high APYs are reward-driven and transient; use a TVL floor, the stablecoin filter, or sort by TVL for durable yields.
