{"openapi":"3.1.0","info":{"title":"Sky (MakerDAO) Savings Rate & Protocol API","version":"1.0.0","description":"Live protocol stats from Sky, the decentralized stablecoin protocol formerly known as MakerDAO and the issuer of the USDS and DAI stablecoins — no key, nothing stored. This is the Sky-protocol view: the Sky Savings Rate (SSR) and DAI Savings Rate (DSR), the value locked in savings, the SKY staking yield and the overall ecosystem size, distinct from the generic DeFi-TVL, yields and lending APIs in the catalogue. The overview endpoint returns the latest ecosystem snapshot — the Sky Savings Rate APY, the savings TVL, the SKY staking APY, the farm APY, the total reward TVL, the whole-ecosystem TVL, the wallet count and the number of savings depositors. The savings endpoint returns the current savings rates: the live SSR and DSR and the dollar value deposited in each. The history endpoint returns the savings-rate timeline — per-day SSR, DSR and deposited totals — so you can chart how the on-chain risk-free rate has moved. Build DeFi yield dashboards, stablecoin-savings widgets, rate-comparison tools and treasury bots on top of the dominant decentralized stablecoin protocol. SSR and DSR are the on-chain savings benchmarks for USDS and DAI; rates are returned as percentages.","contact":{"name":"PremiumApi","url":"https://www.oanor.com/by/premiumapi"}},"servers":[{"url":"https://api.oanor.com/sky-api","description":"oanor gateway"}],"tags":[{"name":"Overview"},{"name":"Savings"},{"name":"History"},{"name":"Meta"}],"components":{"securitySchemes":{"oanorKey":{"type":"apiKey","in":"header","name":"x-oanor-key","description":"Get your key at https://www.oanor.com/developer/keys"}}},"security":[{"oanorKey":[]}],"paths":{"/v1/overview":{"get":{"operationId":"get_v1_overview","tags":["Overview"],"summary":"Latest Sky ecosystem snapshot","description":"","parameters":[],"security":[{"oanorKey":[]}],"responses":{"200":{"description":"OK"},"401":{"description":"Missing or invalid x-oanor-key header"},"402":{"description":"Active subscription required"},"429":{"description":"Rate-limit or monthly quota reached"},"502":{"description":"Upstream did not respond"}}}},"/v1/savings":{"get":{"operationId":"get_v1_savings","tags":["Savings"],"summary":"Current SSR and DSR savings rates","description":"","parameters":[],"security":[{"oanorKey":[]}],"responses":{"200":{"description":"OK"},"401":{"description":"Missing or invalid x-oanor-key header"},"402":{"description":"Active subscription required"},"429":{"description":"Rate-limit or monthly quota reached"},"502":{"description":"Upstream did not respond"}}}},"/v1/history":{"get":{"operationId":"get_v1_history","tags":["History"],"summary":"Daily savings-rate timeline","description":"","parameters":[{"name":"limit","in":"query","required":false,"description":"Days back (default 30, max 365)","schema":{"type":"string"},"example":"30"}],"security":[{"oanorKey":[]}],"responses":{"200":{"description":"OK"},"401":{"description":"Missing or invalid x-oanor-key header"},"402":{"description":"Active subscription required"},"429":{"description":"Rate-limit or monthly quota reached"},"502":{"description":"Upstream did not respond"}}}},"/v1/meta":{"get":{"operationId":"get_v1_meta","tags":["Meta"],"summary":"Service metadata","description":"","parameters":[],"security":[{"oanorKey":[]}],"responses":{"200":{"description":"OK"},"401":{"description":"Missing or invalid x-oanor-key header"},"402":{"description":"Active subscription required"},"429":{"description":"Rate-limit or monthly quota reached"},"502":{"description":"Upstream did not respond"}}}}},"x-oanor-pricing":[{"slug":"free","name":"Free","price_cents_month":0,"monthly_call_quota":12500,"rps_limit":3,"hard_limit":true},{"slug":"starter","name":"Starter","price_cents_month":880,"monthly_call_quota":185000,"rps_limit":10,"hard_limit":true},{"slug":"pro","name":"Pro","price_cents_month":2620,"monthly_call_quota":790000,"rps_limit":28,"hard_limit":true},{"slug":"scale","name":"Scale","price_cents_month":5920,"monthly_call_quota":2850000,"rps_limit":60,"hard_limit":true}],"x-oanor-marketplace-url":"https://www.oanor.com/api/sky-api"}
