{"openapi":"3.1.0","info":{"title":"Crypto Derivatives Exchanges API","version":"1.0.0","description":"Live ranking and directory of crypto derivatives venues — the platforms that run perpetual and futures markets — served from the public CoinGecko feed with no key and nothing cached. This is a venue-level view of the derivatives market, distinct from spot-exchange directories, per-contract open-interest feeds and single-exchange tickers: it ranks the derivatives platforms themselves. The exchanges endpoint returns the venues ranked by open interest (or by 24-hour volume), each with its open interest in BTC, 24-hour derivatives volume in BTC, the number of perpetual and futures pairs it lists, its country and the year it was established — so one call tells you who the biggest derivatives venues are and how concentrated open interest is. The exchange endpoint returns a single venue's full profile by id. The list endpoint returns every derivatives-exchange id and name for lookup and autocomplete. Everything is read live from CoinGecko on each request, nothing stored beyond a short protective cache. Ideal for derivatives dashboards, open-interest and market-structure analytics, venue comparison and trading tools. Live, no key. 3 endpoints. For per-contract funding and open-interest history use a derivatives or open-interest API.","contact":{"name":"PremiumApi","url":"https://www.oanor.com/by/premiumapi"}},"servers":[{"url":"https://api.oanor.com/derivativesexchanges-api","description":"oanor gateway"}],"tags":[{"name":"Derivatives"},{"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/exchange":{"get":{"operationId":"get_v1_exchange","tags":["Derivatives"],"summary":"One venue full profile","description":"","parameters":[{"name":"id","in":"query","required":true,"description":"Derivatives exchange id","schema":{"type":"string"},"example":"binance_futures"}],"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/exchanges":{"get":{"operationId":"get_v1_exchanges","tags":["Derivatives"],"summary":"Derivatives venues ranked by open interest or volume","description":"","parameters":[{"name":"order","in":"query","required":false,"description":"open_interest (default), volume or name","schema":{"type":"string"},"example":"open_interest"},{"name":"limit","in":"query","required":false,"description":"Max venues (default 50)","schema":{"type":"string"},"example":"50"}],"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/list":{"get":{"operationId":"get_v1_list","tags":["Derivatives"],"summary":"All derivatives-exchange ids and names","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/meta":{"get":{"operationId":"get_v1_meta","tags":["Meta"],"summary":"Spec","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":5500,"rps_limit":2,"hard_limit":true},{"slug":"starter","name":"Starter","price_cents_month":810,"monthly_call_quota":97000,"rps_limit":6,"hard_limit":true},{"slug":"pro","name":"Pro","price_cents_month":2340,"monthly_call_quota":510000,"rps_limit":18,"hard_limit":true},{"slug":"business","name":"Business","price_cents_month":5500,"monthly_call_quota":3150000,"rps_limit":45,"hard_limit":true}],"x-oanor-marketplace-url":"https://www.oanor.com/api/derivativesexchanges-api"}
