{"openapi":"3.1.0","info":{"title":"Crypto Derivatives API","version":"1.0.0","description":"A cross-exchange aggregator of cryptocurrency perpetual-futures and derivatives markets — the funding rates, open interest and volume that drive leveraged crypto trading, pulled together across every listed derivatives exchange (Binance, Bybit, OKX, Hyperliquid, MEXC and dozens more). The perps endpoint ranks the largest perpetual markets by open interest with their price, funding rate, open interest and 24h volume. The funding endpoint compares the funding rate of one asset (e.g. BTC, ETH, SOL) across every exchange that lists it, with the average — so you can spot funding dislocations and basis trades at a glance. The exchanges endpoint ranks derivatives venues by open interest with their perpetual and futures pair counts. The overview endpoint aggregates total open interest, total 24h volume and the perpetual-pair count across the whole derivatives market. The meta endpoint documents the API. Live aggregated data, lightly cached; funding rates are percentages, open interest in USD per market and BTC for venue totals. Live. 5 endpoints. This aggregates derivatives across all exchanges; for a single exchange's raw order book use that exchange's API.","contact":{"name":"PremiumApi","url":"https://www.oanor.com/by/premiumapi"}},"servers":[{"url":"https://api.oanor.com/cryptoderivatives-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/exchanges":{"get":{"operationId":"get_v1_exchanges","tags":["Derivatives"],"summary":"Derivatives exchanges ranked by open interest","description":"","parameters":[{"name":"limit","in":"query","required":false,"description":"Number of exchanges (default 25, max 50)","schema":{"type":"string"},"example":"25"}],"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/funding":{"get":{"operationId":"get_v1_funding","tags":["Derivatives"],"summary":"Funding rates for an asset across all exchanges","description":"","parameters":[{"name":"base","in":"query","required":false,"description":"Asset symbol (default BTC), e.g. BTC, ETH, SOL","schema":{"type":"string"},"example":"BTC"}],"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/overview":{"get":{"operationId":"get_v1_overview","tags":["Derivatives"],"summary":"Aggregate derivatives market: total OI, volume, pairs","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/perps":{"get":{"operationId":"get_v1_perps","tags":["Derivatives"],"summary":"Top perpetual markets ranked by open interest","description":"","parameters":[{"name":"limit","in":"query","required":false,"description":"Number of markets (default 30, max 100)","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":"API 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":250,"rps_limit":2,"hard_limit":true},{"slug":"basic","name":"Basic","price_cents_month":1480,"monthly_call_quota":17500,"rps_limit":5,"hard_limit":true},{"slug":"pro","name":"Pro","price_cents_month":3720,"monthly_call_quota":92000,"rps_limit":20,"hard_limit":true},{"slug":"mega","name":"Mega","price_cents_month":8240,"monthly_call_quota":410000,"rps_limit":55,"hard_limit":true}],"x-oanor-marketplace-url":"https://www.oanor.com/api/cryptoderivatives-api"}
