{"openapi":"3.1.0","info":{"title":"Cross-Asset Correlation Matrix API","version":"1.0.0","description":"How the major asset classes move together — a live correlation matrix across stocks, bonds, gold, oil, crypto and the dollar (no key, nothing stored). Correlation is the single most important input to diversification and risk: two assets with a correlation near 1 are effectively the same bet, while a low or negative correlation is genuine diversification. Where a crypto-correlation API stays inside crypto and an FX-correlation API stays inside currencies, this spans the whole multi-asset book at once — US and international equities, Treasuries and credit, gold, silver, oil and broad commodities, Bitcoin and Ether, the dollar and real estate — so an allocator can see in one call whether bonds are still hedging stocks, whether gold is decoupled and whether crypto is trading as a risk asset. The matrix endpoint returns the full pairwise return-correlation matrix over a chosen window, with the most- and least-correlated pairs. The asset endpoint returns one asset's correlation to every other, ranked, so you see its best diversifiers at a glance. The assets endpoint lists what is covered. The cross-asset / multi-asset correlation surface — distinct from the crypto-only correlation API, the FX-only currency-correlation API and the bring-your-own-series CAPM, risk-metrics and portfolio-optimiser calculators.","contact":{"name":"PremiumApi","url":"https://www.oanor.com/by/premiumapi"}},"servers":[{"url":"https://api.oanor.com/crossassetcorrelation-api","description":"oanor gateway"}],"tags":[{"name":"Matrix"},{"name":"Asset"},{"name":"Assets"},{"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/matrix":{"get":{"operationId":"get_v1_matrix","tags":["Matrix"],"summary":"Full pairwise cross-asset correlation matrix with most/least correlated pairs","description":"","parameters":[{"name":"window","in":"query","required":false,"description":"Lookback in days (20-365)","schema":{"type":"string"},"example":"90"}],"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/asset":{"get":{"operationId":"get_v1_asset","tags":["Asset"],"summary":"One asset correlation to all others, ranked, with best diversifiers","description":"","parameters":[{"name":"asset","in":"query","required":true,"description":"Asset key (see /v1/assets)","schema":{"type":"string"},"example":"gold"},{"name":"window","in":"query","required":false,"description":"Lookback in days (20-365)","schema":{"type":"string"},"example":"90"}],"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/assets":{"get":{"operationId":"get_v1_assets","tags":["Assets"],"summary":"Supported cross-asset instruments","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":"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":700,"rps_limit":2,"hard_limit":true},{"slug":"starter","name":"Starter","price_cents_month":1132,"monthly_call_quota":18000,"rps_limit":6,"hard_limit":true},{"slug":"pro","name":"Pro","price_cents_month":3422,"monthly_call_quota":90000,"rps_limit":16,"hard_limit":true},{"slug":"business","name":"Business","price_cents_month":7920,"monthly_call_quota":480000,"rps_limit":40,"hard_limit":true}],"x-oanor-marketplace-url":"https://www.oanor.com/api/crossassetcorrelation-api"}
