{"openapi":"3.1.0","info":{"title":"CCI Screener (Multi-Asset) API","version":"1.0.0","description":"Which markets are stretched to an overbought or oversold extreme on the Commodity Channel Index, computed live from Yahoo Finance (no key, nothing stored). The CCI measures how far price has run from its statistical average relative to normal volatility: above +100 a market is in a strong up-move (and, when it unwinds, overbought), below -100 a strong down-move (or oversold), and the swing through zero frames trend and reversal trades. For a cross-asset, cross-sector universe — equity indices and sectors, gold, oil, commodities, bonds and crypto — this computes each asset's 20-period CCI from its typical price (high+low+close over three) and tags it overbought, bullish, bearish or oversold, then ranks the whole board. The screener endpoint returns the overbought (>+100) and oversold (<-100) markets right now. The asset endpoint returns one market's CCI card. The universe endpoint lists what is covered. The cross-asset CCI / extension screener cut — distinct from the bring-your-own-candle oscillator API, the RSI screener (a different oscillator), the OBV/volume and Bollinger screeners. It finds the over-extended markets across every asset class at once.","contact":{"name":"PremiumApi","url":"https://www.oanor.com/by/premiumapi"}},"servers":[{"url":"https://api.oanor.com/cci-api","description":"oanor gateway"}],"tags":[{"name":"Screener"},{"name":"Asset"},{"name":"Universe"},{"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/screener":{"get":{"operationId":"get_v1_screener","tags":["Screener"],"summary":"Cross-asset board with overbought/oversold CCI extremes, ranked","description":"","parameters":[{"name":"class","in":"query","required":false,"description":"Filter by class: equities, sector, commodities, bonds, crypto","schema":{"type":"string"},"example":"sector"}],"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 market CCI card","description":"","parameters":[{"name":"asset","in":"query","required":true,"description":"Asset key (see /v1/universe)","schema":{"type":"string"},"example":"sp500"}],"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/universe":{"get":{"operationId":"get_v1_universe","tags":["Universe"],"summary":"Supported 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":820,"rps_limit":2,"hard_limit":true},{"slug":"starter","name":"Starter","price_cents_month":1066,"monthly_call_quota":17600,"rps_limit":6,"hard_limit":true},{"slug":"pro","name":"Pro","price_cents_month":3360,"monthly_call_quota":90500,"rps_limit":16,"hard_limit":true},{"slug":"business","name":"Business","price_cents_month":7640,"monthly_call_quota":496000,"rps_limit":40,"hard_limit":true}],"x-oanor-marketplace-url":"https://www.oanor.com/api/cci-api"}
