{"openapi":"3.1.0","info":{"title":"Golden Cross / Death Cross Screener API","version":"1.0.0","description":"Which markets just flipped trend on the most-watched signal in technical analysis — the 50-day vs 200-day moving-average cross — computed live from Yahoo Finance (no key, nothing stored). A golden cross, the 50-day average crossing up through the 200-day, is the classic confirmation of a new uptrend, and a death cross the opposite; funds and headlines move on them. For a cross-asset, cross-sector universe — equity indices and sectors, gold, oil, commodities, bonds and crypto — this computes each asset's 50- and 200-day moving averages, whether it is in a golden-cross (bullish) or death-cross (bearish) regime, how many days since the last cross, and how far price sits above or below each average. The screener endpoint returns the whole board with the markets that have crossed most recently — the fresh golden and death crosses — and the bullish/bearish tally. The asset endpoint returns one market's moving-average card. The universe endpoint lists what is covered. The moving-average-crossover / golden-cross screener cut — distinct from the bring-your-own-candle technical-indicator APIs, the market-breadth API (which aggregates the share above a single moving average) and the FX-only signals API.","contact":{"name":"PremiumApi","url":"https://www.oanor.com/by/premiumapi"}},"servers":[{"url":"https://api.oanor.com/goldencross-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 golden/death-cross regimes, fresh crosses and tally","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 moving-average 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":730,"rps_limit":2,"hard_limit":true},{"slug":"starter","name":"Starter","price_cents_month":1066,"monthly_call_quota":16800,"rps_limit":6,"hard_limit":true},{"slug":"pro","name":"Pro","price_cents_month":3222,"monthly_call_quota":89000,"rps_limit":16,"hard_limit":true},{"slug":"business","name":"Business","price_cents_month":7360,"monthly_call_quota":482000,"rps_limit":40,"hard_limit":true}],"x-oanor-marketplace-url":"https://www.oanor.com/api/goldencross-api"}
