{"openapi":"3.1.0","info":{"title":"ADX & Trend-Strength Screener (Multi-Asset) API","version":"1.0.0","description":"Which markets are strongly trending and which are stuck going nowhere, computed live from Yahoo Finance (no key, nothing stored). The Average Directional Index is the definitive measure of trend STRENGTH (not direction): above 25 a market has a real trend worth riding, below 20 it is choppy and range-bound where trend systems get whipsawed. The companion +DI and -DI lines give the direction — +DI over -DI is an uptrend, the reverse a downtrend. For a cross-asset, cross-sector universe — equity indices and sectors, gold, oil, commodities, bonds and crypto — this computes each asset's 14-day ADX, +DI and -DI (Wilder's method), and classifies it as a strong uptrend, strong downtrend, developing trend or ranging. The screener endpoint returns the strong uptrends and downtrends across the board, ranked by ADX, plus the ranging list. The asset endpoint returns one market's directional-movement card. The universe endpoint lists what is covered. The cross-asset ADX / trend-strength screener cut — distinct from the bring-your-own-candle trend-indicator API and the moving-average, RSI, MACD, Bollinger and Donchian screeners. It separates the trending markets from the chop across every asset class at once.","contact":{"name":"PremiumApi","url":"https://www.oanor.com/by/premiumapi"}},"servers":[{"url":"https://api.oanor.com/adxscreener-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 strong up/down trends and ranging markets ranked by ADX","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 ADX / directional-movement 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":770,"rps_limit":2,"hard_limit":true},{"slug":"starter","name":"Starter","price_cents_month":1142,"monthly_call_quota":17200,"rps_limit":6,"hard_limit":true},{"slug":"pro","name":"Pro","price_cents_month":3420,"monthly_call_quota":89000,"rps_limit":16,"hard_limit":true},{"slug":"business","name":"Business","price_cents_month":7820,"monthly_call_quota":484000,"rps_limit":40,"hard_limit":true}],"x-oanor-marketplace-url":"https://www.oanor.com/api/adxscreener-api"}
