{"openapi":"3.1.0","info":{"title":"Crypto Donchian Breakout Screener API","version":"1.0.0","description":"Which coins are breaking out of their recent trading range, computed live from Binance candles — no key, nothing stored. The Donchian channel is the highest high and lowest low of the last N periods; a price above the upper band is a classic trend-following breakout (the original turtle-trading signal) and a price below the lower band a breakdown. The breakout endpoint returns, for one pair, the N-day Donchian upper and lower bands, the current price, where it sits in the channel (0% at the low, 100% at the high), the distance to each band and a status — new_high, new_low, near_high, near_low or inside. The screener endpoint scans a basket of coins and surfaces the ones currently breaking to new highs (momentum-long candidates) and to new lows (breakdowns), ranked by how decisively they have cleared the band. The symbols endpoint lists tradable pairs. This is the range-breakout / Donchian-screener cut for crypto — distinct from the generic indicator calculators (which you feed your own data), the volume-profile, the seasonality and the order-flow APIs in the catalogue. Bands use the prior completed candles, so a breakout is a genuine move beyond the established range. Pairs are Binance symbols (BTCUSDT) or a coin=BTC&quote=USDT form; lookback is 5-200 days.","contact":{"name":"PremiumApi","url":"https://www.oanor.com/by/premiumapi"}},"servers":[{"url":"https://api.oanor.com/cryptobreakout-api","description":"oanor gateway"}],"tags":[{"name":"Breakout"},{"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/breakout":{"get":{"operationId":"get_v1_breakout","tags":["Breakout"],"summary":"One pair's Donchian channel & breakout status","description":"","parameters":[{"name":"symbol","in":"query","required":true,"description":"Binance pair","schema":{"type":"string"},"example":"BTCUSDT"},{"name":"lookback","in":"query","required":false,"description":"Channel length in days (5-200, default 20)","schema":{"type":"string"},"example":"20"}],"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/screener":{"get":{"operationId":"get_v1_screener","tags":["Breakout"],"summary":"Scan a basket for breakouts & breakdowns","description":"","parameters":[{"name":"coins","in":"query","required":false,"description":"Comma list of coins (default liquid majors)","schema":{"type":"string"},"example":"BTC,ETH,SOL,DOGE,XRP"},{"name":"lookback","in":"query","required":false,"description":"Channel length in days (5-200, default 20)","schema":{"type":"string"},"example":"20"}],"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/symbols":{"get":{"operationId":"get_v1_symbols","tags":["Breakout"],"summary":"Tradable Binance pairs","description":"","parameters":[{"name":"quote","in":"query","required":false,"description":"Filter by quote asset","schema":{"type":"string"},"example":"USDT"}],"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":"Spec","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":400,"rps_limit":2,"hard_limit":true},{"slug":"starter","name":"Starter","price_cents_month":1144,"monthly_call_quota":12200,"rps_limit":6,"hard_limit":true},{"slug":"pro","name":"Pro","price_cents_month":3488,"monthly_call_quota":71000,"rps_limit":16,"hard_limit":true},{"slug":"business","name":"Business","price_cents_month":7960,"monthly_call_quota":365000,"rps_limit":40,"hard_limit":true}],"x-oanor-marketplace-url":"https://www.oanor.com/api/cryptobreakout-api"}
