{"openapi":"3.1.0","info":{"title":"Bithumb Exchange API","version":"1.0.0","description":"Live spot market data from Bithumb, South Korea's major crypto exchange, served straight from its public order books — no key on the data, nothing cached, nothing stored. Look up any market for its last price, 24h open/high/low, 24h change and base/quote volume; rank every market for a payment currency (Korean won KRW, or BTC) by 24h turnover; list the tradable coins; or pull live order-book depth with the running spread. Markets are addressed COIN_PAYMENT (BTC_KRW, ETH_BTC). This is the Bithumb venue specifically — a distinct Korean-won price feed, ideal for tracking the \"kimchi premium\" and KRW price discovery, separate from the USD/USDT-quoted exchange APIs in the catalogue.","contact":{"name":"PremiumApi","url":"https://www.oanor.com/by/premiumapi"}},"servers":[{"url":"https://api.oanor.com/bithumb-api","description":"oanor gateway"}],"tags":[{"name":"Ticker"},{"name":"Tickers"},{"name":"Markets"},{"name":"Book"},{"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/ticker":{"get":{"operationId":"get_v1_ticker","tags":["Ticker"],"summary":"Ticker for one market","description":"","parameters":[{"name":"market","in":"query","required":false,"description":"Market as BTC_KRW","schema":{"type":"string"},"example":"BTC_KRW"},{"name":"coin","in":"query","required":false,"description":"Coin (with payment=)","schema":{"type":"string"},"example":"ETH"},{"name":"payment","in":"query","required":false,"description":"Payment currency KRW or BTC","schema":{"type":"string"},"example":"KRW"}],"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/tickers":{"get":{"operationId":"get_v1_tickers","tags":["Tickers"],"summary":"All markets for a payment currency ranked by 24h turnover","description":"","parameters":[{"name":"payment","in":"query","required":false,"description":"Payment currency KRW or BTC","schema":{"type":"string"},"example":"KRW"},{"name":"limit","in":"query","required":false,"description":"Max results (1-400)","schema":{"type":"string"},"example":"50"}],"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/markets":{"get":{"operationId":"get_v1_markets","tags":["Markets"],"summary":"Tradable coins for a payment currency","description":"","parameters":[{"name":"payment","in":"query","required":false,"description":"Payment currency KRW or BTC","schema":{"type":"string"},"example":"KRW"}],"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/book":{"get":{"operationId":"get_v1_book","tags":["Book"],"summary":"Live order-book depth with running spread","description":"","parameters":[{"name":"market","in":"query","required":false,"description":"Market as BTC_KRW","schema":{"type":"string"},"example":"BTC_KRW"},{"name":"limit","in":"query","required":false,"description":"Depth per side (1-30)","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/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":19000,"rps_limit":3,"hard_limit":true},{"slug":"starter","name":"Starter","price_cents_month":915,"monthly_call_quota":270000,"rps_limit":10,"hard_limit":true},{"slug":"growth","name":"Growth","price_cents_month":2685,"monthly_call_quota":1220000,"rps_limit":25,"hard_limit":true},{"slug":"scale","name":"Scale","price_cents_month":6260,"monthly_call_quota":4400000,"rps_limit":50,"hard_limit":true}],"x-oanor-marketplace-url":"https://www.oanor.com/api/bithumb-api"}
