比特币 K 线行情客户端 —— 免费、无需密钥的公开接口,按顺序尝试多个源,首个成功即返回。
|
||
|
||
源(均为公开 REST,无鉴权):
|
||
1. OKX GET /api/v5/market/candles?instId=BTC-USDT&bar=<1H|1D> —— 主源,本地直连可达、数据最新
|
||
2. Coinbase GET /products/BTC-USD/candles?granularity=<3600|86400> —— 备源(USD 计价,与 USDT 数值几乎一致)
|
||
3. Huobi GET /market/history/kline?period=<60min|1day>&symbol=btcusdt —— 备源
|
||
(Binance 在本地区返回 restricted location,不列入。)
|
||
|
||
周期用统一代号 bar:"1H"(时 K)/ "1D"(日 K),由 BARS 映射到各源的写法。
|
||
统一输出:按时间**升序**的 list[dict],每根 {"ts": epoch 秒, "o", "h", "l", "c"}(float),最后一根为当前未收盘的那根。
|
||
任何源失败抛异常并尝试下一个;全部失败抛 RuntimeError,由 data 层决定沿用缓存或占位。
