NBBO：全市场最优买卖价
单件 CS2 饰品在所有已接入市场上的 NBBO（全市场最优买卖价），附新鲜度元数据、基点价差与置信度评分。可按 id（规范 id）或 market_hash_name 查询，可选用 markets CSV 收窄范围。价格为整数美分。
NBBO 回答一个问题：同时看*所有*市场，现在买入的最优价是多少、卖出的最优价是多少？bestAsk 是全场最低在售价（并标明来源市场）；bestBid 是全场最高求购价；两者之间的差就是 spreadBps，以基点计。
并非每件饰品都有双边市场。当没有任何市场存在求购单时，bestBid 与 spreadBps 返回 null——这是正常情况，不是错误（见 null 与部分数据）。confidence（0 到 1）综合了参与市场数量、数据新鲜度与跨市场一致性，可用来对单薄或过期的读数做降权。
locked（求购价 == 在售价）与 crossed（扣除卖方平台预估佣金后的求购价 > 在售价）标记跨市场报价倒挂的罕见时刻，通常是一边的报价先于另一边刷新而过期。若你的策略依赖价差，请据此过滤。
默认情况下 bestBid 只统计可现金变现的市场（Steam 钱包余额与以物易物额度类平台被排除），因此默认的跨市场求购价是真正能变现的价格。传入 markets CSV 则改为逐字采信每个被请求平台的求购价。/v1/pricing 采用同样的默认规则，因此除非传入 markets，两者一致。
spreadBps 超过 10000 基点（±100%）时会被置为 null 以剔除垃圾求购价。本接口保留交叉（负）价差并同时给出 crossed 标志；定价类读取在交叉盘口时则返回 null。若要的是可实际执行的价差而非标价价差，请读取可为 null 的 executionAdjusted 块：它在扣除手续费并按可执行性折价后对双边重新定价，并带有自己的 spreadBps 与 executableConfidence。
想要完整的按市场拆解而不只是最优两边？用 /v1/pricing/:marketHashName。想看盘口之下的挂单深度？用 /v1/nbbo/depth。
按游戏区分的版本：GET /v2/nbbo 通过必填参数 game=cs2|rust 同时服务两款游戏，响应结构、认证与配额均相同。见游戏：CS2 与 Rust。
参数
id 二选一（都缺失返回 400）。market_hash_name 二选一（都缺失返回 400）。csfloat,buff163。传入后还会覆盖默认的"仅现金变现市场"的 bestBid 过滤规则：所有被请求平台的求购价将被逐字采信。响应字段
嵌套与共享结构链接到 API 对象 参考页。
错误
market_hash_name 与 id 均未提供。Authorization 头、认证方案不支持，或密钥未知、未激活、已过期、已吊销。使用此端点的指南（英文）
