为什么使用 HM Revenue & Customs 官方汇率？
市场汇率实时波动，但United Kingdom及其他地区的税务申报、报关、审计和法定会计通常要求使用 HM Revenue & Customs 在特定日期发布的官方汇率 — 一个固定、可引用、发布后不再变化的数字。本 API 提供的正是这些官方汇率表，每个响应都带有银行自己的发布日期（rate_date）；周末和节假日返回最近的发布日期 — 这正是合规规则要求适用的汇率。
银行未直接公布的货币对由其汇率表推算（倒数或经 GBP 的交叉汇率），并明确标记 "derived": true — 银行公布的数字与计算得出的数字绝不混淆。
端点
GET /api/v1/central-bank/hmrc/latest— 最新汇率表或单一货币对（所有套餐）GET /api/v1/central-bank/hmrc/{YYYY-MM-DD}— 任意日期的汇率表（付费套餐）GET /api/v1/central-bank/hmrc/history— 时间序列，单次最多 5,000 行（付费套餐）GET /api/v1/central-bank/hmrc/availability— 发布日历：银行实际发布汇率表的日期（所有套餐）
完整参数说明见 API 文档。每次请求计入套餐月度配额 — 汇率每月只变一次，本地缓存已发布的汇率表能让小配额用很久。
常见问题
HM Revenue & Customs 的汇率有 API 吗？
有 — 就是这个。官方每月 GBP 汇率，干净的 JSON；最新汇率表适用于所有套餐（含免费版）。
汇率多久更新一次？
HM Revenue & Customs 每月发布一次 — 每个日历月一张官方汇率表，在适用月份之前发布；API 在发布后很快抓取新表（最新：2026-08-01）。
这些是官方汇率吗？
是 — 取自 HM Revenue & Customs 自己发布的数据，原样提供并附银行发布日期。凡是计算而非公布的数值都会标记 derived。
