关于 Banco Central do Brasil (PTAX)

巴西中央银行的 PTAX 汇率是雷亚尔的官方参考汇率，由当日多次交易商询价计算，收盘公报于巴西利亚时间午后早段发布。该公报涵盖约 155 种货币，其收盘卖出价同时也是巴西海关依 Portaria MF nº 6/1999 对进口计价所用的汇率，因此巴西没有单独的税务机关汇率。

为什么使用 Banco Central do Brasil (PTAX) 官方汇率？

市场汇率实时波动，但Brazil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 Banco Central do Brasil (PTAX) 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 BRL 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/bcb/latest — 最新汇率表或单一货币对（所有套餐）
GET /api/v1/central-bank/bcb/{YYYY-MM-DD} — 任意日期的汇率表（付费套餐）
GET /api/v1/central-bank/bcb/history — 时间序列，单次最多 5,000 行（付费套餐）
GET /api/v1/central-bank/bcb/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 — 汇率每个工作日只变一次，本地缓存已发布的汇率表能让小配额用很久。

常见问题

Banco Central do Brasil (PTAX) 的汇率有 API 吗？

有 — 就是这个。官方每日 BRL 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？

Banco Central do Brasil (PTAX) 每个工作日发布一次；API 在发布后很快抓取新表（最新：2026-09-18）。

这些是官方汇率吗？

是 — 取自 Banco Central do Brasil (PTAX) 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。
