汇率查询

商品介绍

查询参考汇率（不是交易价格），可取最新值或某一天的值。不同数据源支持的基准货币和更新频率不同，见下方数据源表。 ## 数据源 请求中的 `provider` 从以下数据源中选择： - `frankfurter` (eu) - `us-treasury` (us) ## 调用与计费 - 调用 ID（`invocation_id`）由市场网关写入，请求中无需携带，携带的值会被替换。 - 只有服务返回执行成功（`data.execution.outcome` 为 `succeeded`）的调用按一次请求计费；参数错误、数据源失败和结果未知的调用不计费。 - 服务在 `data.execution.usage.units` 中报告用量，单位为 `rates`。

价格

以上为公开标价。你的组织可能有协议价，以控制台显示的价格为准。

如何使用

1. 1

   为组织开通

   在控制台为组织开通此商品。开通后即可调用，不需要你自己的厂商账号。

2. 2

   创建凭证

   在控制台“凭证”中创建一个凭证。密钥只显示一次，请保存到环境变量 ZGI_MARKET_KEY，并在每次请求中携带：

   Authorization: Bearer $ZGI_MARKET_KEY

   也可以使用 X-API-Key 请求头。一份凭证可以调用组织已开通的所有商品。

3. 3

   调用网关

   沿用厂商原有的请求与响应格式，只需把 Base URL 和密钥换成下面的值。

   Base URL

   https://market-api.zgi.im/v1/gateway/zgi-exchange-rate-standard

   curl -X POST "https://market-api.zgi.im/v1/gateway/zgi-exchange-rate-standard/v1/exchange-rate-queries" \
     -H "Authorization: Bearer $ZGI_MARKET_KEY" \
     -H "Content-Type: application/json" \
     -d '{}'

   入参与输出

   各操作的入参和输出结构，以 JSON Schema 描述。
