国家数据 API 提供可靠的、最新的和结构化的全球各国信息。通过该 API，用户可以访问涵盖多个领域的综合指标集，使其成为需要将统计信息整合到项目或应用中的用户的必备资源。
可用数据包括经济方面，例如国内生产总值（GDP）、经济增长、出口和进口，以及按部门（农业、工业和服务业）划分的失业率和就业率。这些信息提供了对一个国家经济表现的洞察，并允许对时间趋势进行分析。
在社会和人口领域，该 API 提供有关总人口、人口增长、人口密度、城市化、按性别划分的预期寿命、婴儿死亡率、生育率、迁移和难民的数据。它还包括教育指标，例如按性别划分的初等、中等和高等教育的入学率，这提供了对人类发展和各国平等机会的洞察。
该 API 还包含关键的环境统计数据，包括总土地面积、森林覆盖面积、二氧化碳排放量和濒危物种，这些都是评估可持续性和环境影响的重要因素。
提供对任何国家的经济、人口、教育、环境和社会的可靠统计数据的快速访问

获取国家信息端点返回指定国家的经济、人口、教育、环境和社会统计数据 获取按国家查询城市和获取按国家查询州的端点分别返回城市和州的列表，包括名称、坐标和相关代码等详细信息
对于获取国家信息的接口，关键字段包括GDP、人口、教育入学率和二氧化碳排放。对于获取城市和州的接口，关键字段包括城市/州名称、坐标和州/国家代码
响应数据以JSON格式结构化，每个端点返回一个包含相关字段的对象。例如，GET国家信息端点提供一个包含各种统计数据的单个对象，而GET按国家获取城市则返回一个城市对象数组
获取国家信息端点提供经济、人口、教育和环境数据 获取按国家分类的城市和获取按国家分类的州端点提供地理数据，包括与特定国家代码关联的城市和州列表
获取国家信息端点通常接受国家代码作为参数以指定要检索哪个国家的数据 获取城市和获取州端点也接受国家代码以相应地过滤结果
数据来源于可靠的国际组织、政府数据库和统计机构，确保了高水平的准确性和可靠性 定期更新和交叉验证过程有助于维持数据质量
典型的应用案例包括经济分析、人口研究、教育研究和环境评估。开发人员可以将这些数据集成到应用程序中，用于可视化、报告或决策工具
用户可以解析JSON响应，以提取与其需求相关的特定字段。例如，他们可以分析随时间变化的GDP趋势或比较各国的教育入学率，从而促进明智的洞察和决策
Zyla API Hub 就像一个大型 API 商店，您可以在一个地方找到数千个 API。我们还为所有 API 提供专门支持和实时监控。注册后，您可以选择要使用的 API。请记住，每个 API 都需要自己的订阅。但如果您订阅多个 API，您将为所有这些 API 使用相同的密钥，使事情变得更简单。
价格以 USD（美元）、EUR（欧元）、CAD（加元）、AUD（澳元）和 GBP（英镑）列出。我们接受所有主要的借记卡和信用卡。我们的支付系统使用最新的安全技术，由 Stripe 提供支持，Stripe 是世界上最可靠的支付公司之一。如果您在使用卡片付款时遇到任何问题，请通过 [email protected]
此外，如果您已经以这些货币中的任何一种（USD、EUR、CAD、AUD、GBP）拥有有效订阅，该货币将保留用于后续订阅。只要您没有任何有效订阅，您可以随时更改货币。
定价页面上显示的本地货币基于您 IP 地址的国家/地区，仅供参考。实际价格以 USD（美元）为单位。当您付款时，即使您在我们的网站上看到以本地货币显示的等值金额，您的卡片对账单上也会以美元显示费用。这意味着您不能直接使用本地货币付款。
有时，银行可能会因其欺诈保护设置而拒绝收费。我们建议您首先联系您的银行，检查他们是否阻止了我们的收费。此外，您可以访问账单门户并更改关联的卡片以进行付款。如果这些方法不起作用并且您需要进一步帮助，请通过 [email protected]
价格由月度或年度订阅决定，具体取决于所选计划。
API 调用根据成功请求从您的计划中扣除。每个计划都包含您每月可以进行的特定数量的调用。只有成功的调用（由状态 200 响应指示）才会计入您的总数。这确保失败或不完整的请求不会影响您的月度配额。
Zyla API Hub 采用月度订阅系统。您的计费周期将从您购买付费计划的那一天开始，并在下个月的同一日期续订。因此，如果您想避免未来的费用，请提前取消订阅。
要升级您当前的订阅计划，只需转到 API 的定价页面并选择您要升级到的计划。升级将立即生效，让您立即享受新计划的功能。请注意，您之前计划中的任何剩余调用都不会转移到新计划，因此在升级时请注意这一点。您将被收取新计划的全部金额。
要检查您本月剩余多少 API 调用，请参考响应标头中的 "X-Zyla-API-Calls-Monthly-Remaining" 字段。例如，如果您的计划允许每月 1,000 个请求，而您已使用 100 个，则响应标头中的此字段将显示 900 个剩余调用。
要查看您的计划允许的最大 API 请求数，请检查 "X-Zyla-RateLimit-Limit" 响应标头。例如，如果您的计划包括每月 1,000 个请求，此标头将显示 1,000。
"X-Zyla-RateLimit-Reset" 标头显示您的速率限制重置之前的秒数。这告诉您何时您的请求计数将重新开始。例如，如果它显示 3,600，则意味着还有 3,600 秒直到限制重置。
是的，您可以随时通过访问您的账户并在账单页面上选择取消选项来取消您的计划。请注意，升级、降级和取消会立即生效。此外，取消后，您将不再有权访问该服务，即使您的配额中还有剩余调用。
您可以通过我们的聊天渠道联系我们以获得即时帮助。我们始终在线，时间为上午 8 点至下午 5 点（EST）。如果您在该时间之后联系我们，我们将尽快回复您。此外，您可以通过 [email protected]
为了让您有机会在没有任何承诺的情况下体验我们的 API，我们提供 7 天免费试用，允许您免费进行最多 50 次 API 调用。此试用只能使用一次，因此我们建议将其应用于您最感兴趣的 API。虽然我们的大多数 API 都提供免费试用，但有些可能不提供。试用在 7 天后或您进行了 50 次请求后结束，以先发生者为准。如果您在试用期间达到 50 次请求限制，您需要"开始您的付费计划"以继续发出请求。您可以在个人资料中的订阅 -> 选择您订阅的 API -> 定价标签下找到"开始您的付费计划"按钮。或者，如果您在第 7 天之前不取消订阅，您的免费试用将结束，您的计划将自动计费，授予您访问计划中指定的所有 API 调用的权限。请记住这一点以避免不必要的费用。
7 天后，您将被收取试用期间订阅的计划的全额费用。因此，在试用期结束前取消很重要。因忘记及时取消而提出的退款请求不被接受。
当您订阅 API 免费试用时，您可以进行最多 50 次 API 调用。如果您希望超出此限制进行额外的 API 调用，API 将提示您执行"开始您的付费计划"。您可以在个人资料中的订阅 -> 选择您订阅的 API -> 定价标签下找到"开始您的付费计划"按钮。
付款订单在每月 20 日至 30 日之间处理。如果您在 20 日之前提交请求，您的付款将在此时间范围内处理。
