- Overall.Zipcode：查询的邮政编码。
- Overall.Overall Crime Grade：单字母等级（例如，B）。
- Overall.Violent Crime Grade、Property Crime Grade、Other Crime Grade：类别等级。
- Crime BreakDown：特定类别的比率和总数（例如，攻击、盗窃、破坏）和汇总分数。
- Crime Rates Nearby：附近邮政编码及其等级以供比较上下文。
- Similar Population Crime Rates：具有相似人口的邮政编码及其等级。
注意事项：
- 字段名称包含空格（例如，“Overall Crime Grade”）。解析JSON时，按原样访问它们。
- 数字比率的单位是服务提供的每人口指标。除非您在整个UI中一致转换，否则按返回的方式显示它们。
- 如果您的工作负载重复查询相同的邮政编码，请添加客户端缓存以减少重复调用和延迟。
Python示例：获取邮政编码并提取等级
此示例调用端点，读取总体和类别等级，并总结附近的邮政编码。将YOUR_API_KEY替换为您的真实密钥。

- 身份验证：在每个请求中使用Authorization: Bearer YOUR_API_KEY。
- 错误处理：将非2xx响应视为临时或无效输入（例如，格式错误或不支持的邮政编码）。记录状态代码和响应主体以进行故障排除。
- 超时：设置客户端超时（10-15秒是一个实用的默认值），并在网络故障时重试幂等的GET请求。
- 缓存：根据您的使用案例窗口按邮政编码缓存（例如，几小时到几天）。在后台作业中添加过期时重新验证的行为。
- UI提示：
- 等级是基于字母的；提供图例以避免歧义（例如，A最好，F最差）。
- 在显示类别总数（例如，“总财产犯罪”）时，如果存在，请包含类别分数（例如，“（B）”）。
- 为了提供上下文，使用附近邮政编码的犯罪率添加“附近邮政编码”的比较视图。
您现在可以交付的实际用例
- 财产搜索：使用财产的邮政编码在每个列表卡上显示总体等级；在详细视图中扩展到类别细分。
- 搬迁工具：对于选择的邮政编码，获取等级和附近邮政编码以推荐更安全或可比较的社区。
- 最后一公里操作：按邮政编码计算风险评分以进行路线规划和交付时间窗口。
- 租户筛查门户：在租赁申请中添加上下文邮政编码风险面板。
- 保险预报价：在收集重个人信息的表单之前，显示位置风险提示。
通过MCP从AI代理调用API
您可以通过Zyla的模型上下文协议（MCP）网关从兼容的AI代理和IDE调用此相同的端点。MCP标准化了对Claude Code、Cursor和Windsurf等工具的API访问。将您的客户端指向MCP端点，使用您的Zyla API密钥进行授权，并调用该工具，该工具向按邮政编码划分的犯罪数据API URL发出GET请求，并带有zip参数。
文档和连接细节： MCP。使用相同的Authorization: Bearer YOUR_API_KEY，并保留上述描述的确切请求URL和参数。
操作检查清单
- 输入：验证邮政编码为5位数字字符串；在调用之前拒绝或清理非数字字符。
- 可观察性：记录请求ID、邮政编码、状态代码和最小响应元数据（例如，总体等级）以用于支持仪表板。
- 退避：在临时错误或速率响应时，应用指数退避和抖动；在UI中显示后备消息。
- 安全性：将API密钥保存在服务器端秘密中；绝不要在客户端代码中暴露它。
- 数据刷新：如果您定期同步流行的邮政编码，请运行一个计划作业来预热您的缓存，以减少感知延迟。
端到端流程摘要
- 用户选择一个邮政编码，或者您从地址地理编码器推断出它。
- 您的后端调用GET https://zylalabs.com/api/824/crime-data-by-zipcode-api/583/get-crime-rates-by-zip，带有zip=XXXXX和Authorization: Bearer YOUR_API_KEY。
- 解析您需要的JSON字段：
- 顶层UI的总体等级。
- 工具提示和详细面板的犯罪细分。
- 推荐的附近邮政编码。
- 按邮政编码缓存响应；按您的计划过期。
- 在您的UI中呈现等级和比率；可选地添加链接以比较附近的邮政编码。
