一句话：分析微服务与 RESTful API 市场中，服务等级协议（SLA）和按成本定制的限制如何塑造 API 服务供给。
随着软件架构设计向微服务范式演进，RESTful API 被确立为构建应用的首选方案。在这一趋势下，API 市场持续增长，提供商通常会基于成本等因素提供不同服务等级，并针对每个等级设置定制化的限制条件。论文围绕限制（limitations）与 SLA 在 API 产业中的作用展开，探讨它们如何参与 API 服务的分级、供给与产业生态。摘要仅给出这一背景与议题，未提供具体研究方法、形式化模型或实验评估。
As software architecture design is evolving to a microservice paradigm, RESTful APIs are being established as the preferred choice to build applications. In such a scenario, there is a shift towards a growing market of APIs where providers offer different service levels with tailored limitations typically based on the cost.
