web api is the lightweight version to the SOAP (Simple Object Access Protocol) service and usually applies REST (Representational State Transfer) as the architectural style. Nowadays, the service-oriented computing paradigm is shifting from the SOAP services to the web apis, i.e., RESTful services. Rather than hard coding from scratch, the methodology of service-oriented computing emphasizes identifying the granularity services and composing services into executable applications. Quality of Service (QoS) is always an important concern in the selection of services. The QoS driven service selection problem for service composition has been proven as NP-Complete since there are n(m) combinations for a given composite service involving m tasks with n candidate services for each task. To address this issue, this study proposes a methodology based on Genetic Algorithms for the selection of web apis. The proposed approach in this research provide several features: 1) epsilon-Pareto dominance relations are introduced to help the discrimination of composite QoS;2) the epsilon value for each dimension is determined by the AHP-based method (AHP: Analytic Hierarchy Process);and 3) the Genetic Algorithm is employed to find out the optimal combinations of web apis. Experimental results demonstrate that the proposed approach can effectively locate the combination of web apis based on the user-preferred QoS indicators without sacrificing other kinds of service quality.

web apis form the cornerstone of modern software ecosystems, facilitatingseamless data exchange and service integration. Ensuring the compatibilityand longevity of these apis is paramount. This study delves into the intricaterealm of api versioning practices, a crucial mechanism for managing apievolution. Exploring an expanded and diverse dataset of 603 293 apis spec-ifications created during the 2015-2023 timeframe and gathered from fourdifferent sources, we examined the adoption of the following versioning prac-tices: Metadata-based, URL-based, Header-based and Dynamic versioning,with one or more versions in production. api developers use more than 50different version identifier formats to encode information about the changesintroduced with respect to the previous version (i.e., semantic versioning),about when the version was released (i.e., age versioning) and about whichphase of the api development lifecycle the version belongs (i.e., stable *** releases).

Data-provisioning services can provide high value. Since data can be used and misused in unpredictable ways, organizations deal with the dilemma "to expose or not to expose" their data through web apis and - depending on the nature of their business - ponder possible opportunities and pitfalls. Rate limiting strategies are widely employed to control access to data and to safeguard back-end computational resources. However, their effectiveness depends on a good choice of the maximum allowed rate at which information can be "safely" released to clients. A relevant scenario is represented by public administrations and private companies providing services whose quality is regulated by formal business agreements on the service levels. These organizations may need to choose a rate limit for their web apis that prevent unauthorized clients to compute service levels with high confidence, while still allowing the creation of useful value-added services. In this paper, we propose a general statistical model for this problem and a technique, based on uniform sampling tools, to select an appropriate rate limit, and we demonstrate its validity through a case study involving a large bus company.

The number of web services and web apis is still growing. Due to that, the manual selection and possible manual composition of the services is difficult, which is why the research of automatic classification, selection and composition of the services is still actual. This paper reviews recent research on this topic, with the goal of defining the main topics and directions of future research. From the set of 80 read recent conference and journal articles, 30 most relevant papers were singled out. A review of the literature shows that the greatest potential lies in the topic of new services and web apis (for example, Internet of Things services, machine and deep learning services and apis) and approaches to classify, select and compose these types of services. The mentioned services have many specific features, and there are still no things, machine or deep learning as a services specific approaches in the existing literature.

To help in making sense of the ever-increasing number of data sources available on the web, in this article we tackle the problem of enabling automatic discovery and querying of data sources at web scale. To pursue this goal, we suggest to (1) provision rich descriptions of data sources and query services thereof, (2) leverage the power of web search engines to discover data sources, and (3) rely on simple, well-adopted standards that come with extensive tooling. We apply these principles to the concrete case of SPARQL micro-services that aim at querying web apis using SPARQL. The proposed solution leverages SPARQL Service Description, SHACL, DCAT, VoID, Schema. org and Hydra to express a rich functional description that allows a software agent to decide whether a microservice can help in carrying out a certain task. This description can be dynamically transformed into a web page embedding rich markup data. This web page is both a human-friendly documentation and a machine-readable description that makes it possible for humans and machines alike to discover and invoke SPARQL microservices at web scale, as if they were just another data source. We report on a prototype implementation that is available on-line for test purposes, and that can be effectively discovered using Google's Dataset Search engine.

web apis are a prominent source of machine-readable information that remains insufficiently connected to the web of Data. To enable automatic combination of Linked Data (LD) interfaces and web apis, we present the SPARQL Micro-Service architecture. A SPARQL micro-service is a lightweight SPARQL endpoint that provides access to a small, resource-centric, virtual graph, while dynamically assigning stable, dereferenceable URIs to web api resources that do not have URIs in the first place. We believe that the emergence of an ecosystem of SPARQL micro-services could enable LD-based applications to glean pieces of data from a wealth of distributed, scalable and reliable services from independent providers. We describe an experimentation where we dynamically augment biodiversity-related LD resources with data from Flickr, MusicBrainz and the Macauley scientific media library.

web Application Programming Interfaces (apis) decouple the internal implementation of a service from its consumers which can reuse and compose them to rapidly build new applications. Many web apis are described with the Openapi Specification (OAS). The goal of our research is to check the feasibility of using api descriptions found in public open source repositories to study how apis evolve over time. To do so, we collected a large dataset of OAS documents by crawling open source repositories, we parsed the corresponding metadata and measured the api size in order to extract a simple model to track the lifecycle of api artifacts and observe common evolution behaviors. Our preliminary results indicate that only a subset of the apis changes, but as opposed to the expectation that apis should only grow to maintain backward compatibility we also detected a number of apis with a more variable history. We also study the stability of api artifacts over time and whether apis are more or less likely to change as they age.

web apis contain inter-parameter dependencies that restrict the way in which input parameters can be combined to form valid calls to the service. Inter-parameter dependencies are extremely common and pervasive: they appear in 4 out of every 5 apis across all application domains and types of operations. In this demonstration paper, we present the IDL tool suite, a comprehensive collection of tools designed to facilitate dependency management in web apis. The IDL tool suite includes a specification language for inter-parameter dependencies (IDL), and OAS extension (IDL4OAS), a web editor for IDL specifications, an analysis engine (IDLReasoner), a web api for the analysis of IDL, and a website with detailed information about the tool suite and a playground. In addition to these tools, we present a catalog of applications where the IDL tool suite has already proven useful, including automated testing, code generation, and dependency-aware api gateways. We trust that the IDL tool suite will enable promising new research and applications in the area of web api management. The demo video of the IDL tool suite is available at https://***/watch?v=Hy5HYGK8Yn4.

Openapi, WADL, RAML, and api Blueprint are popular formats for documenting web apis. Although these formats are in general both human and machine-readable, only the part of the format describing the syntax of a web api is machine-understandable. Descriptions, which explain the meaning and purpose of web api elements, are embedded as natural language text snippets into documents and target human readers but not machines. To enable machines to read and process these state-of-practice web api documentation, we propose a Transformer model that solves the generic task of identifying a web api element within a syntax structure that matches a natural language query. For our first prototype, we focus on the web api integration task of matching output with input parameters and fined-tuned a pre-trained CodeBERT model to the downstream task of question answering with samples from 2,321 Openapi documentation. We formulate the original question answering problem as a multiple choice task: given a semantic natural language description of an output parameter (question) and the syntax of the input schema (paragraph), the model chooses the input parameter (answer) in the schema that best matches the description. The paper describes the data preparation, tokenization, and fine-tuning process as well as discusses possible applications of our model as part of a recommender system. Furthermore, we evaluate the generalizability and the robustness of our fine-tuned model, with the result that it achieves an accuracy of 81.46% correctly chosen parameters.

As Representational State Transfer (REST)-based web apis are spreading to enterprise information systems, software development for the use and provision of web apis is rapidly increasing. The quality of the web apis significantly influences the application quality and development productivity. However, no quality model for web apis has been established yet, because web apis differ from conventional apis in that they execute remotely on different servers and may be changed independently of their users. These unique characteristics introduce new problems in the software engineering of web apis, and impose risks to the users, especially those using enterprise web APts, whose numbers are increasing. To solve these problems, in this paper, we propose a quality model for web apis that reflects their unique characteristics. As the main characteristics of this quality model, we propose the concept of web api learnability to use and stability to change, from the perspective of web api users. Based on this quality model, we also propose a set of measures and a quantitative evaluation method. In this study, we applied the proposed quality model and evaluation method to four types of actual web apis, including Uber, WordPress, OpenStack, and Media Processing. To validate the proposed model, we also conducted an empirical study of the usability of the web apis. Our comparison of the proposed quality statistics with those from the empirical study validates the effectiveness of the proposed quality model and its associated measures of the learnability and stability of web apis.
