Grafbase
The Grafbase GraphQL Federation Gateway
Grafbase is an open-source GraphQL federation gateway and API platform designed to unify multiple backend services and data sources into a single, high-performance GraphQL interface. The project provides a Rust-based gateway that acts as the central layer for composing and managing distributed APIs, particularly in microservice architectures where data may come from many independent systems. By supporting GraphQL federation standards, the platform enables teams to combine multiple subgraphs or services into a unified schema that clients can query as a single endpoint. Grafbase is designed for large-scale production environments, emphasizing high throughput, low latency, and efficient resource usage through its Rust implementation. The system also includes tools for schema governance, API lifecycle management, and collaboration workflows, helping engineering teams safely evolve complex APIs over time. -

NetSuite PHP API Client
NetSuite PHP API Client with namespaces and autoloading
A PHP API client package for NetSuite, pried from the NetSuite PHP Toolkit and made more consumable for modern PHP application development. All of the classes in the NetSuite\Classes namespace are code provided by NetSuite with a license allowing redistribution. The custom work provided by this library separates these nearly 2,000 classes out into their own files and allows the classes to be installed with composer and accessed using standard autoloading support. It allows configuration to be read from the environment, adds support to log requests and responses and provides a simplified client wrapper class (NetSuiteService). You can alternatively place your config in environment variables. This is helpful in hosted environments where deployment of config files is either not desired or practical. You can find the valid keys in the included .env.example file with sample values. -

Nodejs Expressjs MongoDB API Project
A boilerplate for REST API Development with Node.js, Express, etc.
A ready-to-use boilerplate for REST API Development with Node.js, Express, and MongoDB. This is a basic API skeleton written in JavaScript ES2015.

Ocelot
.NET core API Gateway
Ocelot is a .NET API Gateway. This project is aimed at people using .NET running a micro services / service-oriented architecture that need a unified point of entry into their system. However, it will work with anything that speaks HTTP and run on any platform that ASP.NET Core supports. Ocelot manipulates the HttpRequest object into a state specified by its configuration until it reaches a request builder middleware where it creates a HttpRequestMessage object which is used to make a request to a downstream service. The middleware that makes the request is the last thing in the Ocelot pipeline. It does not call the next middleware. The response from the downstream service is retrieved as the requests goes back up the Ocelot pipeline. There is a piece of middleware that maps the HttpResponseMessage onto the HttpResponse object and that is returned to the client. That is basically it with a bunch of other features! -

Octokit
Ruby toolkit for the GitHub API
API wrappers should reflect the idioms of the language in which they were written. Octokit.rb wraps the GitHub API in a flat API client that follows Ruby conventions and requires little knowledge of REST. Most methods have positional arguments for required input and an options hash for optional parameters, headers, or other options. While most methods return a Resource object or a Boolean, sometimes you may need access to the raw HTTP response headers. Access tokens can be revoked, removing access for only that token without having to change your password everywhere. Access tokens have access scopes that allow for more granular access to API resources. For instance, you can grant a third party access to your gists but not your private repositories. Two-Factor Authentication brings added security to the account by requiring more information to login. -

OpenAI-Java
OpenAI Api Client in Java
OpenAI-Java is the official Java client library provided by OpenAI for interacting with the OpenAI API. It is designed to make it easier for Java applications to call endpoints like chat completions, embeddings, function calling, streaming, and other model services using idiomatic Java patterns. You configure the client (often via environment variables or system properties), then build parameter objects (e.g. ChatCompletionCreateParams) and invoke methods like client.chat().completions().create(...) to send requests in a type-safe way. The library also supports streaming APIs, where the response arrives in chunks, using helpers like ChatCompletionAccumulator to accumulate partial responses into a full object. For complex use cases (e.g. structured outputs, function calling), it provides schema support, JSON annotations, and schema validation. -

Swagger Core
Examples, server integrations for generating Swagger API Specification
Swagger Core is a Java implementation of the OpenAPI Specification. Current version supports JAX-RS2 (javax and jakarta namespaces). One of the common usage scenarios is to integrate swagger-jaxrs2 into an existing or new JAX-RS based project ("code-first"), to automatically provide and expose its APIs definition, which is kept in sync during the project lifecycle. Such definition can be the base for further processing/consumption, including API documentation (e.g with swagger-ui, API client generation in various languages (e.g with swagger-codegen), custom processing, and so on. Such result is achieved by scanning JAX-RS resources and resolving their operations and used types, (also) processing applied annotations (e.g. Swagger, JAX-RS, Jackson, JAXB, etc.). An extension mechanism allows to further customize and pre/post processing result. -

The Lura Project framework
Ultra performant API Gateway with middlewares
An extendable, simple and stateless high-performance API Gateway framework designed for both cloud-native and on-prem setups. Consumers of REST API content (specially in microservices) often query backend services that weren’t coded for the UI implementation. This is of course a good practice, but the UI consumers need to do implementations that suffer a lot of complexity and burden with the sizes of their microservices responses. Lura is an API Gateway builder and proxy generator that sits between the client and all the source servers, adding a new layer that removes all the complexity to the clients, providing them only the information that the UI needs. Lura acts as an aggregator of many sources into single endpoints and allows you to group, wrap, transform and shrink responses. Additionally it supports a myriad of middlewares and plugins that allow you to extend the functionality, such as adding Oauth authorization or security layers.
