클라이언트 애플리케이션에서 API를 호출할 때 전달하는 코드입니다. API 키는 API를 호출하는 애플리케이션 또는 Google Cloud 프로젝트를 식별합니다. Endpoints API에서 API 키를 사용하는 방법에 대한 자세한 내용은 API 키를 사용하는 경우 및 조건을 참고하세요.
Extensible Service Proxy(ESP)는 OpenAPI 또는 gRPC API 백엔드 앞에서 실행되는 확장 가능한 Nginx 기반 고성능 프록시로, 인증, 모니터링, 로깅과 같은 API 관리 기능을 제공합니다. 자세한 내용은 Endpoints 정보 및 Endpoints: 아키텍처 개요를 참조하세요.
Extensible Service Proxy V2 (ESPv2)는 OpenAPI 또는 gRPC API 백엔드 앞에서 실행되는 확장 가능한 Envoy 기반 고성능 프록시로, 인증, 모니터링, 로깅과 같은 API 관리 기능을 제공합니다. 자세한 내용은 Endpoints 정보 및 Endpoints: 아키텍처 개요를 참조하세요.
Google이 개발한 고성능 오픈소스 범용 RPC 프레임워크입니다.
gRPC에서 클라이언트 애플리케이션은 다른 머신의 서버 애플리케이션에 있는 메소드를 로컬 객체처럼 직접 호출할 수 있습니다. Endpoints와 함께 gRPC 사용에 대한 자세한 내용은 gRPC API용 Cloud Endpoints를 참조하고 일반적인 내용은 gRPC 웹사이트를 참조하세요.
Kubernetes 클러스터에 명령어를 실행하기 위한 명령줄 인터페이스입니다. Kubernetes 또는 Google Kubernetes Engine 클러스터에서 Endpoints용 API를 배포할 때 kubectl을 사용합니다.

API\n keys identify the application or the Google Cloud project making\n the call to the API. See\n [Why and when to use API keys](/endpoints/docs/openapi/when-why-api-key)\n for more information on using an API key with your Endpoints API.\n\nAuth0\n: A service that lets you define how users authenticate to applications. See\n [Auth0](https://auth0.com) for more information.\n\nCloud Endpoints Frameworks\n: Endpoints Frameworks for the App Engine standard environment\n consists of tools, libraries, and capabilities that let you generate APIs and\n client libraries from an App Engine application. See\n [About Endpoints Frameworks](/endpoints/docs/frameworks/java/about-cloud-endpoints-frameworks)\n for more information.\n\ncontainer\n: A software package that contains the libraries, frameworks, and settings.\n that an application requires to run. See\n [What is a container](https://www.docker.com/what-container)\n for more information.\n\nCORS\n: Cross-Origin Resource Sharing (CORS) is a specification that provides a way\n for web applications to access resources on a server in another domain\n (technically, in another origin). To learn more about CORS, see the\n [Mozilla Developer Network (MDN) web docs](https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS)\n and the [Fetch Living Standard](https://fetch.spec.whatwg.org/).\n\nDocker\n: Open source software that lets you automate deploying applications inside\n software containers. See [What is Docker](https://www.docker.com/what-docker)\n for more information.\n\nExtensible Service Proxy\n: The Extensible Service Proxy (ESP) is an Nginx-based high-performance, scalable proxy\n that runs in front of an OpenAPI or gRPC API backend and provides API management\n features such as authentication, monitoring, and logging. See\n [About Endpoints](/endpoints/docs/openapi/about-cloud-endpoints)\n and\n [Endpoints: Architectural overview](/endpoints/docs/openapi/architecture-overview)\n for more information.\n\nExtensible Service Proxy V2\n\n: The Extensible Service Proxy V2 (ESPv2) is an [Envoy](https://www.envoyproxy.io/docs/envoy/latest/)-based\n high-performance, scalable proxy that runs in front of an OpenAPI or gRPC API backend and provides API management\n features such as authentication, monitoring, and logging. See\n [About Endpoints](/endpoints/docs/openapi/about-cloud-endpoints)\n and\n [Endpoints: Architectural overview](/endpoints/docs/openapi/architecture-overview)\n for more information.\n\n: ESPv2 supports version 2 of the\n [OpenAPI Specification](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/2.0.md) and [gRPC](http://www.grpc.io) Specifications.\n\nFirebase authentication\n\n: Google's authentication service that supports end user sign-in for client\n applications by using credentials from popular federated identity providers\n such as Google, Facebook, or Twitter. See\n [Firebase authentication](https://firebase.google.com/docs/auth/)\n for more information.\n\nGoogle ID token\n\n: A JSON Web Token (JWT) that contains the [OpenID\n Connect](https://developers.google.com/identity/protocols/OpenIDConnect)\n fields needed to identify a Google user account or service account, and that\n is signed by Google's authentication service, `https://accounts.google.com`.\n\ngRPC\n\n: A high performance, open source universal RPC framework developed by Google.\n In gRPC, a client application can directly call methods on a server application\n on a different machine as if it was a local object. See\n [Cloud Endpoints for gRPC APIs](/endpoints/docs/grpc/about-grpc)\n for information on using gRPC with Endpoints and the\n [gRPC](http://www.grpc.io)\n website for general information.\n\nJWT\n\n: JSON Web Token is an open standard access token format for use in HTTP\n Authorization headers and URI query parameters. See\n [Introduction to JSON Web Tokens](https://jwt.io/introduction/) for general\n information.\n\nkubectl\n\n: A command-line interface for running commands against Kubernetes clusters. You\n use `kubectl` when deploying an API for Endpoints on a Kubernetes\n or\n [Google Kubernetes Engine](/kubernetes-engine/docs/clusters)\n cluster.\n See [Overview of `kubectl`](https://kubernetes.io/docs/user-guide/kubectl-overview/)\n for more information.\n\nKubernetes\n\n: Open source software that lets you automate the deployment, management,\n and scaling of containerized applications across clusters of hosts.\n See [Kubernetes](https://kubernetes.io/) for more information.\n\nNGINX\n\n: An open source, high-performance HTTP server and service proxy that\n ESP is based on. See the\n [NGINX Wiki](https://www.nginx.com/resources/wiki/)\n for more information. For information on ESP, see\n [About Cloud Endpoints](/endpoints/docs/openapi/about-cloud-endpoints)\n and [Endpoints: Architectural overview](/endpoints/docs/openapi/architecture-overview).\n\nOpenAPI\n\n: The [Open API Initiative](http://openapis.org) is an industry-wide effort to\n standardize the description of REST APIs. APIs that are described with the\n [OpenAPI Specification](https://github.com/OAI/OpenAPI-Specification) (formerly\n the [Swagger Specification](http://swagger.io)) can be supported with common\n tools that create documentation, automate testing, and generate code for clients\n and servers. See\n [OpenAPI overview](/endpoints/docs/openapi/openapi-overview)\n for more information.\n\nOpenAPI document\n\n: A configuration file in either YAML or JSON format that you use to describe\n your API.\n\nsurface\n\n: The public interface of an API. An API's surface consists of the methods\n as well as the parameters and return types used in the methods."]]
