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."]]
