Each Cloud API typically runs on one or more\nsubdomains of `googleapis.com`, such as `pubsub.googleapis.com`, and provides\nboth JSON HTTP and gRPC interfaces to clients over public internet and\nVirtual Private Cloud (VPC) networks. Clients can send HTTP and gRPC\nrequests to Cloud API endpoints directly or by using client libraries.\n\nCloud APIs are part of the [Google Enterprise\nAPIs](/apis/docs/resources/enterprise-apis) category in the Google Cloud console\n[API Library](https://console.cloud.google.com/apis/library/browse?filter=category:enterprise-api).\n\nThere are two kinds of Google Cloud APIs:\n\n- *Resource-based APIs*, which use the project associated with the resources\n being accessed for billing and quota.\n\n- *Client-based APIs*, which use the project associated with the client\n accessing the resources for billing and quota.\n\nAccessing Cloud APIs\n--------------------\n\nYou can access Cloud APIs from server applications with our\n[client libraries](/apis/docs/client-libraries-explained)\nin many popular programming languages, from mobile apps via the\n[Firebase SDKs](https://firebase.google.com/docs),\nor by using third-party clients. You can also access Cloud APIs with the\n[Google Cloud CLI](/sdk) or\n[Google Cloud console](https://console.cloud.google.com/).\n\nIf you are new to Cloud APIs, see [Getting Started](/apis/docs/getting-started)\non how to use Cloud APIs.\n\n### Supporting HTTP and gRPC\n\nAll Cloud APIs provide a simple JSON HTTP interface that you can call directly\nor via\n[Google API Client Libraries](https://developers.google.com/api-client-library).\nMost Cloud APIs also provide a\n[gRPC](https://grpc.io)\ninterface you can call via\n[Google Cloud Client Libraries](/apis/docs/cloud-client-libraries),\nwhich provide better performance and usability. You can also use third-party\nclients.\n\nFor more information about our client libraries, see\n[Client Libraries Explained](/apis/docs/client-libraries-explained).\n\nFor more information about authentication for using Google APIs, see\n[Authentication methods at Google](/docs/authentication) and\n[Authentication for using client libraries](/docs/authentication/client-libraries).\n\n### TLS encryption\n\nAll Cloud APIs accept only secure requests using TLS encryption.\n\n- If you are using one of our client libraries, in-transit encryption is handled for you by the library.\n- If you are using your own gRPC client, you need to authenticate with Google (which requires TLS) following the instructions in the [gRPC authentication guide](https://grpc.io/docs/guides/auth/).\n- If you are creating your own HTTP client, see our [HTTP guidelines](/apis/docs/http).\n\nYou can find out more about how traffic to Google Cloud services is secured in\nour [Encryption in Transit](/security/encryption-in-transit) security guide.\n\n### Private Service Connect\n\nEnterprise customers often want to access Cloud APIs privately for security\nand compliance reasons. You can use Private Service Connect to\nset up and manage such access within your VPC networks.\n\nFor more information, see\n[Configuring Private Service Connect](/vpc/docs/configure-private-service-connect-apis).\n\n### Step-by-step examples\n\nSee the following step-by-step guides that use the client libraries for some\npopular APIs:\n\n- [Cloud Billing Budget API with Node.js](https://console.cloud.google.com/?tutorial=billing--budget--billing-budget-api-nodejs).\n- [Cloud Billing Budget API with Python](https://console.cloud.google.com/?tutorial=billing--budget--billing-budget-api-python).\n- [Cloud Logging with Node.js](https://console.cloud.google.com/?tutorial=logging--logging-nodejs).\n- [Cloud Logging with Python](https://console.cloud.google.com/?tutorial=logging--logging-python).\n- [Cloud Logging with Go](https://console.cloud.google.com/?tutorial=logging--logging-go).\n- [Cloud Logging with Java](https://console.cloud.google.com/?tutorial=logging--logging-java).\n- [Speech-to-Text with Node.js](https://console.cloud.google.com/?tutorial=speech-to-text--speech-to-text-nodejs).\n- [Speech-to-Text with Python](https://console.cloud.google.com/?tutorial=speech-to-text--speech-to-text-python).\n- [Speech-to-Text with Go](https://console.cloud.google.com/?tutorial=speech-to-text--speech-to-text-go).\n- [Speech-to-Text with Java](https://console.cloud.google.com/?tutorial=speech-to-text__speech-to-text-java).\n\nAPI Design Guide\n----------------\n\nRegardless of the interface type, all Cloud APIs use resource-oriented design\nprinciples as described in our [API Design Guide](/apis/design), which\nensures Cloud APIs to have a simple and consistent developer experience.\nYou can reference our API Design Guide to have a better understanding of Cloud\nAPIs.\n\nIf you want to study the interface definition of Cloud APIs, you can visit the\n[Google APIs](https://github.com/googleapis/googleapis) repository on GitHub.\n\nCapping your usage\n------------------\n\nCloud APIs are shared among millions of developers and users. To ensure fair\nusage and minimize abuse risks, all Cloud APIs are enforcing rate limits and\nresource quotas on usage, commonly known as quotas. You can also use these\nquotas to control your spending on Google Cloud products by reducing your own\nquota limits. If you need more quotas than the default limits, you need\nto file quota increase requests.\n\nFor more information, see [Capping API usage](/apis/docs/capping-api-usage).\n\nMonitoring your usage\n---------------------\n\nMost Cloud APIs provide you with detailed information on your project's usage\nof that API, including traffic levels, error rates, and latencies. It helps\nyou to quickly triage problems with applications that use Cloud APIs. You can\nview this information in the Google Cloud\n[API Dashboard](https://console.cloud.google.com/apis/dashboard) in the Google Cloud console. You\ncan also create custom dashboards and alerts in Cloud Monitoring.\n\nFor more information, see [Monitoring API usage](/apis/docs/monitoring).\n\nGoogle Enterprise APIs\n----------------------\n\nGoogle Enterprise APIs are high-stability APIs, ready for enterprise use with\nsupport options available.\n\nFor more information, see\n[Google Enterprise APIs](/apis/docs/resources/enterprise-apis).\n\nTry it for yourself\n-------------------\n\n\nIf you're new to Google Cloud, create an account to evaluate how our\nproducts perform in real-world scenarios. New customers also get $300 in\nfree credits to run, test, and deploy workloads.\n[Get started for free](https://console.cloud.google.com/freetrial)"]]
