+# QuoteAPI
+
+This application illustrates how to deploy a Server-Side Swift workload on AWS using the [AWS Serverless Application Model (SAM)](https://aws.amazon.com/serverless/sam/) toolkit. The workload is a simple REST API that returns a string from an Amazon API Gateway. Requests to the API Gateway endpoint are handled by an AWS Lambda Function written in Swift.
+
+
+## Prerequisites
+
+To build this sample application, you need:
+
+- [AWS Account](https://console.aws.amazon.com/)
+- [AWS Command Line Interface (AWS CLI)](https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-getting-started.html) - install the CLI and [configure](https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-quickstart.html) it with credentials to your AWS account
+- [AWS SAM CLI](https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/install-sam-cli.html) - a command-line tool used to create serverless workloads on AWS
+- [Docker Desktop](https://www.docker.com/products/docker-desktop/) - to compile your Swift code for Linux deployment to AWS Lambda
+
+## Build the application
+
+The **sam build** command uses Docker to compile your Swift Lambda function and package it for deployment to AWS.
+
+```bash
+sam build
+```
+
+## Deploy the application
+
+The **sam deploy** command creates the Lambda function and API Gateway in your AWS account.
+
+```bash
+sam deploy --guided
+```
+
+Accept the default response to every prompt, except the following warning:
+
+```bash
+QuoteService may not have authorization defined, Is this okay? [y/N]: y
+```
+
+The project creates a publicly accessible API endpoint. This is a warning to inform you the API does not have authorization. If you are interested in adding authorization to the API, please refer to the [SAM Documentation](https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/sam-resource-httpapi.html).
+
+## Use the API
+
+At the end of the deployment, SAM displays the endpoint of your API Gateway:
+
+```bash
+Outputs
+----------------------------------------------------------------------------------------
+Key                 SwiftAPIEndpoint
+Description         API Gateway endpoint URL for your application
+Value               https://[your-api-id].execute-api.[your-aws-region].amazonaws.com
+----------------------------------------------------------------------------------------
+```
+
+Use cURL or a tool such as [Postman](https://www.postman.com/) to interact with your API. Replace **[your-api-endpoint]** with the SwiftAPIEndpoint value from the deployment output.
+
+**Invoke the API Endpoint**
+
+```bash
+curl https://[your-api-endpoint]/stocks/AMZN
+```
+
+## Test the API Locally
+SAM also allows you to execute your Lambda functions locally on your development computer. Follow these instructions to execute the Lambda function locally. Further capabilities can be explored in the [SAM Documentation](https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/serverless-sam-cli-using-invoke.html).
+
+**Event Files**
+
+When a Lambda function is invoked, API Gateway sends an event to the function with all the data packaged with the API call. When running the functions locally, you pass in a json file to the function that simulates the event data. The **events** folder contains a json file for the function.
+
+**Invoke the Lambda Function Locally**
+
+```bash
+sam local invoke QuoteService --event events/GetQuote.json
+```
+
+## Cleanup
+
+When finished with your application, use SAM to delete it from your AWS account. Answer **Yes (y)** to all prompts. This will delete all of the application resources created in your AWS account.
+
+```bash
+sam delete
+```
