## API Usage > **TL;DR** Get the WHOIS records for a site: `curl https://who-dat.as93.net/example.com` For detailed request + response schemas, and to try the API out, you can reference the [spec](https://who-dat.as93.net/docs.html) ### Base URL The base URL for the public API is [`who-dat.as93.net`](https://who-dat.as93.net) If you're self-hosting (recommended) then replace this with your own base URL. ### Endpoints

Single Domain Lookup `/[domain]`

[![Who-Dat Swagger Docs](https://img.shields.io/badge/Swagger-Docs-85EA2D?style=for-the-badge&logo=swagger&labelColor=1b2744&link=https%3A%2F%2Fwho-dat.as93.net%2Fdocs.html)](https://who-dat.as93.net/docs.html) --- ## Deployment #### Option 1: Vercel This is the quickest and easiest way to get up-and-running. Simply fork the repository, then login to Vercel (using GitHub), and after importing your fork, it will be deployed! There's no additional config or keys needed, and it should work just fine on the free plan. Alternatively, just hit the button below for 1-click deploy 👇 [![1-Click Deploy to Vercel](https://img.shields.io/badge/Deploy-Vercel-ffffff?style=for-the-badge&logo=vercel&labelColor=1b2744&link=https%3A%2F%2Fwho-dat.as93.net%2Fdocs.html)](https://vercel.com/new/clone?repository-url=https%3A%2F%2Fgithub.com%2Flissy93%2Fwho-dat&demo-title=Who-Dat%20Demo&demo-url=https%3A%2F%2Fwho-dat.as93.net&demo-image=https%3A%2F%2Fi.ibb.co%2FJ5r1zCP%2Fwho-dat-square.png) #### Option 2: Docker The light-weight Docker image is published to DockerHub ([hub.docker.com/r/lissy93/who-dat](https://hub.docker.com/r/lissy93/who-dat)), as well as GHCR ([here](https://github.com/Lissy93/who-dat/pkgs/container/who-dat)). Providing you've got Docker installed, you can get everything by running: ```shell docker run -p 8080:8080 --dns 8.8.8.8 --dns 8.8.4.4 lissy93/who-dat ``` [![Deploy from Docker](https://img.shields.io/badge/Deploy-Docker-2496ED?style=for-the-badge&logo=docker&labelColor=1b2744&link=https%3A%2F%2Fwho-dat.as93.net%2Fdocs.html)](https://hub.docker.com/r/lissy93/who-dat) #### Option 3: Binary Head to the [Releases Tab](https://github.com/Lissy93/who-dat/releases), download and extract the pre-built executable for your system, then run it.

Example

If you're using the command line, you can do something like this
Don't forget to update (v1.0) with the version number you want, and (linux-amd64) with your system's architecture. ```bash # Download the binary for your system (from releases tab) wget https://github.com/Lissy93/who-dat/releases/download/v0.9/who-dat-v0.9-linux-amd64.tar.gz -O ./who-dat.tar.gz # Extract the compressed file tar -xzvf who-dat.tar.gz # Make it executable chmod +x who-dat # Run Who-Dat! ./who-dat ``` (Or, if you're a Microsoft fanboy, you can just double-click the `who-dat.exe` after extracting in Windows Explorer)

#### Option 4: Build from Source Follow the setup instructions in the [Development](#development) section.
Then run `go build -a -installsuffix cgo -o who-dat .` to generate the binary for your system.
You'll then be able to execute the newly built `./who-dat` file directly to start the application. --- ## Authentication Authentication is optional, and can be enabled by setting the `AUTH_KEY` environment variable. When authentication is enabled, all API requests must include the key in the Authorization header, using one of the formats indicated below. #### Raw API Key ``` curl -H "Authorization: your-secret-key" https://who-dat.yourdomain.com/example.com ``` #### Bearer Token Format ``` curl -H "Authorization: Bearer your-secret-key" https://who-dat.yourdomain.com/example.com ``` If authentication is not configured (no `AUTH_KEY` set), the API will remain publicly accessible. --- ## Development Prerequisites: You'll need [Go](https://go.dev/) and [Node](https://nodejs.org/) installed. You will likley also want [Git](https://git-scm.com/) and/or [Docker](https://www.docker.com/). ``` git clone git@github.com:Lissy93/who-dat.git cd who-dat go get npm install npm run build ``` Then run either `npx vercel dev`, or `go run main.go` Alternativley, build the Docker container with `docker build -t who-dat .` [![Open in GitPod](https://img.shields.io/badge/GitPod-Try_Live-FFAE33?style=for-the-badge&logo=gitpod&labelColor=1b2744&link=https%3A%2F%2Fcodeberg.org%2Falicia%2Fwho-dat)](https://gitpod.io/#https://github.com/lissy93/who-dat) [![Open in VS Code](https://img.shields.io/badge/CodeSpaces-Try_Live-007ACC?style=for-the-badge&logo=visualstudiocode&labelColor=1b2744&link=https%3A%2F%2Fcodeberg.org%2Falicia%2Fwho-dat)](https://codespaces.new/Lissy93/who-dat) --- ## Web Interface There's a very simple frontend included in the app. This is built with Alpine.js, so is super light-weight, and only adds about 100kb to the total executable. The web interface is used to view WHOIS records for a given domain, and also hosts the API documentation.
