## Authenticated endpoints

There are two types of authenticated endpoints:

1. JWT authenticated endpoints
2. API key authenticated endpoints

#### Using JWT authenticated endpoints

Endpoints authenticated by a JWT can be used by first logging into your Superstate account on the [Superstate website](https://superstate.com/). Once you've logged in, you can call that endpoint in Swagger.

#### Using API key authenticated endpoints

We also provide certain endpoints that require an API key to access. To receive an API key for your entity or organization, please [contact us](https://superstate.com/contact-us).

Once you have your API keypair, you can use our [API key request npmjs package](https://www.npmjs.com/package/@superstateinc/api-key-request) to send a request using Typescript/Javascript:

```
npm install @superstateinc/api-key-request
```

If you prefer to build the request yourself, or are using a different language, the source code and instructions are located here:
