# API

***

## Overview

Superstate offers APIs for all information about our tokens/funds including Net Asset Value per Share, AUM, total outstanding shares, pricing, and yield.  

| Fund  | Fund ID |
| ----- | ------- |
| USTB  | 1       |
| USCC  | 2       |
| CUSHY | 13      |
| VBDC  | 18      |

#### Key examples

The full API Spec can be found here: <https://api.superstate.com/swagger-ui/>.&#x20;

To get a specific fund's information, replace {id} with the Fund ID from the table above.

<table><thead><tr><th width="234.4453125">Endpoint</th><th>Request URL</th></tr></thead><tbody><tr><td>Daily NAV</td><td>https://api.superstate.com/v1/funds/{id}/nav-daily</td></tr><tr><td>Yield</td><td>https://api.superstate.com/v1/funds/{id}/yield</td></tr><tr><td>Holdings</td><td>https://api.superstate.com/v2/funds/{id}/holdings</td></tr></tbody></table>

## 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

Create an API key and secret from **Settings** → **Developer** in your Superstate account. See [Creating and Managing API Keys](/investors/api/api-keys.md) for step-by-step instructions.

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:
