# Quickstart

> Make your first authenticated Spritz API call in minutes.

This guide walks through your first authenticated request to the Spritz API. By the
end you'll have confirmed your credentials work and read back the authenticated user.

## Prerequisites

* A Spritz integrator account and credentials. See [Authentication](/guides/authentication)
  for how each credential type works and which one fits your integration.
* A REST client (`curl`, Postman, or your language's HTTP library).

<Note>
  Don't have credentials yet? [Get in touch](https://help.spritz.finance/en/) to set up
  an integrator account and start in the [sandbox](/guides/sandbox).
</Note>

<Note>
  The API base URL is `https://platform.spritz.finance`. All endpoints are versioned
  under `/v1`.
</Note>

## Make your first call

`GET /v1/users/me` returns the currently authenticated user. It's the simplest way to
confirm your credentials are working.

<CodeGroup>
  ```bash curl theme={null}
  curl https://platform.spritz.finance/v1/users/me \
    -H "Authorization: Bearer $SPRITZ_TOKEN"
  ```

  ```ts TypeScript theme={null}
  const res = await fetch("https://platform.spritz.finance/v1/users/me", {
    headers: { Authorization: `Bearer ${process.env.SPRITZ_TOKEN}` },
  });

  const user = await res.json();
  ```
</CodeGroup>

A successful response returns `200 OK` with the user object. If the credential is
missing or invalid you'll get a `401` [problem response](/guides/errors).
