# Overview

API access requires an API User. To get started, [create an API User](/developers/getting-started/create-an-api-user). This step results in an API Access Token for the API User.

An API User is sufficient for read-only actions or actions that do not require automated access to your MPC share, such as creating vaults.

If you intend to create transactions, you also need to [set up an API Signer](/developers/getting-started/set-up-an-api-signer). The Signer signs the transactions created by the API User.
