# API Concepts Overview

> An overview of accounts, addresses, transfers, automations, and other key resources in the Brale API.

* [Accounts](https://docs.brale.xyz/key-concepts/accounts.md) - Your customers
* [Addresses](https://docs.brale.xyz/key-concepts/addresses.md) - A single resource that represents both onchain wallet addresses and offchain fiat accounts. Use `address_id` everywhere a source or destination is needed.
* [Financial Institutions (Legacy)](https://docs.brale.xyz/key-concepts/financial-institutions.md) - Financial accounts that can receive or send funds. Kept for backwards compatibility - new integrations should use Addresses.
* [Transfers](https://docs.brale.xyz/key-concepts/transfers.md) - Convert into, out of, and between stablecoins and fiat
* [Automations](https://docs.brale.xyz/key-concepts/automations.md) - A unique bank account number that will send deposited fiat funds to a pre-set onchain address
* [Idempotency](https://docs.brale.xyz/key-concepts/idempotency.md) - Ensure each POST request is processed only once
