# What is Grid?

![What is Grid hero](https://mintcdn.com/agents-docs/qL8kqlSYbvexR8cg/images/heroes/hero-what-is-grid-light.svg?fit=max\&auto=format\&n=qL8kqlSYbvexR8cg\&q=85\&s=fafa500fa08205adae1e5f47fab0167d)

Grid is a low-level payment infrastructure API that enables modern financial institutions, businesses, or any developer to send, receive, and settle value globally across fiat currencies, stablecoins, and Bitcoin. With a single, simple API, you can build applications that move money instantly across borders without the complexity of orchestrating multiple payment rails or currencies.

## Features

No Crypto Headaches

We handle all the on-chain logic, wallet ops, and conversions so you don't have to.

## What to build

Our APIs are intentionally low-level, giving developers, institutions, and businesses control over what they build. Fiat, stablecoins, or other digital assets.

Developers use them for things like issuing cards, creating virtual accounts and wallets, collecting payments, and sending payouts. You might receive stablecoins and pay out pesos to a bank account, or let customers spend from an account with a card.

The APIs work across assets and payment rails. We expose the primitives for moving money between accounts, wallets, and sources of liquidity around the world. You decide how to put them together.
