# Welcome to CDP API

> Crypto infrastructure all in one place

## Your one-stop shop for crypto infrastructure

The Coinbase Developer Platform (CDP) is your one-stop shop for crypto infrastructure. One API key unlocks the full suite: accept payments, issue stablecoins, create wallets, execute trades, build with onchain tools, and onboard customers to Coinbase's compliance program. No blockchain complexity required.
