Overview
CryptAPI is a no-key cryptocurrency payment processor API that generates unique deposit addresses and watches for on-chain payments using a simple webhook callback URL. You provide your own wallet address and a callback URL; CryptAPI forwards the funds and notifies your server when payment arrives. It supports Bitcoin, Ethereum, Litecoin, and several other chains with no account registration required for basic use.
Beginner Tip
You do not need an account to start — just call the endpoint with your receiving wallet address and a publicly reachable callback URL. For local testing use a tunneling tool like ngrok to expose your localhost so CryptAPI can reach your webhook.
