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.

Field Reference

status Result of the API call — success means the address was created; error means something went wrong.
address_in The unique deposit address generated by CryptAPI that you should display to your customer.
address_out Your own wallet address where the forwarded funds will ultimately be sent after the fee deduction.
callback_url The webhook URL CryptAPI will call with payment details once the transaction reaches the required confirmations.
minimum_transaction_coin Minimum payment amount in the native coin (e.g. BTC) that must be received to trigger the callback.

Implementation Example

Request
const url = "https://docs.cryptapi.io/";
const response = await fetch(url);
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data);

What Can You Build?

Note: These code examples are AI-generated and unverified. Always refer to the official API documentation for accurate usage.

Common Errors & Troubleshooting

Callback URL not reachable The URL you provided is on localhost or behind a firewall that CryptAPI servers cannot reach
Use a service like ngrok to create a temporary public URL and pass that as the callback parameter.
Invalid address format The wallet address does not match the expected format for the chosen coin
Double-check the address by pasting it into a block explorer; Bitcoin addresses start with 1, 3, or bc1.
Minimum value not met The incoming payment amount is below the coin minimum transaction threshold
Check the CryptAPI documentation for per-coin minimums, or use the /info endpoint to retrieve the current minimum dynamically.
