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.
minimum_transaction_coin Minimum payment amount in the native coin (e.g. BTC) that must be received to trigger the callback.

Implementation Example

Calls a real endpoint of this API. Replace any placeholder credentials with your own key.

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

How This API Fails

We deliberately sent this API a broken request and recorded exactly what came back on 2026-08-10. Knowing the shape of an error before you hit it makes error handling much easier to write.

Common Errors & Troubleshooting

Generated guidance based on this API's documentation, not observed by us. Treat it as a starting point and check against the provider's own error reference.

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.
