Lightning Address API

To send Bitcoin to a given Lightning Address, all you need to do is call the Send Lightning Address Payment API with a POST call providing the following properties:

lnAddressRecipient Lightning Address to send payment to.
amountTotal amount of satoshis to send (in millisatoshis).
commentcomment to be sent with the payment (max 150 characters).
Example: If you wish to reward 20 satoshis to a user for their completion of a challenge, and you have the user’s Lightning Address, you can use the information below to send it in 1 API call.

Sending Transaction

// Using ZBD's NodeJS SDK
import { zbd } from '@zbd/node';

// Instantiate ZBD client
const ZBD = new zbd(API_KEY_HERE);

// Set the payload
const payload = {
  amount: "20000",
  lnAddress: "",
  comment: "Sending to a Lightning Address"

// Send Lightning Address payment
try {
  const response = await ZBD.sendLightningAddressPayment(payload);
} catch(error) {
  console.log({ error });

Wow that’s easy. Welcome to instantaneous payments!

Fees are added post-send given that the routing fees for the Lightning Network are variable.(e.g if you send a 10,000 satoshi transaction to a Lightning Address and the fee ends up being 10 satoshis, the total paid by the API wallet is 10,010 satoshis).
