Add stablecoin payments to your site
From a payment link with no code to your own payment screen with the API. Pick how you charge and how the payment looks on your site.
Put the payment where it fits your site.
Send customers to our checkout, open it from a button, show it inside your page, or build your own with the API. Try each option below: every demo runs on this page, with sample data that can’t be paid.
Pay button
One line of HTML
Our script draws a button that opens the checkout in a window over your page, and tells your page when the payment is confirmed.

No code on your site
Send your customer to a checkout page we host. Pick one of four designs per link; no other site can frame the page.
One clean column: amount, live status, QR code and the payment details.
Open the sample checkout (opens in a new tab)<!-- Send your customer to the hosted checkout. Its design (classic, split, ticket or card) is set on the link, in the dashboard or with the API (checkoutTheme). --><a href="https://payments.cosmospay.lat/cmh9a1q7r0000l208x9k4d1pz"> Pay with Cosmos Pay</a>Payment links and QR

Create a link in the dashboard and share it by chat, email or a printed QR code. Your customer opens it and pays from their wallet.

API and SDK
Your own interface
Create payment intents from your server, draw your own payment screen and hear back through signed webhooks.
Choose an amount and send the request: the console shows what the API answers and the webhook your server receives.
Nothing leaves this page: the shapes are the API’s, the values are samples.
import { Client } from "@cosmosapp/pay_sdk"; const client = new Client({ apiKey: process.env.COSMOS_PAY_API_KEY });const intent = await client.paymentIntents.createPay({ destination: "G…YOUR_ACCOUNT", amount: "25",});// send your customer to the hosted checkoutconst checkoutUrl = "https://payments.cosmospay.lat/" + intent.id;E-commerce plugins

Create the payment on your server, share the checkout link, and let the webhook tell you when it is paid.
