Payments API

The Payments API manages payment methods and credit purchases, backed by Stripe. Use it to add or remove cards, set a default payment method, create a payment intent for a credit purchase, and list past purchases.

Purchased credits land on your credit balance.

Payment methods

import { createNosanaClient, NosanaNetwork } from '@nosana/kit';

const client = createNosanaClient(NosanaNetwork.MAINNET, {
  api: { apiKey: process.env.NOSANA_API_KEY },
});

// Attach a payment method (id from Stripe.js) via a Stripe SetupIntent
const setupIntent = await client.api.payments.addMethod({
  paymentMethodId: 'pm_xxx',
});

// List saved payment methods
const methods = await client.api.payments.listMethods();

// Set the default, or delete one
await client.api.payments.setDefaultMethod('payment-method-id');
await client.api.payments.deleteMethod('payment-method-id');

Purchasing credits

// Create a PaymentIntent for a credit purchase
const intent = await client.api.payments.createPaymentIntent({
  amountUsd: 50,
});

// List past credit purchases
const purchases = await client.api.payments.listPurchases();
