How to Add Payments to a Vibe-Coded Site — Lovable, v0, Bolt, Cursor, Framer, Webflow, Wix

You prompted Lovable, v0, Bolt, Cursor, or Claude into scaffolding a peptide / nutra / supplements shop in a weekend. The front-end looks clean, the hero section converts, the product grid renders — and then you hit "accept payments" and everything stops. Stripe rejects the vertical. PayPal auto-bans. The AI builder's default payment panel doesn't even offer an "other" option. If you've got an AI-generated ("vibe-coded") website and a restricted-category product, the payment integration problem is the only real remaining blocker. This guide walks through how to ship card + Apple Pay + USDC checkout on Lovable, v0, Bolt, Cursor, Replit, Claude, Framer, Webflow, Wix, Squarespace, Carrd, or any other AI-scaffolded or no-code builder — using Peptide-Pay at 3% flat, no LLC, no rolling reserve, same-day go-live.

Why AI-generated and no-code sites break at the payment step

Every current AI site builder (Lovable, v0 by Vercel, Bolt.new, Cursor, Claude Code's scaffolding, Replit's Agent) defaults to Stripe for payments because Stripe's SDK is the most-tokens-of-training- data payment API on the internet. When an LLM is asked to "add a checkout", it emits a Stripe code block by default. No-code platforms (Wix Payments, Squarespace Payments, Webflow Ecommerce, Framer Forms) wrap their own Stripe- or Adyen-backed rails — same backend. All of them share one property: they banMCC 5122 (drugs, druggists' sundries), MCC 5912 (pharmacy), and the restricted-business lists that contain peptides, research chemicals, SARMs, nutra, and adjacent categories.

The practical result for an AI-generated peptide shop: you build a polished frontend in an afternoon, you paste the Stripe key, you launch, you get your first 3 sales, Stripe Radar flags your descriptor ("Retatrutide", "BPC-157", "semaglutide reconstitution kit"), and your account is terminated on a Friday. Funds freeze for 180 days. The $2,000 AI-builder bill is wasted.

Peptide-Pay as a drop-in for any AI-built or no-code site

Peptide-Pay is deliberately designed for vibe-coded sites. The public surface is three primitives — payment link, npm SDK, WooCommerce plugin — and one of the three fits every AI builder and no-code platform on the market:

• Static HTML / no-code / AI prompt output: generate a payment link in the dashboard, paste it into any <a href="…">. Works on Squarespace, Wix, Webflow (free plan), Framer, Carrd, Google Sites, Notion Sites — anything that renders an anchor tag.
• AI-scaffolded Next.js / React / SvelteKit: npm install github:kinerette/peptide-pay-sdk, call the SDK from any route handler / server action / edge function. The SDK shape mirrors Stripe, so when you prompt "replace Stripe with Peptide-Pay", the LLM rewrites correctly on the first pass.
• WooCommerce shop: install the plugin, paste your API key + wallet, activate.

Platform-by-platform: Lovable, v0, Bolt, Cursor, Claude

Lovable

Lovable prompts a Next.js app. Ask: "Replace the Stripe checkout with Peptide-Pay. Install the SDK with npm install github:kinerette/peptide-pay-sdk. Read the API key from env PEPTIDEPAY_API_KEY. In the checkout route, create a session with the order total in cents and redirect to session.url." Lovable writes the route handler below, then scaffolds a webhook route at /api/pp-webhook.

v0 (Vercel)

v0 generates component-first output. Ask v0 for the checkout component and it will emit a button calling a server action — same SDK shape as Lovable. Paste your API key into the Vercel project environment variables panel.

Bolt.new (StackBlitz)

Bolt.new runs Next.js in WebContainer. The integration is identical to Lovable's — same npm install, same route handler. Bolt will hot-reload your checkout page once the env var is set. You can deploy straight to Vercel from the Bolt UI.

Cursor / Claude Code / Continue.dev

Inline-prompt the IDE: "Add Peptide-Pay checkout using the npm package. Stripe-compatible API shape. Route at/api/checkout, redirect to the session URL." Any 2024+ LLM has Stripe patterns in context; the Peptide-Pay SDK maps 1:1, so the output compiles first try.

// One route replaces your entire Stripe checkout.
// npm install github:kinerette/peptide-pay-sdk
// Works identically in: Lovable, v0, Bolt, Cursor, Claude Code,
// Replit Agent, Next.js, Remix, SvelteKit, Nuxt, Astro, Hono.

import { PeptidePay } from 'peptide-pay';

const pp = new PeptidePay(process.env.PEPTIDEPAY_API_KEY!);

// POST /api/checkout
export async function POST(req: Request) {
  const { items } = await req.json();
  const amountCents = items.reduce(
    (sum: number, it: { price: number; qty: number }) => sum + it.price * it.qty, 0
  );

  const session = await pp.checkout.sessions.create({
    amount_cents: amountCents,
    currency: 'USD',
    success_url: `${process.env.SITE_URL}/thanks`,
    cancel_url:  `${process.env.SITE_URL}/cart`,
    webhook_url: `${process.env.SITE_URL}/api/pp-webhook`,
    metadata: { items: JSON.stringify(items) },
  });

  return Response.redirect(session.url, 303);
}

Framer, Webflow, Wix, Squarespace, Carrd — the payment-link path

No-code / low-code platforms don't expose a backend you can npm installinto. The answer on those platforms is Peptide-Pay's hosted payment links: generate one in the merchant dashboard, paste it into the button element's destination URL.

• Framer: select the CTA button → Link → External → paste the payment link.
• Webflow:open the button's settings → Link URL → paste. Set target to the current tab.
• Wix: Button Settings → Link → Web Address → paste.
• Squarespace: Button Block → Clickthrough URL → paste.
• Carrd: Button element → URL → paste.

The buyer lands on the Peptide-Pay hosted checkout page (a clean, white-labeled UI at pay.peptide-pay.com/session/…), picks a payment method (Apple Pay / Visa / Mastercard / SEPA / USDC), and completes. The merchant gets a webhook even without a backend — dashboard email alerts and Zapier / Make integrations fire on payment.completed.

Peptide-Pay vs native payment on each platform

Ship first, incorporate later — the vibe-coder sequence

One reason AI-builder adoption has outpaced legacy platforms so fast is that it compresses "idea to live site" from weeks to hours. Peptide-Pay is deliberately built to preserve that speed at the payment step. In particular:

• No LLC required to start.You connect a Polygon wallet you personally own. You incorporate later, once revenue justifies it — same sequence the best indie hackers already use, just without Stripe's gatekeeping.
• No processing history required.High-risk PSPs (CCBill, AllayPay) require 6–12 months of prior card processing as part of their underwriting. For a vibe-coded shop that just launched, that's a chicken-and-egg problem. Peptide-Pay skips it — there's no underwriting because the processor is non-custodial.
• Same-day go-live. Median time from signup to first live sale is under 15 minutes. For context: the incumbent high-risk PSP flow (CCBill, SanctusPay, Instabill) is 2–4 weeks of onboarding paperwork before you can take a single card.

Compliance reminder for AI-built shops

The speed of AI scaffolding cuts both ways: it makes it easy to launch a shop, including an illegal one. Peptide-Pay provides the payment rail, not a compliance layer. You as the merchant of record are responsible for:

• Product legality in every jurisdiction you ship to.
• FDA-style "research compound" disclaimer wording, no-human-use language, age-gating.
• Your own sales tax, VAT, or GST collection and remittance.
• Prescription status: semaglutide / tirzepatide / GLP-1s are prescription-only in most jurisdictions — selling them directly without a licensed prescribing clinic is the regulatory trap most AI-built shops fall into.

Peptide-Pay's TOS explicitly excludes prescription drug sale. We're built for peptides sold as research compounds, for nutra, for SARMs (where legal), for supplements — not for a shop that effectively prescribes without a doctor. If your AI-generated shop is about to ship prescription-only drugs without a prescribing licensee, you need a teleconsultation-as-a-service layer, not just a payment rail.

Get started on any vibe-coded or no-code platform

1. Sign up — one field, Polygon wallet address.
2. Choose the integration path: payment link (no-code), SDK (AI-scaffolded), or plugin (WooCommerce).
3. Ship. Read the full Integrate guide and the Docs if you want deep options — most vibe-coded shops never need more than the 10-line SDK snippet above.
