Every payment handler stores expose to agents over the Universal Commerce Protocol: wallets like Shopify Pay, Google Pay, and Apple Pay, and processors like Stripe and PayPal. Each handler shows how many verified stores currently accept it, updated every 24 hours.
Shopify's accelerated checkout and stored-credential wallet.
Google's tokenized wallet, common for fast agent checkout.
Apple's tokenized wallet for one-tap authorization.
We attribute each handler from the payment methods a store declares in its UCP manifest. If a handler you expect isn't listed, no verified store has declared it yet. Run a live check on any store to have its handlers attributed immediately.
