PayGate integration guide
PayGate lets Web2 merchants create agent-payable offers without building crypto payment infrastructure. API endpoints are live today; payment links and action forms are the next fulfilment modes.

1
Create a merchant account
Sign up on PayGate, choose a slug, and confirm your email. Your slug becomes the first path segment agents call.
URL
https://arispay.app/merchant-register
# After signup:
# https://paygate.arispay.app/{your-slug}/...2
Add a payout wallet
Add a primary USDC wallet in the merchant dashboard. Base mainnet is the recommended production network.

Create an API endpoint offer
Create an offer with method, path, target URL, and price in integer cents. The current API keeps the internal merchant-products route while PayGate presents it as an offer in the dashboard.
curl
curl -X POST https://api.arispay.app/v1/merchants/me/products \

Agents call the PayGate URL
Agents using PayAgent or another x402-compatible client receive a 402, sign the payment, retry, and get your origin response after settlement.
