Gateway, wallet, API and operations in one product.

Every visible module is tied to a real gateway owner: checkout, invoices, wallet operations, webhooks, payouts, pricing and rail readiness.

Service catalog

Only ready rails are shown as payable.

The catalog can be broad, but checkout must only offer rails with wallet capacity, pricing, watcher and webhook readiness.

FiatCardsCard checkout remains sandbox unless a provider is configured. PricingFees And RatesFee previews use the configured fee rules.
Developers

Build against explicit contracts.

Merchant APIs stay scoped and idempotent. Admin operations stay token-protected and separated from public checkout.

Merchant integrations use scoped API keys, idempotency headers and signed webhooks. Catalog rails are broad; checkout rails must pass readiness.

Operations stay separate from buyer checkout: watchers, wallet capacity, settlements, payouts, webhooks and ledger reconciliation are admin-controlled.

Production surface

Use the API, hosted checkout and consoles from the same domain.

Keep DNS on the root ZemiaxPay domain, run Caddy in front of API and worker health, and expose only HTTPS to buyers and merchants.
