Crypto payment gateway

ZemiaxPay

Accept crypto payments through hosted checkout, invoices, payment links, scoped API keys and signed webhooks on zemiaxpay.com.

Merchant workflow

Payment operations backed by verified balances and active rails.

Buyer-facing checkout only uses rails that pass wallet, pricing and watcher readiness. Operations stay separated from admin-only provider setup.

Checkout

Invoices and payment links for direct crypto collection.

Create a payment intent, show exact network instructions, detect incoming funds and notify the merchant with signed events.

Live railsUSDT/TRC20 / LTC/LTC / BTC/BTC

These rails are the current production-ready receiving paths.

Custodynon_custodial_receiving_addresses

The VPS tracks invoices and ledger entries; it does not store private keys.

API basehttps://zemiaxpay.com/api/v1

Merchant APIs require scoped keys and strict payload validation.

OpenAPI/docs-json

Use the schema for real endpoint examples and generated clients.

Developers

API, webhooks and idempotency are first-class surfaces.

Use idempotency keys on writes, verify HMAC webhook signatures, and keep admin tokens separate from merchant keys.

Pricing

Fees and quote previews come from configured rules.

The fee engine supports fixed, percentage and minimum-fee rules. Quote previews are for checkout pricing, not conversion execution.

FAQ

Operational answers before accepting real money.

Keep the dashboard and docs aligned with real runtime behavior before enabling more rails or live withdrawal broadcast.

Can buyers pay without creating an account?

Yes. Hosted checkout shows the exact asset, network, amount and receiving address for the invoice.

Does the VPS hold private keys?

No. Current live rails use non-custodial receiving addresses and ledger-backed accounting.

Are withdrawals automatic?

No. Payout planning is available, but live broadcast remains disabled until signer/provider readiness is approved.

Where do developers start?

Use the dashboard for merchant operations and the OpenAPI docs for real endpoints and payloads.
