KuCoin Pay vs Strike API

KuCoin Pay is a cryptocurrency payment solution for consumers and merchants, supporting online, offline, and in-app transactions. Checkout options include API integration, hosted KuCoin Pay checkout, and QR codes. Payments can be made on-chain from exchanges or decentralized wallets; verified KuCoin users can also make gas-free off-chain payments to each other. Consumer payments settle instantly, and access is for verified KuCoin users. Merchants apply with business information, complete verification, sign an agreement, and integrate the API. They can settle in stablecoins such as USDT or USDC, or convert crypto earnings to fiat through KuCoin OTC. A merchant portal provides transaction monitoring, financial reporting, and customer insights. KuCoin describes merchant compliance measures including AML/KYC protocols, anti-fraud monitoring, and Travel Rule support through solutions such as Sumsub. The service supports web, iOS, and Android. Consumer payments cost nothing, though merchants may apply handling fees. Merchant pricing is volume-based and available on request. KuCoin Pay is linked to the main KuCoin account, so suspension of that account also suspends KuCoin Pay.

Strike API is a paid, HTTP-based REST-style API for programmatic cash and bitcoin transactions. It works across the Bitcoin blockchain and Lightning Network, with cash payouts to external bank accounts. Businesses can send, receive, exchange, and direct payments, create invoices or receive requests, and credit incoming funds to a Strike account as cash or bitcoin. Checkout options include Lightning invoices, on-chain Bitcoin addresses, QR codes, and receive requests; settlement can be cash, bitcoin, or both. OAuth Connect lets users authorize third-party applications within granted permissions and scopes, while webhooks notify applications about supported events. Authentication uses a non-expiring account API key or an expiring OAuth access token. The browser API Explorer can send requests and supplies cURL, Go, Python, and Node.js examples. A sandbox uses simulated balances and testnet bitcoin. Business accounts, regional availability, and verification are required. Pricing is on request.
