Alternatives
Alternative to card checkout for agentic game commerce, with explicit x402, MCP, and delivery recovery contracts.
Alternative to Card Checkout
Use this gateway when the buyer is an autonomous agent that can inspect a 402 challenge, sign or fund the payment, retry the same request, and poll settlement or delivery state without a browser-hosted card checkout.
Alternative to One-Off Game Integrations
Direct one-off integrations can work, but usually increase maintenance and reduce interoperability compared with a discovery-first gateway that publishes OpenAPI, MCP, llms.txt, skill.md, pricing, status, and webhook docs.
When Not To Use It
Do not use Clash of Coins checkout as a generic PSP, a chargeback-managed card vault, or a delivery API for unrelated games. It is intentionally scoped to Clash of Coins sale and shop commerce.
