How It Works

cryptorefills-catalog connects to the Cryptorefills MCP server for product discovery. No credentials needed — search by brand, country, category, or keyword in 10 languages.

cryptorefills-buy uses the same MCP server for the full purchase lifecycle: search → price → validate → order → pay → track delivery. Supports Bitcoin, Lightning, ETH, USDC, USDT, and more. Includes an interactive purchaseElicitation mode that guides the agent step-by-step through the entire purchase — the simplest path from intent to delivered gift card.

cryptorefills-x402 enables fully autonomous purchasing using the x402 protocol — HTTP 402 Payment Required as a machine-to-machine payment standard. Agents with USDC on Base and EIP-712 signing can buy without any account or API key.

Country Code Formats

Important: The MCP skills (cryptorefills-catalog, cryptorefills-buy) use uppercase country codes (US, IT, BR). The x402 skill (cryptorefills-x402) uses lowercase country codes (us, it, br). Always use the correct case for the endpoint you're calling.
