cryptorefills-catalogconnects to the Cryptorefills MCP server for product discovery. No credentials needed — search by brand, country, category, or keyword in 10 languages.
cryptorefills-buyuses 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 interactivepurchaseElicitationmode that guides the agent step-by-step through the entire purchase — the simplest path from intent to delivered gift card.
cryptorefills-x402enables fully autonomous purchasing using thex402 protocol— HTTP 402 Payment Required as a machine-to-machine payment standard. Agents pick a settlement rail per request:Base(USDC, signed via EIP-712 / EIP-3009transferWithAuthorization; Cryptorefills relays on-chain so no ETH is needed) orSolana(USDC SPL on mainnet, partial-signed v0 transaction with the CDP facilitator as fee-payer so no SOL is needed). Either way, no account or API key.
Important: The MCP skills (cryptorefills-catalog,cryptorefills-buy) useuppercasecountry codes (US,IT,BR). The x402 skill (cryptorefills-x402) useslowercasecountry codes (us,it,br). Always use the correct case for the endpoint you're calling.
