SkillDescription
cryptorefills-catalogSearch and explore 10,500+ gift cards, mobile top-ups, and eSIMs across 180+ countries via MCP. Multi-language, real-time pricing, no account required.
cryptorefills-buyFull purchase workflow via MCP — interactive guided elicitation, fixed and range-based pricing, multi-product orders, all crypto payment methods. No CLI install needed.
cryptorefills-x402Autonomous agent commerce via x402 protocol. Two settlement rails: USDC on Base (EIP-3009) or USDC SPL on Solana mainnet (partial-signed v0 transaction). No account, no OAuth, no API key, and no native gas needed on either rail. For AI agents with a Base or Solana wallet.

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 pick a settlement rail per request: Base (USDC, signed via EIP-712 / EIP-3009 transferWithAuthorization; Cryptorefills relays on-chain so no ETH is needed) or Solana (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.

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.
