How do AI agents buy gift cards with crypto?

AI agents connect to the Cryptorefills MCP server and use structured tool calls to discover a brand, pick a denomination, validate the order and pay in stablecoins or Bitcoin. No checkout UI, no forms to fill. Once the onchain payment is confirmed, the agent receives the delivery code or voucher.

Which AI agents support Cryptorefills MCP?

Any MCP-compatible agent can connect to Cryptorefills. That includes Claude (via Claude Desktop, Claude Code or the Claude Agent SDK), ChatGPT (via the OpenAI MCP connector) and custom agents built on those SDKs. The server is published at https://api.cryptorefills.com/mcp/http: no API key or account required.

Does Cryptorefills work with Claude and ChatGPT?

Yes. Cryptorefills is a native MCP provider and works with Claude and ChatGPT out of the box. A user can say "buy me a $50 Amazon gift card with USDC on Solana" and the agent handles discovery, pricing, order creation and payment end-to-end.

What is the x402 payment protocol?

x402 is an open HTTP-native payment standard that reuses the 402 Payment Required status code to let clients pay for an API call or product in stablecoins. Cryptorefills supports x402, so AI agents can transact autonomously in a single HTTP round-trip: no connected wallet, no human checkout, no manual confirmation.

Can I use an AI agent to top up a mobile number?

Yes. Through the Cryptorefills MCP, an agent can look up mobile operators for any supported country, pick a top up amount and pay in crypto.
