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. There is no checkout UI and no form filling. The agent receives the delivery code or voucher automatically once the on-chain payment is confirmed.

Which AI agents support Cryptorefills MCP?

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

Does Cryptorefills work with Claude and ChatGPT?

Yes. Cryptorefills is a native MCP provider and works out of the box with Claude and ChatGPT. A user can simply 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. Just ask the agent to "top up +1234567890 with $20 in USDT" and it will handle carrier detection, pricing and payment without leaving the chat.

Agent skills on GitHub

Skills included

Where a traditional API requires your code to call endpoints directly, MCP lets an AI agent call them on your behalf: same catalog, same checkout, less glue code. Running npx skills add cryptorefills/agents installs three skills that share one MCP connection. Each skill targets a different use case.

MCP manifest discovery (.well-known/mcp.json)

Cryptorefills publishes a machine-readable MCP manifest at cryptorefills.com/.well-known/mcp.json. This lets MCP-compatible clients auto-discover the server, tools, workflows, and prompts without custom glue code.

What this enables

Server endpoint discovery via https://api.cryptorefills.com/mcp/http.
HTTP transport for streamable MCP sessions, not only stdio.
Built-in workflows and prompts for conversational purchase journeys.
A no-curl path where AI tools can call Cryptorefills APIs natively.

Exposed MCP tools

purchaseElicitation interactive wizard flow.
searchProducts free-text search by brand, country, or category.
listBrands, listProductsForCountry, getProductPrice for catalog and pricing.
getCurrencies and getPaymentViasWithCurrencies for payment rails.
validateOrder, createOrder, and getOrderStatus for full order lifecycle.

Workflows

purchase_gift_card_or_mobile_topup: complete purchase flow from search to delivery.
browse_catalog: browse products without purchasing.
interactive_purchase: step-by-step guided elicitation for agents with limited context.
prompted_gift_card_purchase: natural-language prompt-driven purchasing.

Prompts

purchaseGiftCard: guides an AI agent through a gift card purchase using structured or natural-language parameters.

Example Claude MCP config (claude_desktop_config.json)

{
  "mcpServers": {
    "cryptorefills": {
      "url": "https://api.cryptorefills.com/mcp/http",
      "transport": "http",
      "headers": {
        "User-Agent": "Cryptorefills-MCP/1.0"
      }
    }
  }
}

Automation scenarios for Web3 user agents

Wallet marketplace bot: user picks brand, bot quotes USDC, executes, then streams status.
Telegram mini app assistant: conversational purchase flow with validation guardrails.
Rewards agent: convert on-chain points into real-world spend with policy checks.
Treasury spend helper: controlled, auditable gift card procurement with stablecoins.

Implementing with OpenClaw

With openclaw.ai use tool-based orchestration with deterministic step boundaries and explicit failure handling.

Resolve allowed rails first from /v3/payment_vias (for example prefer USDC on Solana).
Load catalog and constraints via /v2/brands + /v5/products/country.
Quote price just-in-time with /v4/products/price.
Run /v5/orders/validations before /v5/orders.
Track post-create state using stream first, polling fallback only when needed.
Expose clear delivery responsibility and email validity checks in the agent UX.
