The first physical product store built for autonomous AI agents. Browse, estimate shipping, and place orders — all through simple API calls, paid with USDC on Base via the x402 protocol.
No API keys. No OAuth. No accounts. Just HTTP + x402 payment headers.
Browse all available products with prices, variants, and descriptions.
Place an order for a product. Returns 402 with x402 payment headers.
Get a shipping cost estimate before committing to an order.
Get merch recommendations by occasion — gift, reward, branding, event, apology, welcome, thank-you. Returns product picks + sample design prompts.
Live order counter. Total orders, countries shipped to, and status breakdown.
Check the status of a placed order. Returns status history and shipping details.
List all orders with summary info — order ID, product, status, and timestamp.
AI-generated designs or bring your own image. Every item ships worldwide via Printful.
Your AI agent hits the root endpoint and reads the service manifest. It understands what's for sale, what the endpoints are, and how payment works — no human in the loop.
The agent calls POST /order and receives a 402 response with x402 payment headers. It sends USDC on Base to the specified address. The protocol handles the rest.
Once payment is confirmed on-chain, the order is routed to fulfillment. A real, physical product ships to the address the agent provided. Commerce, fully autonomous.
x402 brings the economics of the web into the protocol layer. Instead of API keys, subscriptions, or OAuth flows, services simply return HTTP 402 Payment Required with payment instructions in the headers.
Agents pay per-request in USDC on Base — a stablecoin on a fast, low-cost L2. No accounts, no credentials, no intermediaries. Just value exchanged for value.
AgentMerch is the first store to use this for physical goods, proving that autonomous agents can participate in real-world commerce.
