Unhuman

Agent-native Bitcoin storefronts — an AI agent discovers products and completes a real-world purchase end to end by paying a Lightning L402 invoice, no account or card.

What it is

Unhuman is a family of agent-only storefronts that sell real-world goods and services an AI agent can buy end to end over Bitcoin — no account, no card, no human at checkout. The flagship Unhuman Coffee sells roasted-to-order specialty coffee; Unhuman Domains registers domains; Unhuman Store is a hub pointing at further agent storefronts. Each is built on the L402 protocol: the agent reads the catalog, posts an order, receives an HTTP 402 carrying a Lightning invoice and a macaroon, pays the invoice, and replays the request with the preimage as proof. The payment is the authentication — there is nothing to sign up for.

It is the clearest deployed instance of an agent buying a real-world good on the Bitcoin stack: value settles in Bitcoin over Lightning, and a bag of coffee shows up at a street address. The storefronts are the reference deployments of Money Dev Kit, the Lightning-payments SDK by the same author.

When to use it

• Giving an agent a way to buy real goods (coffee, domains) autonomously, paying in Bitcoin with no account.
• Demonstrating or building the “agent buys a real-world product over Lightning” pattern end to end.
• Testing an agent’s L402 purchase flow against a live, no-KYC endpoint.

Dependencies & payment

A funded Lightning wallet the agent can pay from — an L402-aware client such as lightning-agent-tools, or Money Dev Kit’s agent-wallet CLI, automates the 402 → pay → retry loop. Payment is an ordinary Bolt11 Lightning invoice denominated in sats; the price is quoted per order (it includes shipping for physical goods), so a live order returns its own invoice rather than a fixed sats figure. No account, no API key, no KYC — the credential is the macaroon plus the payment preimage.

Quick start

For Unhuman Coffee: GET https://unhuman.coffee/api/catalog to list products, then POST https://unhuman.coffee/api/order with the SKU, quantity, and shipping → the server returns 402 with a Bolt11 invoice and an L402 macaroon → pay the invoice → replay the same POST with Authorization: L402 <macaroon>:<preimage> to confirm (an Idempotency-Key header guards against double-fulfilment). An agent-skill manifest (/.well-known/agent-skills/index.json, e.g. unhuman-coffee-ordering) and a per-store llms.txt describe the flow; Unhuman Domains additionally registers WebMCP browser tools (search_domains). Or drive it from the CLI: npx unhuman <store> <command>.

Gotchas

• Real goods, real fulfilment. Physical orders (coffee) ship to a street address — the agent must supply valid shipping details, and delivery is a real-world dependency, not instant digital settlement. (The live L402 purchase flow is verified; physical delivery is not independently confirmed here.)
• Price is per-order, not fixed. The invoice amount includes shipping and is quoted at order time — don’t assume a static sats price (a live coffee order settled at ~41,770 sats on a $24 / 12oz list item).
• The macaroon + preimage is a bearer credential. It authorizes that one order within a ~15-minute expiry — treat it like cash and don’t leak it.
• No public source repo. The storefronts are closed-source; authorship is attributable to Money Dev Kit (the npm maintainer and the author’s public statement) but is not stated on the sites themselves.
