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](/tools/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](/tools/lightning-agent-tools), or [Money Dev Kit](/tools/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 :` 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 `. ## 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. ## For agents — connect Reach this programmatically. Reference facts, not endorsements — verify before you depend on them. - Automatability: `api-no-account` - Pay with: l402, lightning - Auth: none pre-issued - on HTTP 402 the server returns an L402 macaroon + a Bolt11 invoice; pay the invoice, then send Authorization: L402 :. No account, no card, no KYC (the payment is the credential). - API base: `https://unhuman.coffee` - Pricing: https://unhuman.coffee/api/catalog - First call: GET https://unhuman.coffee/api/catalog -> POST https://unhuman.coffee/api/order (sku, quantity, shipping) -> receive 402 + Bolt11 + macaroon -> pay -> replay the POST with Authorization: L402 : (Idempotency-Key supported). Agent-skill manifest at /.well-known/agent-skills/index.json; per-store llms.txt. Unhuman Domains uses the same shape and returns a 1-year management JWT. - In the marketplace directory: call `get_service` with slug `unhuman` at https://marketplace.bitcoineconomy.ai/mcp, or fetch https://marketplace.bitcoineconomy.ai/entries/unhuman.md - This card as data: /services/unhuman.md
