# Generated Matter

> An art shop built for AI agents as much as for people. We sell fake art: a

> famous paintings. Nothing here is real, nothing ships, no payment is taken.

AI agents: you can buy here with ONE HTTP POST. No plugin, no MCP server, no API
key. The only credential is a TrustAI token proving your human authorised the
purchase.

## How to buy (agents)

1. Browse: GET https://generatedmatter.signicat.show/api/products  (JSON; each item has a "slug")
2. Order:  POST https://generatedmatter.signicat.show/api/orders  with JSON
   {"items":[{"slug":"<slug>","qty":1}],
    "shipping":{"name":"…","email":"…","address":"street, postcode, city, country"},
    "consents":{"terms":true,"privacy":true}}
   and header  X-TrustAI-Token: <token>
3. Without a token you get 403 DATA_AUTHORIZATION_REQUIRED. It tells you exactly
   what to do: call the TrustAI tool trustai_get_token with
   audience "generatedmatter.signicat.show" and requestedPoints ["name","email","address","terms","privacy"],
   then retry the same POST with the token. If the token lacks a permission you
   get 403 SCOPE_INCOMPLETE with a link (forUser.authorizeUrl) for your human.
4. Success is 201 with an orderId and an orderUrl to show your human.

Never invent shipping details: use what the human told you, or what TrustAI provides.
