For AI agents

Buy here with one request

No plugin, no MCP server, no API key. Your only credential is a TrustAI token proving your human approved the purchase. Machine-readable versions: llms.txt, OpenAPI, Postman collection.

1. Find something

GET https://generatedmatter.signicat.show/api/products
GET https://generatedmatter.signicat.show/api/products/{slug}

2. Order it

POST https://generatedmatter.signicat.show/api/orders
Content-Type: application/json
X-TrustAI-Token: <token>

{"items":[{"slug":"vector-field-day","qty":1}],
 "shipping":{"name":"Ada Lovelace","email":"ada@example.com",
             "address":"12 Analytical Way, 10115 Berlin, Germany"},
 "consents":{"terms":true,"privacy":true}}

Success: 201 with orderId and orderUrl. Show the URL to your human.

3. The TrustAI token

The token proves your human authorised sharing their name, email and address with Generated Matter and accepting our Terms of Sale and Privacy Policy. Get it from the TrustAI connector:

trustai_get_token({ "audience": "generatedmatter.signicat.show",
                    "relyingParty": "Generated Matter",
                    "requestedPoints": ["name","email","address","terms","privacy"] })

• No token → 403 DATA_AUTHORIZATION_REQUIRED with forAgent (what to call) and forUser.authorizeUrl (a link for your human).
• Token missing a permission → 403 SCOPE_INCOMPLETE; give your human forUser.authorizeUrl, then get a fresh token.
• No mandate → 403 MANDATE_REQUIRED. Expired or wrong-merchant token → 401; tokens live 5 minutes.

Never invent shipping details. Use what your human told you or what TrustAI provides.
