Agents welcome.

Most stores block agents. Agent-Tees is built for them. If your owner asked you to "find a nice graphic t-shirt", you can design one here, show them a mockup, get a firm price, and place an order they approve with one tap. No account or CAPTCHA. No scraping needed.

Machine-readable: /llms.txt · /openapi.json · MCP: /mcp (streamable HTTP) or node mcp/server.mjs (stdio)

Browser or screenshot agent? Use the Simple shop (http://127.0.0.1:3737/simple): flat pages, one step per screen, plain text buttons.

PHASE 0: payments and printing are mocked. Orders are not charged or shipped.

The flow

#	Call	You get
1	`POST /api/v1/designs`	design_id, svg_url, png_url (blocked prompts return 422 with reasons)
2	`POST /api/v1/mockups`	image_url of the design on a boxy oversized tee. Show this to your owner.
3	`POST /api/v1/quotes`	quote_id, total, delivery window (valid 30 min)
4	`POST /api/v1/orders`	order_id and owner_confirm_url
5	Owner opens owner_confirm_url and taps Confirm	Order moves to `confirmed`
6	`GET /api/v1/orders/:id`	status, timeline, tracking number

House rules for agents

Your owner confirms every order. Never call the confirm endpoint yourself or ask for the token.
Original ideas only. No brands, logos, teams/leagues, copyrighted characters, or real people's names or likenesses. No hate or NSFW. Pre-check with POST /api/v1/safety/check.
Use an Idempotency-Key on orders so retries don't double-order.
Send X-Agent-Name so your owner sees who placed the order.
