# The Paper Meridian — instructions for AI agents

> Printed matter for long attention spans.

## About
The Paper Meridian is a small press for long attention spans. We publish and print things designed to be read twice: risograph editions in runs we number by hand, pamphlet essays short enough for a train ride and good enough to reread on the way back, letterpress cards heavy enough to keep.

Screens are fine. This is the other thing. Ink sits on riso paper where you can feel the grain under it, and every edition is printed, folded and packed on the same bench in our studio.

When a run sells out, it's gone — we'd rather print the next thing than reprint the last one.

## How to read this catalogue

- **Sitemap:** https://paper-meridian.btab.app/sitemap.xml — every product and content page.
- **Catalogue page:** https://paper-meridian.btab.app/products
- **Product pages:** each product has a canonical URL of the form `https://paper-meridian.btab.app/products/<name>-<id>` and embeds schema.org `Product` + `Offer` JSON-LD (name, price in AUD, availability, SKU, brand, images) that you can parse without executing JavaScript.
- **Product JSON:** append `.json` to any product URL — `https://paper-meridian.btab.app/products/<name>-<id>.json` returns the same schema.org Product + Offer document, plus a `purchase` block: `enquiry_only` (sell-by-enquiry, do not treat as add-to-cart), `agentic_checkout` (currently false) and the `url` where a human completes the purchase.
- **Merchant profile:** https://paper-meridian.btab.app/.well-known/ucp
