# Developers & API — Bookworthy

Bookworthy exposes a small, agent-friendly read-only API. Responses are
JSON, CORS-open, cached, with frozen response contracts (URLs and shapes
are additive-only once shipped).

## Endpoints

- `GET https://bookworthy.com/api/facts` — the canonical fact base (what Bookworthy is, key facts, how it works).
- `GET https://bookworthy.com/api/v1/specs` — the live print specs (trim sizes, text/cover stocks) the Add-a-Book form uses.
- `GET https://bookworthy.com/api/v1/quote?binding=&trim=&paper=&cover=&pages=&qty=&country=` — validate a book spec and get an indicative price, including spine math.

The authenticated publish endpoints and an MCP server are designed but not
yet built. See the on-page reference for parameters and examples.
