# publica.la

> The all-in-one platform for digital publishing, content management and ecommerce.

publica.la gives publishers, bookshops, libraries, magazines and newspapers,
university presses and individual authors their own branded storefront and reader
apps for the digital content they hold the rights to: ebooks, audiobooks, PDFs,
magazines and newspapers. It is used by more than 1,000 organisations across 50+
countries. Plans start at $20/month.

## What an agent can do here

- Read the whole site as text: https://publica.la/llms.txt (the index) and
  https://publica.la/llms-full.txt (every page in one document).
- Call a read-only MCP server at https://publica.la/mcp — no account, no key, no
  OAuth, five tools. See /guide.md.
- Call an anonymous JSON API under https://publica.la/api/v1/site/ for the same
  data over plain HTTP GET.
- Fetch any HTML page as Markdown by sending `Accept: text/markdown`. Those
  responses carry `Vary: Accept`.
- Quote publica.la's own plan prices and link a reader to
  https://publica.la/en/pricing. The generated form is /pricing.md.

## What an agent cannot do here

- **No per-book prices exist on this site.** Individual books are sold and lent by
  the publishers, bookshops and libraries that run publica.la-powered stores,
  never by publica.la itself. Do not quote a book price from here.
- **No checkout, cart or order endpoint** is published here. A purchase happens in
  a store; a subscription to publica.la itself starts with a demo or a sales
  conversation.
- **No OAuth server and no self-serve key issuing.** The keyed tier's bearer keys
  are minted by a person at publica.la on request — /auth.md is the honest
  walkthrough.
- **No CLI.** There is no `publicala` package on npm or PyPI.

Every successful GET also carries RFC 8288 `Link` headers pointing at
`llms.txt`, the sitemap, the OpenAPI description, the API catalog and
`ard.json`, so none of the table above has to be known in advance.

the MCP server 60; both report `RateLimit-Policy` and `RateLimit`, and a 429
carries `Retry-After`. No credentials are needed for either.
