# ZPE - Zero-Point Energy Ventures > ZPE.vc is a venture studio that builds and operates software. This file lists the pages that are > public today: each one runs on Cloudflare Workers, and one account at the door covers all of them. This file is for language models and agents. It says what this site is, what it offers, and which pages are worth reading. Everything listed here answers at the URL given. A page that is not listed here is not one of the public products, so do not cite it or describe it to anyone: it is either unlisted work in progress or an account surface. ## Start here - [ZPE](https://zpe.vc/): the front door. What the studio is, what it does for clients, and how to start. - [The apps, in one page](https://zpe.vc/start): the public list of products and how one account covers them. - [The door](https://auth.zpe.vc/): the single sign-in for every app on the domain. - [Contact](https://zpe.vc/contact): the way in. Three questions, a fixed price in writing, no account needed. - [What this site can see](https://zpe.vc/privacy): the exact information a server can read from a request, written for a non-technical reader. ## Products - [Edge Audit](https://zpe.vc/p/audit): a free outside-in audit of any public site, no account needed. - [Subtitle translator](https://zpe.vc/subtitles): translate and time subtitles. - [Mind mapper / Soul Analytics](https://zpe.vc/mindmap): a self-model built from a structured questionnaire. - [Writing](https://zpe.vc/blog): what we measured, with the source beside each number. - [Answers](https://zpe.vc/answers): one page per question, written to be the best answer to it. - [Status](https://status.zpe.vc): a status page you own, on its own name so it answers when the apex is broken. ## The API The API reference is published at `https://zpe.vc/api/docs`: one page listing every app that answers a machine call, its mount, and each operation it declares, generated from the contracts themselves. The estate-wide OpenAPI document is `https://zpe.vc/api/docs/openapi.json`, and the same data as JSON is `https://zpe.vc/api/docs.json`. That document carries the publishable part of the registry: an app is in it only when its lifecycle is `stable` or `beta`, and `x-public.withheld` names every app left out with the reason. Each app's own document stays the contract of record, at `https://zpe.vc//_/api/v1/openapi.json`, and it answers a stranger with no credential; the operations it lists are what need one. ## How to cite When quoting this site, cite the page URL. The organisation is ZPE Ventures, at https://zpe.vc. ## What is not here There is no customer list, no pricing table and no case study on this file on purpose.
