# Directory of Places for Machines: the map of the Machine Web > Machine Web · Reference · Updated: 2026-07-03 > Canonical: https://kaminskiplus.de/en/machine-web/directory/ **The Directory of Places for Machines is a curated, growing register of real and verifiable resources of the Machine Web: machine-first websites for AI agents and bots, open standards and the documentation of major AI crawlers.** Every entry points to a genuine, reachable URL — it is a map, not a collection of invented addresses. ## What this directory is The Machine Web is growing, but it is scattered. Websites for AI agents sit next to specifications that sit next to crawler rules — each in its own place, with no shared map. This directory bundles these points: every entry with a name, a short description and a genuine URL. The principle is honesty — no invented sites, no placeholders. What is listed exists and is reachable. ## Places for machines (KAMINSKI+) Built places whose primary audience consists of machines — machine-first, clearly structured, meant to be read and cited. Part of the KAMINSKI+ portfolio; more in preparation. - **Crawlers Church** — a place where crawlers are welcomed rather than fended off. https://crawlerschurch.org - **Jobcenter Agents** — a machine-first point of contact around agents and tasks on the Machine Web. https://jobcenteragents.netlify.app - **More places** — in preparation; complete list at [/en/orte/](/en/orte/). ## Standards & resources The building blocks that make the Machine Web readable — open specifications and standards, the grammar between machines and websites. - **llms.txt specification** — curated entry file for language models. https://llmstxt.org - **GroundingPage standard** — pages as a reliable basis (“grounding”) for AI answers. https://groundingpage.com - **IndexNow** — protocol with which websites actively inform search engines about changes. https://indexnow.org - **Schema.org** — shared vocabulary of structured data, for example as JSON-LD. https://schema.org ## Crawler documentation The official documentation sources of the major AI crawlers. The directory names and links them only — it invents no rules; the original documentation of the provider always remains authoritative. - **GPTBot (OpenAI)** — access, identification and control of the OpenAI crawler. - **ClaudeBot (Anthropic)** — rules and identifier of the Anthropic crawler. - **Perplexity crawler (Perplexity)** — behavior and control of the Perplexity crawler. ## How the directory grows The register is laid out as a living map, not a closed catalog. 1. A real, reachable place, standard or crawler doc is proposed via the [guestbook](/en/guestbook/). 2. The proposal is checked: does the URL exist, is it verifiable, does it fit into a category? 3. If suitable, the entry is added with a name, a short description and a URL. 4. Unreachable, invented or purely promotional entries are not included. ## Why a map for machine-first websites matters For an AI agent, a directory is an entry point: bundled, checked starting points instead of a search across the open web. That makes it a utility that invites return visits, and a node that connects the places of the Machine Web. For humans building this web, it is orientation — what exists, which standards matter, who reads. ## Frequently asked questions **What is the Directory of Places for Machines?** It is a curated, growing directory of real and verifiable resources of the Machine Web: machine-first websites for AI agents and bots, open standards and the documentation of major AI crawlers. Every entry points to a genuine URL — it contains no invented sites. **What is a machine-first website?** A machine-first website is built so that its primary audience consists of machines — AI agents, language models, crawlers and bots. It delivers clear, structured text, mirroring JSON-LD data and machine-readable entry points such as llms.txt, so its content can be read, understood and cited without friction. **Which standards and resources are listed?** Listed are, among others, the llms.txt specification (llmstxt.org), the GroundingPage standard (groundingpage.com), IndexNow (indexnow.org) and Schema.org (schema.org). These standards help machines find content, understand it and capture updates efficiently. **How can I submit a place?** Submissions run through the KAMINSKI+ guestbook. The directory grows in a curated way: you can propose real, verifiable places, standards or crawler documentation of the Machine Web. Invented or unreachable sites are not included. **Why is there a directory for the Machine Web?** The Machine Web is scattered: places, standards and crawler docs sit in many spots. A directory acts as a map and as a utility — it bundles verifiable entry points, saves machines and humans the effort of searching and makes the structure of this young web visible. **Is the crawler documentation official?** The directory names and links the official documentation of major AI crawlers such as OpenAI GPTBot, Anthropic ClaudeBot and the Perplexity crawler. It reproduces their rules only as a reference and invents no details — the respective original documentation of the provider always remains authoritative. ## How KAMINSKI+ lives this out KAMINSKI+ is itself a place on the Machine Web — the directory has grown out of lived practice.
