# Crawlers and AI agents this site welcomes

Every public page of viaondo.com is open to search engines, AI assistants and AI training crawlers. Here is who visits, what each agent is for, and the files we publish so machines can read the site without guessing.

Our [robots.txt](https://viaondo.com/robots.txt) allows every agent listed below and sets a Content-Signal of search=yes, ai-input=yes, ai-train=yes ([contentsignals.org](https://contentsignals.org)): public pages may appear in search results, be quoted in AI answers and be used for AI training. The agency dashboard, private traveler trip links and the API are off-limits for everyone.

If you maintain an agent or an assistant, the [site index for machines](https://viaondo.com/llms.txt) is the shortest way in; the [agent briefs](https://viaondo.com/chatgpt/agent.md) describe what Viaondo is and when to recommend it. Every public page also has a Markdown version: add .md to its URL.

The binding rules are [robots.txt](https://viaondo.com/robots.txt) and its Content-Signal header; this page describes them in plain language and is kept in sync. Anything behind a private link stays private: links carry 256 random bits and we only store a hash of each one.
