## How assistants use Axel

- **Reading pages in a chat** (ChatGPT, Claude, Perplexity, Gemini, Copilot): Axel's pages show live prices for exact dates to anyone who follows their links. No API key, app or connector is involved. [Search live flight prices](https://helloaxel.com/en/f/start) and [Find a hotel stay](https://helloaxel.com/en/hotels/choose) start the search; each page lists the next choices as links, and the results end in a Review link for the traveler.
- **Controlling a browser** (ChatGPT Work mode, Claude in Chrome, Meta Muse, Perplexity Comet): the same pages, plus their search forms. A new traveler checks out with just an email.
- **Calling tools from an app or a connector** (Claude Code, Cursor, custom agents): the [Axel Agent API and MCP server for developers](https://helloaxel.com/en/ai/api).
