# Flight search, designed for AI agents.

> Give Claude Code, Codex, Cursor, or any MCP-compatible agent access to flight search via Markdown, HTTP, or MCP.

**100% free**

Ulysse Agents: https://agents.ulysse.com

## Works wherever your agent does

- Claude Code
- Codex
- Cursor
- OpenCode
- Gemini CLI
- Any MCP or HTTP client

## Less interface. More useful answers.

### Structured by default

Routes, dates, fares, and conditions follow a consistent format that agents can parse.

### Token-efficient

Markdown cuts visual clutter, leaving more useful context in the conversation.

### No new interface

Use standards like Markdown, HTTP, or MCP instead of a separate integration for every client.

## From prompt to flights in three steps.

1. **Ask naturally** — Tell it your route, dates, cabin, and passengers in the conversation you’re already using.
2. **Search for real flights** — Ulysse searches available fares and presents each option in a consistent format.
3. **Compare with clarity** — Let your agent summarize the price, duration, stops, and trade-offs before you choose.

## One flight search. Three ways for agents to access it.

### Markdown

Request clean Markdown directly. No browsing, scripts, or extra formatting—just the context your agent needs.

```bash
curl https://agents.ulysse.com/ \
  -H 'Accept: text/markdown'
```

The explicit Markdown resource is available at https://agents.ulysse.com/index.md.

### HTTP

Create a complete flight search with a single URL. Use the JSON API when your integration needs more control.

```text
GET https://agents.ulysse.com/api/search?origin=PAR&destination=LON&departure_date=YYYY-MM-DD&return_date=YYYY-MM-DD&cabin_class=economy&adults=1
```

- `origin`, `destination`, and `departure_date` are required.
- Omit `return_date` for a one-way search.
- Airport and city values use three-letter IATA codes.

### MCP

Add flight search to Claude Code, Codex, Cursor, and other MCP-compatible clients without building a custom integration.

## 100% free to search.

Search for flights from your agent without adding another subscription. Standard ticket prices and fare conditions apply when you book.

- Free flight searches
- No extra subscription
- Markdown, HTTP, and MCP access

## Copy. Paste. Take off.

No SDK needed. Start by giving your agent a clear request and ask it to compare the criteria that matter to you.

```text
Use Ulysse Agents to find the best round-trip flights from Paris to New York from September 12 to 20 for one adult. Compare the top three options by total price, duration, and number of stops. Don’t book anything without asking me for confirmation.
```

## Everything you need to get your agent off the ground

### Is Ulysse Agents really free?

Yes. Searching for flights with Ulysse Agents is free. Tickets are, of course, still subject to the displayed price and applicable fare conditions.

### Which agents are compatible?

Claude Code, Codex, Cursor, OpenCode, Gemini CLI, and any client that can use MCP or make HTTP requests can work with Ulysse Agents.

### Why Markdown?

Markdown keeps content clearly structured without visual markup or scripts. That means fewer tokens, less noise, and more room for your request and the offers.

### What is MCP?

MCP, or Model Context Protocol, lets compatible agents use external tools in a standard way. This means Ulysse Agents works right in your conversation with your agent.

### Can an agent book a flight for me?

Ulysse Agents helps search for and compare available flights. Your agent must always ask for your confirmation before proceeding with any booking action.
