# Flight search, built for AI agents.

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

**100% free**

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

## Works where your agent works

- 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 use a consistent format that an agent can reason about.

### Token-efficient

Markdown removes visual noise so more useful flight context fits into the conversation.

### No new interface

Use standard Markdown, HTTP, or MCP instead of maintaining a client-specific integration.

## From prompt to flight options in three steps.

1. **Ask naturally** — Share the route, dates, cabin, and passengers in the conversation you already use.
2. **Search real flights** — Ulysse searches available fares and presents every option in one consistent structure.
3. **Compare clearly** — Let your agent summarize price, duration, stops, and trade-offs before you choose.

## One flight search. Three agent-native ways in.

### Markdown

Request clean Markdown directly. No navigation, scripts, or page chrome—only useful context for the agent.

```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 one URL. Use the full 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

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

## 100% free to search.

Use flight search from your agent without adding another subscription. Normal ticket prices and fare conditions still apply when you decide to book.

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

## Copy. Paste. Take off.

No SDK is required. Start by giving your agent a clear travel request and ask it to compare the trade-offs that matter to you.

```text
Use Ulysse Agents to find the best return flights from Paris to New York from September 12 to September 20 for one adult. Compare the three best options by total price, duration, and number of stops. Do not book anything without asking me first.
```

## Everything you need to let your agent take off

### Is Ulysse Agents really free?

Yes. Searching for flights through Ulysse Agents is free. The flights themselves keep their displayed price and applicable fare conditions.

### Which agents are supported?

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

### Why Markdown?

Markdown keeps the content structured while removing visual markup and scripts. That means fewer tokens, less noise, and more room for your request and the offers.

### What is MCP?

MCP, the Model Context Protocol, lets compatible agents use external tools in a standard way. Ulysse Agents can therefore stay directly inside your agent conversation.

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

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