## Run it

Ask an AI agent connected to Reduck over MCP (`https://mcp.reduck.ai/mcp`) to run `reduck/leboncoin.fr/create_ad`, or run it from a terminal:

```bash
npx @reduck-ai/cli@latest run --script reduck/leboncoin.fr/create_ad
```

## Input

- `price` (number, required): Asking price in euros.
- `title` (string, required): Ad title. leboncoin derives the category suggestions from this, so it must describe the item (e.g. "Vélo de ville adulte").
- `lastName` (string, required): Seller last name, required by the form.
- `location` (string, required): Street address to advertise from, e.g. "12 rue Duphot Paris". Resolved against leboncoin's own address suggestions; the first suggestion is taken and returned in resolvedLocation.
- `firstName` (string, required): Seller first name, required by the form.
- `description` (string, required): Ad body text.
- `imageBase64` (string, required): The ad photo as base64 (PNG or JPEG), without a data: prefix. leboncoin refuses to publish an ad with no photo.
- `dryRun` (boolean, optional): True (default) fills the entire form and stops on the boost step without publishing. Set false to actually publish, which takes the free option only.

## Output

- `title` (string, required)
- `dryRun` (boolean, required)
- `published` (boolean, required): True only when the confirmation screen was reached. False on a dry run.
- `categoryChosen` (string, required): The category leboncoin suggested for this title and the script selected.
- `resolvedLocation` (string, required): The address as leboncoin resolved it from its own suggestions, e.g. "12 Rue Duphot, Paris (75001)".
- `price` (number | null, optional)
- `confirmationText` (string | null, optional): The confirmation screen's message when published; null on a dry run. A newly posted ad sits at "En cours de vérification" until leboncoin reviews it.
