# Remove a Product Hunt launch upvote

Automatically remove a Product Hunt launch upvote on producthunt.com. Withdraw the signed-in account's upvote from a Product Hunt launch. This is the inverse of upvoting one, and it is written the same careful way: because Product Hunt's vote control is a toggle, the script first checks whether an upvote actually exists and does nothing if it does not, instead of pressing the control and accidentally adding one. The result reports the account used, whether there was no vote to remove, the score afterwards, and confirmation read back from Product Hunt's own response rather than from the button. Accepts a full launch URL or a "product/launch" slug pair.

## Run it

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

```bash
npx @reduck-ai/cli@latest run --script reduck/producthunt.com/remove_launch_upvote
```

## Input

- `launch` (string, required): Full launch URL (e.g. "https://www.producthunt.com/products/notion/launches/notion-mail") or a "product/launch" slug pair (e.g. "notion/notion-mail").

## Output

- `hasVoted` (boolean, required): Whether the account still holds an upvote after the run. False on success.
- `launchUrl` (string, required)
- `account_used` (string, required): Handle of the account whose vote was withdrawn, read from the signed-in session rather than assumed.
- `already_absent` (boolean, required): True when this account held no upvote on the launch, so nothing was pressed.
- `verified_on_page` (boolean, required): True when Product Hunt's own response confirmed the launch is no longer upvoted.
- `postId` (string | null, optional): Product Hunt's numeric id for the launch.
- `scoreAfter` (number | null, optional): Score Product Hunt reported with the change. Other people vote continuously, so this is their number at that instant, not necessarily scoreBefore - 1.
- `scoreBefore` (number | null, optional): Score shown on the control before the change. Read from the rendered figure, so it can lag other people's votes by moments.
