## What It Does

`save_to_launch_list` saves one market or one product to your Launch List. The Launch List is your shortlist of ideas to work on in Launch Fast. If you save an item two times, nothing changes.

The Launch List holds up to 500 markets and 500 products. To remove items, use the Launch Fast web app.

## When To Use It

Use `save_to_launch_list` when you find a market or product that you want to keep. The product must be in the Launch Fast catalog. To add a product that is not in the catalog, use [`research_product`](https://docs.launchfastlegacyx.com/mcp/research/research-product) first.

## Inputs

Give `market` or `asin`. Do not give both.

| Input    | Required                  | Values                            | Example             |
| -------- | ------------------------- | --------------------------------- | ------------------- |
| `market` | One of `market` or `asin` | A market slug or name             | `silicone-spatulas` |
| `asin`   | One of `market` or `asin` | An Amazon US ASIN or product link | `B0C1EXAMPL`        |

## What The Answer Contains

* The saved market (name and slug) or product (ASIN).
* The status: `added` or `already saved`.
* When the item is added, a link to your Launch List.
* The next call: `get_market` for a market, or `get_product` for a product.

## Example Prompts

```text
Save the silicone spatulas market to my Launch List.
```

```text
Add B0C1EXAMPL to my Launch List.
```

## Common Errors

| Error           | What it means                                                                                                                       | What to do                                                                                                                                             |
| --------------- | ----------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------ |
| `not_found`     | The market does not exist, or the product is not in the Launch Fast catalog.                                                        | For a product, run [`research_product`](https://docs.launchfastlegacyx.com/mcp/research/research-product) first. For a market, search with [`find_markets`](https://docs.launchfastlegacyx.com/mcp/research/find-markets). |
| `cap_reached`   | Your Launch List holds 500 items of that kind.                                                                                      | Remove some items in Launch Fast, then save again.                                                                                                     |
| `still_running` | The market is still being researched.                                                                                               | Check it with [`get_job`](https://docs.launchfastlegacyx.com/mcp/research/get-job), then save again when it is done.                                                                     |
| `invalid_input` | The call gave both `market` and `asin`, or neither, the ASIN is not a 10-character ASIN, or `market` is longer than 120 characters. | Give one of the two, with a market slug or name of up to 120 characters or a 10-character ASIN.                                                        |
| `plan_required` | Your plan does not include the Launch List.                                                                                         | Check your plan on the [usage page](https://launchfastlegacyx.com/settings/usage).                                                                     |
