# POST /recordMarketplaceRemix

> Increment a marketplace listing's public remix count. Called automatically when a listing is remixed. No authentication required.

<Note>
  You almost never call this directly — [`slideless remix <slug>`](/cli/commands#slideless-remix-slug-path) records the remix for you after downloading the files. Call it only when you build a custom remix flow on top of the public API.
</Note>

## When to use

Bump the public **remix count** of a [marketplace](/concepts/marketplace) listing. The CLI's `slideless remix` invokes this after it has written the listing's files locally, so the counter reflects real remixes. The endpoint records a usage signal only — it does not perform or return any file content.

This endpoint is **public** — no API key required.

## Endpoint

```
POST https://europe-west1-slideless-ai.cloudfunctions.net/recordMarketplaceRemix

## Auth

None. Do not send an `Authorization` header.
