Mercari

Destination guide. Vault acts only on your own authenticated session, and only where a transport is shipped.

Reselling catalog management and bulk listing tools for Mercari.

📦 Mercari Browser Agent (coming soon, Seller and above): When released, publishing runs on your own authenticated Mercari session, one item at a time — a job is only reported published after Mercari's own listing state verifies.

📦 Mercari Import Workflow: Mercari's official web import tool pulls listings from eBay, Poshmark, and Depop. Beams Vault prepares eBay-ready or Poshmark-ready catalog files for that import (this is Mercari's own external-store import, not a bulk CSV upload by Vault).

Log-ins, checkpoints, or captchas are never solved by Vault: the job stops truthfully and the tab stays open for you to finish.

There is no completion-time promise: the queue works while your extension is running, and batch selections publish one listing at a time.
