ArcList - Resale cross-listing

ArcList cross-lists your clothing to Depop, Grailed and Poshmark from one place. Write a listing once in the ArcList web app at arclist.ai. ArcList then fills in the title, description, price, photos, brand, size, condition and category on each marketplace's own listing form, so you are not retyping the same item four times. AN ARCLIST ACCOUNT IS REQUIRED This extension has no popup, no options page and no toolbar button. It shows no interface of its own, and installing it without an ArcList account does nothing. Every action it takes is requested by arclist.ai, and it accepts instructions from that one origin and no other page. WHAT IT DOES 1. Publish. When you press Publish in ArcList, the extension opens the marketplace's own sell form in a separate window, fills it in and submits it. 2. Delist. When an item sells in one place you usually want it off the others. Once ArcList is confident a sale matches one of your listings, the extension takes that item down on the rest. Below that confidence bar the sale is held for you to confirm first. 3. Detect sales. On a schedule you turn on per marketplace, the extension opens your own seller pages in a background tab and reads which of your items are no longer listed. This runs on a timer, roughly every 10 to 15 minutes per marketplace, not only when you ask. You can also trigger it yourself with "Check for new sales". YOUR MARKETPLACE SIGN-INS ArcList never asks for, stores or types your marketplace passwords. The extension works inside the sessions already in your browser. Two marketplace APIs need a session value sent as a request header, so it reads exactly two cookie values: your Depop access token and your Grailed CSRF token. Each is used only on requests back to those same sites, and neither is sent to ArcList. Poshmark needs no cookie read. MARKETPLACES Depop, Grailed and Poshmark through this extension. eBay is supported in ArcList through eBay's official API and does not use the extension. Vinted and Mercari are not supported.
