Six steps, about fifteen minutes, and one thing you have to bring: an Anthropic API key. Read step 2 before you sign up — it is the only step that costs money and the only one that can’t be done from inside the app.
Flipwright deployments aren’t open to the public — you need a code from whoever runs this one. It looks like ABCD-EFGH-JKMN-PQRS, works once, and usually expires in two weeks. Case and dashes don’t matter when you type it.
If the code was issued for a particular email address, sign up with that address — it won’t work with another one.
This is the one thing you have to bring yourself. The key pays for reading your photos and writing your listings. It’s yours, billed to you, and it is not optional — without one the app can look at your sales but cannot make a listing.
sk-ant- and is shown once.Rough cost: a few cents per item, depending on how many photos you give it. Twenty items is small change; it is not a subscription and there is no minimum.
Go to the sign-in page, choose Create an account, and enter your email, your invite code and a password. Twelve characters minimum — length beats punctuation, so a passphrase you can actually remember is stronger than a short word with a symbol jammed in it.
Then confirm your email. A link arrives within a minute or so. Until you click it the account can sign in and look around but cannot reach Claude or eBay — those cost money, so they wait for a confirmed address. Settings can send the link again.
Settings → Anthropic API key. Paste, save. It’s encrypted at rest and never comes back out of the server — the card shows only its last four characters, so you can tell which key is loaded without it being readable.
On the posting page, hit Connect eBay. You’ll be sent to eBay to sign in and approve; you come back connected. Nothing is posted without you pressing post.
Two of the permissions are optional and worth taking: Money ledger lets the app see charges that aren’t attached to a sale — store subscription, promoted listings, shipping labels — which on a quiet month can be several times the per-order fees. Traffic reports adds views and impressions to the seller view.
Photograph one item — four or five angles, including any label or damage. Drop the photos in. The app writes a title, a description and item specifics, estimates a price from what similar things are asking, and works out postage from the weight and box it guesses.
Read it before you post. It is a draft written by a machine that has seen your photos and nothing else — it does not know the thing is scratched underneath, or that it’s the rare version. Fix the title, correct the price, then post.
