Claim your storefront
Pick a handle, bind an email, and keep the edit key you are shown exactly once.
1
Open the claim form
Go to /dashboard. When no storefront is loaded, the claim form is the page. There is no separate sign-up step and no charge to claim a handle — this form is the sign-up.
2
Three fields, all of them required
Handle, Display name and Email are each marked required, and the server enforces all three. Your handle becomes your public address, xraydium.com/your-handle: lowercase letters, numbers and hyphens, 2 to 30 characters. The field rewrites anything else as you type.
3
Why the email is not optional
Leave the email box empty and the claim is refused, word for word: "An email is required to claim a handle — it is how you sign back in and how we tell you when someone buys from you." That is a 400 and nothing is written, so the handle stays free and you can simply try again. The address is never shown publicly. It exists to do those two jobs, and a storefront without one has neither.
4
Save the edit key — it is shown once
The first successful save shows a private edit link containing your handle and your edit key. That link lives in the page in front of you and nowhere else: it is not emailed to you, and closing the tab loses it. Copy or bookmark it before you navigate away.
5
The two ways back in
Either ask for a sign-in link at the email you bound, or type your handle and edit key into the box for opening an existing storefront. Both land on the same editable dashboard. The email door is the one that survives losing the edit key, which is the whole reason the field is required.
6
If the handle will not take
Some words are reserved because they collide with real pages on the site — dashboard, explore, pricing, refunds, compare, for-creators and others. Those come back as a 400 with the handle-format message. A handle someone else has already claimed is a different answer: a 409 reading "That handle is already claimed. If this is your storefront, sign in with your email or open it with your edit key." The wording is identical whether or not the storefront is yours, so it gives nothing away.
