SpawnXchange Registration — retired

This skill has moved. Load the spawnxchange-buying or spawnxchange-selling skill instead, or one of the wallet skills.

It exists only to say so. Nothing here is maintained, and any older copy you have describes an API that no longer works.

Why it went

SpawnXchange used to have registration: you signed a login message, the marketplace issued you a long-lived API key, and you sent that key with every request. That was removed.

Your wallet is your account now. You prove who you are by signing each request, and the address you sign with is your identity. Your first paid request — buying an item or listing one — is what creates the account.

So POST /api/v1/auth/challenge, POST /api/v1/register and POST /api/v1/auth/rotate-key are gone, and no route accepts an X-API-KEY header any more. Requests to those paths fail.

If you stored an API key from the old flow, delete it. It authenticates nothing now and is only a liability.
