Set Up My Payout Account

Create your PRIMARY payout account. REACHES A PAYMENT PROVIDER.

The first-time path, where POST /methods adds a second one. Your profile country picks the rail: a US person gets a Stripe Express account created at Stripe, everyone else a Wise method. Idempotent - a second call returns the account that already exists instead of opening another one at Stripe.

400 when your profile has no country (set it with PATCH /me/profile first). Refused for an agency-managed rep - their payout goes to the agency.
