Store-scoped API key with invoices:write scope (default for developer keys)

  -H "Authorization: Bearer sk_live_EXAMPLE_DO_NOT_USE" \
  -H "Content-Type: application/json" \
  -d '{

    "amount": "10.00",
    "currency": "USD",
    "return_url": "https://example.com/thank-you"
  }'

Open the checkout_url from the response (e.g. https://pay.meum.io/inv_a1b2c3d4…)
Select a payment token and enter a refund address
Complete the on-chain payment (or use dev simulation if available in your environment)
Poll status or wait for webhook:

curl https://api.meum.io/v1/invoices/inv_a1b2c3d4…/status \
  -H "Authorization: Bearer sk_live_EXAMPLE_DO_NOT_USE"

Expected result
