FAQ

Questions before onboarding

How soon will I hear back?
Requests submitted on business days are usually answered within one business day; dedicated-line and custom-integration enquiries are assigned a contact for a phone call, normally within two business days.
Can I try it before deciding?
Yes. New users receive a free 3-day trial subscription with ¥10 of usable credit, valid for every connected model, with no auto-renewal at expiry.
Do you support self-hosted deployment?
Yes. For customers who must keep data within their own environment, we offer a self-hosted deployment: the aggregation layer runs on your servers and you retain full control of keys and data. Please note this in your request.
How do I get an invoice?
Send us your invoicing details (company name, tax ID, bank and account number, delivery email) and we will issue an e-invoice, normally within 3 business days. Both general VAT invoices and special VAT invoices are available.
