docker tag <your-image> cr.dtz.rocks/<image-name>:<tag>
docker push cr.dtz.rocks/<image-name>:<tag>
Can I scale my container automatically?

DowntoZero Cloud offers built-in monitoring for: • Power consumption • CPU usage • Logs for debugging

All of these are accessible via the dashboard for each deployment.

What HTTP protocols and standards are supported?

Billing & Pricing

How does the pay-per-watt model work?
Our pay-per-watt model ensures that you only pay for the power your deployments consume. The billing system monitors your real-time power consumption, allowing you to have greater control over costs. You can set usage alerts to notify you when consumption exceeds your set thresholds.
How do I charge my account?
Accounts must be charged in advance via IBAN/SEPA bank transfer: 1. Log in to the Billing Dashboard. 2. Copy your Account ID and the bank details. 3. Make a transfer with the reference format:

charge

Example: charge identity-abcdef

4.	Once we receive your transfer (typically 1–2 business days), your account balance will be credited automatically.

What are the bank details for charging my account?

  • IBAN: DE08100101236489344438
  • BIC: QNTODEB2XXX
  • Bank: Olinda Zweigniederlassung Deutschland, Warschauer Platz 11–13, 10245 Berlin
  • Beneficiary: DownToZero (Apimeister Consulting GmbH)
How long does it take until my balance is credited?
SEPA transfers usually take 1–2 business days. If your balance is not updated within 3 days, please contact support with proof of transfer.
Do I get an invoice for my payments?
Yes. Every top-up payment generates an official invoice (Vorauszahlungsrechnung) for the transferred amount. Invoices are tax-compliant and can be downloaded from the Billing Dashboard after your payment is processed.
Do I get an invoice for monthly usage?
No. Only prepayments (top-ups) are invoiced. Monthly usage is shown in your dashboard as a consumption report, but it is not invoiced separately. This ensures invoices always match your actual payments, which is required for German/EU accounting.
What happens if I forget to include the reference code?
If the transfer reference (e.g., charge identity-abcdef) is missing or incorrect, your payment may not be allocated automatically. Please contact support and provide proof of transfer so we can manually assign it to your account.
Can I get a refund for unused balance?
No. Prepaid balances are non-refundable but remain in your account until fully consumed.
Are there any free-tier options?
At this time, we do not offer a free tier. However, we provide flexible pricing based on your real-time consumption, allowing you to optimize costs according to your needs.

Security Questions

Is my data secure?
Yes, DowntoZero Cloud takes security seriously. We implement several layers of security to protect your data, including: • Encryption at rest and in transit • Role-based access control (RBAC) for managing permissions • Secrets management to securely store sensitive information
How can I manage access to my cloud resources?
You can manage access through role-based access control (RBAC), allowing you to assign specific permissions to users and services. This ensures only authorized users can access critical resources.
