Frequently Asked Questions

What payment methods and terms are supported?
We accept Visa, Mastercard, and corporate PayPal. All transactions are securely processed and screened via enterprise fraud prevention systems (including MaxMind minFraud). For Business and Enterprise tiers, we offer Net-30 and Net-60 invoicing via wire transfer or SEPA.
How does dynamic scaling and contract adjustment work?
Resource allocation can be dynamically scaled via the API or dashboard without downtime. Billing is calculated on a prorated, per-second basis. Standard plans have no lock-in. Custom enterprise contracts require a 30-day notice for structural resource downgrades.
Are there guarantees for Data Sovereignty?
Data sovereignty is mathematically guaranteed. All primary storage and active replicas are strictly confined to ISO 27001 certified, Tier IV facilities within the EU (Frankfurt and Amsterdam). Data never leaves the EEA.
What is the evaluation process for new enterprise clients?
We offer a fully-featured 14-day technical evaluation environment for validated corporate domains. To maintain platform integrity, stringent corporate identity verification is required. No credit card is needed during the PoC (Proof of Concept) phase.
How are compute and storage bursts handled?
Bursts exceeding your committed baseline are automatically accommodated to prevent latency, and are billed in arrears at standard enterprise overage rates. Automated hard-limits and budgetary alerting can be configured via IAM policies to control OpEx.

Quick Start

CloudStore uses standard S3-compatible authentication. Generate your Access Key and Secret Key from the dashboard under Settings → API Keys.

Authentication

All API requests require an HTTP Authorization header containing your API Access Key and Secret Key, signed using HMAC-SHA256 (AWS Signature V4).

Authorization: AWS4-HMAC-SHA256 Credential=CSAK.../20260611/eu-central-1/s3/aws4_request, ...

Upload an Object (AWS CLI)

We recommend using the official AWS CLI for interacting with your buckets. Simply point the endpoint URL to our European region.

aws s3 cp document.pdf s3://enterprise-data/ \
  --endpoint-url https://ro.cloudstorestorage.dev \
  --profile cloudstore

Upload an Object (Python Boto3)

For programmatic access, use the standard boto3 library. CloudStore is fully compatible with AWS Signature V4.

import boto3

s3 = boto3.client('s3',
    endpoint_url='https://ro.cloudstorestorage.dev',
    aws_access_key_id='YOUR_ACCESS_KEY',
    aws_secret_access_key='YOUR_SECRET_KEY'
)

s3.upload_file('document.pdf', 'enterprise-data', 'document.pdf')

Generate Presigned URL

Create a time-limited download link for sharing objects externally. Presigned URLs are generated locally by your client using your secret key.

url = s3.generate_presigned_url(
    ClientMethod='get_object',
    Params={'Bucket': 'enterprise-data', 'Key': 'reports/q1.pdf'},
    ExpiresIn=3600
)
print(url)

Error Codes

The API returns standard HTTP status codes. All error responses include a JSON body with code and message fields.

{
  "code": "NoSuchBucket",
  "message": "The specified bucket does not exist.",
  "request_id": "req_8f3a2b1c"
}

Rate Limits

API requests are rate-limited per plan tier. Developer: 100 req/s. Business: 1,000 req/s. Enterprise: custom. Exceeding limits returns 429 Too Many Requests with a Retry-After header.

SDKs & Libraries

Official SDKs are available for Python, Node.js, Go, and Java. Community-maintained libraries exist for Rust, PHP, and Ruby. All SDKs are open-source on GitHub.

Incident History

RESOLVED

Elevated API Latency in EU-Central-1

July 20, 2026 — 14:32 UTC to 15:07 UTC (35 min)

A network routing change in our Frankfurt data center caused elevated latency for approximately 8% of API requests. The issue was resolved by reverting the routing configuration. No data loss occurred.

RESOLVED

Scheduled Maintenance: NVMe Storage Upgrade

July 4, 2026 — 02:00 UTC to 04:15 UTC

Planned maintenance to upgrade storage nodes in EU-West-1 to NVMe Gen4. All tenants were notified 14 days in advance. Brief read-only windows occurred during failover testing.

Our Mission

CloudStore was founded in 2021 with a simple belief: enterprise storage should be fast, secure, and transparent. We saw teams struggling with the complexity and hidden costs of legacy cloud providers, and we built a platform that puts developer experience and data sovereignty first.

Today, over 2,400 businesses trust CloudStore to store and serve their most critical data. From startups deploying their first S3-compatible bucket to Fortune 500 companies running petabyte-scale analytics pipelines, our platform adapts to every workload.

Our Values

Data Sovereignty

Your data stays in the EU. Always. We operate exclusively within European jurisdictions and comply fully with GDPR, Schrems II, and national data protection laws.

Radical Transparency

No hidden fees, no surprise invoices, no vendor lock-in. Our pricing is published, our SLAs are contractual, and our status page shows real data.

Security by Default

Encryption at rest and in transit is enabled on every bucket, every plan. We undergo annual SOC 2 Type II audits and employ a dedicated security team.
