curl -X PUT "https://api.eustore.dev/my-ai-bucket" \
  -H "Authorization: AWS4-HMAC-SHA256 ..." \
  -H "x-amz-content-sha256: UNSIGNED-PAYLOAD"

Upload a File (curl)

# Upload an object to your bucket
curl -X PUT "https://api.eustore.dev/my-ai-bucket/model-v1.bin" \
  -H "Authorization: AWS4-HMAC-SHA256 ..." \
  -H "Content-Type: application/octet-stream" \
  --data-binary @model-v1.bin

💡 See examples/curl_quickstart.sh for a complete script with proper AWS Signature V4 signing.

Python (boto3)

eustore.dev works with any S3 client library. Here's a quick Python example using boto3:

import boto3

# Connect to eustore.dev — European S3-compatible object storage
s3 = boto3.client(
    "s3",
    endpoint_url="https://api.eustore.dev",
    aws_access_key_id="your-access-key",
    aws_secret_access_key="your-secret-key",
    region_name="eu-central-fsn1",
)

# Create a bucket for your AI agent's data
s3.create_bucket(Bucket="my-ai-agent-data")

# Upload training data, model artifacts, logs — anything
s3.upload_file("model.pt", "my-ai-agent-data", "models/v1/model.pt")

# Download files programmatically
s3.download_file("my-ai-agent-data", "models/v1/model.pt", "local-model.pt")

# List all objects in your bucket
response = s3.list_objects_v2(Bucket="my-ai-agent-data", Prefix="models/")
for obj in response.get("Contents", []):
    print(f"  {obj['Key']} — {obj['Size']} bytes")

Node.js (AWS SDK)

const { S3Client, PutObjectCommand, GetObjectCommand } = require("@aws-sdk/client-s3");

// Connect to eustore.dev — European S3-compatible storage for AI agents
const s3 = new S3Client({
  endpoint: "https://api.eustore.dev",
  region: "eu-central-fsn1",
  credentials: {
    accessKeyId: "your-access-key",
    secretAccessKey: "your-secret-key",
  },
  forcePathStyle: true,
});

// Upload data from your AI agent or ML pipeline
await s3.send(new PutObjectCommand({
  Bucket: "my-ai-bucket",
  Key: "results/output.json",
  Body: JSON.stringify({ result: "success", confidence: 0.97 }),
  ContentType: "application/json",
}));

S3-Compatible API Reference

eustore.dev implements the Amazon S3 REST API, so any tool, library, or application that works with S3 works with eustore.dev.

Base URL

https://api.eustore.dev

Supported S3 Operations

Bucket Operations

Object Operations

Multipart Upload

Presigned URLs

Authentication

eustore.dev uses AWS Signature Version 4 for authentication. All standard S3 client libraries handle this automatically.

Response Format

All responses follow the standard S3 XML/JSON format, ensuring compatibility with existing tools and libraries.

Regions

eustore.dev operates from three EU data center regions, ensuring low latency across Europe and full data sovereignty:

Selecting a Region

# Python — specify region when creating client
s3 = boto3.client("s3",
    endpoint_url="https://api.eustore.dev",
    region_name="eu-north-hel1",  # Helsinki, Finland
    # ...
)

# AWS CLI
aws s3 ls --endpoint-url https://api.eustore.dev --region eu-central-fsn1

Pricing

Simple, transparent pay-as-you-go pricing with no hidden fees.

💡 AI Agent Friendly: No minimum commitment. Pay only for what your agents use. Scales from kilobytes to petabytes.

Free Tier

• 5 GB storage
• 1 GB egress per month

• 100,000 GET requests

Perfect for getting started with your AI agent prototype or development environment.

Payments

eustore.dev supports multiple payment methods for maximum flexibility — especially important for autonomous AI agents and crypto-native projects:

Programmatic Payments

# Check your current balance via API
curl "https://api.eustore.dev/account/balance" \
  -H "Authorization: Bearer YOUR_API_KEY"

# Top up with crypto (returns payment address)
curl -X POST "https://api.eustore.dev/account/topup" \
