What is E-Commerce API Security?

Understanding the threats to your revenue — and how to stop them

Your Revenue Runs on APIs

Every customer interaction is an API call. Product searches, inventory checks, cart operations, and checkout flows — all powered by APIs that attackers are actively targeting.

Product Search
GET /api/products?q=shoes
Inventory Check
GET /api/inventory/SKU-12345
Cart Operations
POST /api/cart/add
Checkout & Payment
POST /api/checkout

The Threats You Face

E-commerce APIs are prime targets. Attackers know that every API request represents potential revenue — and they're exploiting that at scale with automated attacks.

Scraping Bots
Competitors harvest prices and inventory to undercut you
Card Testing Fraud
Stolen cards validated against your checkout before being used
Inventory Hoarding
Bots hold items in cart, blocking real customers during flash sales
Promo Abuse
Automated systems exploit coupons and loyalty programs at scale

How G8KEPR Protects Your Store

Intelligent protection at every step of the customer journey

E-Commerce Request Flow
1. Customer Makes Request
Checkout attempt: POST /api/checkout {card: "4242..."}
2. G8KEPR Security Analysis
Real-time routing in <5ms
Bot Detection: Human vs automation fingerprinting
Card Testing: Velocity and pattern analysis
Fraud Signals: Device, IP, behavior scoring
Rate Limiting: Per-user, per-endpoint, per-IP
3. Legitimate Requests Proceed
Real customers checkout seamlessly → Payment processed → Order confirmed

✓ 99.7% legitimate traffic approved • Bots blocked instantly • Zero customer friction

Block Scraping Bots

ML-powered bot detection identifies automated scrapers harvesting your prices, inventory, and product data. Allow legitimate search engines, block competitors.

Protects against:
Price scrapingInventory monitoringCatalog harvesting

Stop Card Testing

Detect card testing attacks before fraudsters validate stolen cards against your checkout. Velocity analysis and pattern matching catch fraud rings.

Protects against:
BIN attacksCredential stuffingAccount takeover

Prevent Inventory Abuse

Stop bots from hoarding inventory during flash sales. Enforce fair cart limits, detect automated purchasing, and protect limited drops.

Protects against:
Cart hoardingSneaker botsFlash sale abuse

Real E-Commerce Attack Scenarios

Card Testing Fraud
Attack Pattern:
Fraudster tests 500 stolen cards against your checkout
Malicious Request:
POST /api/checkout (500 attempts, 2 min)
✓ Blocked By G8KEPR:
Velocity anomaly • Card BIN pattern flagged
Flash Sale Bot
Attack Pattern:
Sneaker bot adds 100 limited items to cart instantly
Malicious Request:

POST /api/coupons/validate (10,000 attempts)
✓ Blocked By G8KEPR:
Enumeration attack blocked • IP throttled

Every Tool Call Passes 7 Sequential Checks

5 Capabilities You Won't Find Anywhere Else

Not in Anthropic's MCP spec. Not in API gateways. Not in WAFs. Platform-level additions built for e-commerce workloads.

01

OS-Level MCP Sandbox

Subprocess MCP tools execute inside a hardened Linux sandbox. RLIMIT_CPU/AS/NOFILE/NPROC, setsid() process-group isolation, capability dropping, per-tool egress filtering, and shell binaries removed.

modules/mcp/sandbox/executor.py — 934 LOC
02

Tool Definition Hash Registry

SHA-256 hash of every tool definition pinned at tools/list. On every tools/call, the cached definition is re-hashed and compared. Drift raises MCPRugPullDetectedError, blocks execution, publishes a CRITICAL event.

modules/mcp/tool_registry.py • Redis-backed
03

Adaptive Z-Score Circuit Breaker

Statistical, not threshold-based. Z-score > 3.0 against per-hour time-of-day baselines (Black Friday vs Tuesday morning). 4 overlapping sliding windows (1m/5m/15m/1h). Progressive recovery (10→25→50→100%).

gateway/ — 2,208 LOC combined
04

Cross-Pillar Correlation

Every event linked across all four pillars via shared correlation ID. One query: "Show me everything that happened from this checkout — across MCP + API + Gateway + Verification." Architecturally impossible when layers are separate products.

mcp_contexts • parent-child causal chain
05

Hash-Chain Audit System

SHA-256 genesis block, each entry signing the previous. Three verification levels (full / single / last-N). Tamper-evident evidence for SOC 2 CC7.2 and PCI DSS Req 10.5 cardholder-data audit.

7 modules • 3,866 LOC combined

MCP Correlation Analyzer

Cross-session attack detection: 6-dimension risk score (max 110) across tool sensitivity, data volume, burst, denials, prior detections, and tool diversity. Catches coordinated bot waves and 24h slow-and-low patterns.

MCPCorrelationAnalyzer — alert at score > 50

One Correlation ID. All Four Pillars.

A checkout request traces forward to the AI bot-detection tool call it triggered, the store API response, and the verification check that caught any drift.

E-Commerce Security FAQs

Common questions about protecting your e-commerce APIs

Traditional WAFs protect against known attack signatures (SQL injection, XSS). G8KEPR focuses on API-specific threats: business logic abuse, bot automation, and fraud patterns. We work alongside your WAF, adding intelligent protection that understands e-commerce behavior. Your WAF blocks OWASP threats; G8KEPR stops bots scraping your catalog and fraudsters testing stolen cards.
