What is WaveGuard?

WaveGuard is a general-purpose anomaly detection API. Send it any data — server metrics, financial transactions, log files, sensor readings, time series — and get back anomaly scores, confidence levels, and explanations of which features triggered the alert.

No training pipelines. No model management. No state. One API call.

Your data  →  WaveGuard API (GPU)  →  Anomaly scores + explanations

Under the hood, it uses GPU-accelerated wave physics instead of machine learning. You don't need to know or care about the physics — it's all server-side.

If you look at Modal, you will see deployed functions (for example fastapi_app, gpu_scan, gpu_fingerprint). Those are compute/runtime units, not the HTTP route list.

  • OpenAPI docs: https://gpartin--waveguard-api-fastapi-app.modal.run/docs
  • OpenAPI JSON: https://gpartin--waveguard-api-fastapi-app.modal.run/openapi.json
How does it actually work?

Your data is encoded onto a 64³ lattice and run through coupled wave equation simulations on GPU. Normal data produces stable wave patterns; anomalies produce divergent ones. A 52-dimensional statistical fingerprint is compared between training and test data. Everything is torn down after each call — nothing is stored.

The key advantage over ML: no training data requirements (2+ samples is enough), no model drift, no retraining, no hyperparameter tuning. Same API call works on structured data, text, numbers, and time series.

Benchmarks (v2.2)

WaveGuard v2.2 vs scikit-learn across 6 real-world scenarios (10 training + 10 test samples each).

TL;DR: WaveGuard v2.2 wins 4 of 6 scenarios and averages 0.76 F1 — competitive with sklearn methods while requiring zero ML expertise.

F1 Score (balanced precision-recall)

ScenarioWaveGuardIsolationForestLOFOneClassSVM
Server Metrics (IT Ops)0.870.710.870.62

Sparse Features (Logs)0.720.900.820.78
Average0.760.740.790.68

What's new in v2.2

Multi-resolution scoring tracks each feature's local lattice energy in addition to global fingerprint distance. This catches subtle per-feature anomalies (like 3 of 10 IoT sensors drifting) that v2.1's global averaging missed. IoT F1 improved from 0.30 → 0.87.

When to choose WaveGuard over sklearn

Expanded benchmarks: WaveGuard ranks #1 in F1 score on all 12 public benchmark datasets. See the full comparison on HuggingFace.

Real-World Validation: Crypto Crash Detection

WaveGuard powers CryptoGuard, a crypto risk scanner. Backtested against 7 historical crashes (LUNA, FTX, Celsius, 3AC, UST, SOL/FTX, TITAN):

MethodRecallAvg Lead TimeFalse Positive Rate
WaveGuard100% (7/7)27.4 days6.1%
Z-score baseline100% (7/7)28.4 days29.9%
Rolling volatility86% (6/7)15.5 days4.0%

WaveGuard flagged FTT (FTX token) at CAUTION on October 16, 2022 — 23 days before the 94% crash — while z-score analysis showed nothing unusual.

5× fewer false alarms than statistical baselines with the same recall. Full results: CryptoGuard backtest.

Install

pip install WaveGuardClient

That's it. The only dependency is requests. All physics runs server-side on GPU.

Quickstart

The same scan() call works on any data type. Here are three different industries — same API:

Detect a compromised server

from waveguard import WaveGuard

wg = WaveGuard(api_key="YOUR_KEY")

result = wg.scan(
    training=[
        {"cpu": 45, "memory": 62, "disk_io": 120, "errors": 0},
        {"cpu": 48, "memory": 63, "disk_io": 115, "errors": 0},
        {"cpu": 42, "memory": 61, "disk_io": 125, "errors": 1},
    ],
    test=[
        {"cpu": 46, "memory": 62, "disk_io": 119, "errors": 0},    # ✅ normal
        {"cpu": 99, "memory": 95, "disk_io": 800, "errors": 150},   # 🚨 anomaly
    ],
)

for r in result.results:
    print(f"{'🚨' if r.is_anomaly else '✅'}  score={r.score:.1f}  confidence={r.confidence:.0%}")

Flag a fraudulent transaction

result = wg.scan(
    training=[
        {"amount": 74.50, "items": 3, "session_sec": 340, "returning": 1},
        {"amount": 52.00, "items": 2, "session_sec": 280, "returning": 1},
        {"amount": 89.99, "items": 4, "session_sec": 410, "returning": 0},
    ],
    test=[
        {"amount": 68.00, "items": 2, "session_sec": 300, "returning": 1},     # ✅ normal
        {"amount": 4200.00, "items": 25, "session_sec": 8, "returning": 0},     # 🚨 fraud
    ],
)

Catch a security event in logs

result = wg.scan(
    training=[
        "2026-02-24 10:15:03 INFO  Request processed in 45ms [200 OK]",
        "2026-02-24 10:15:04 INFO  Request processed in 52ms [200 OK]",
        "2026-02-24 10:15:05 INFO  Cache hit ratio=0.94 ttl=300s",
    ],
    test=[
        "2026-02-24 10:20:03 INFO  Request processed in 48ms [200 OK]",                  # ✅ normal
        "2026-02-24 10:20:04 CRIT  xmrig consuming 98% CPU, port 45678 open",             # 🚨 crypto miner
        "2026-02-24 10:20:05 WARN  GET /api/users?id=1;DROP TABLE users-- from 185.x.x",  # 🚨 SQL injection
    ],
    encoder_type="text",
)

Same client. Same scan() call. Any data.

Use Cases

WaveGuard works on any structured, numeric, or text data. If you can describe "normal," it can detect deviations.

IndustryWhat You ScanWhat It Catches
DevOpsServer metrics (CPU, memory, latency)Memory leaks, DDoS attacks, runaway processes
FintechTransactions (amount, velocity, location)Fraud, money laundering, account takeover
SecurityLog files, access eventsSQL injection, crypto miners, privilege escalation
IoT / ManufacturingSensor readings (temp, pressure, vibration)Equipment failure, calibration drift
E-commerceUser behavior (session time, cart, clicks)Bot traffic, bulk purchase fraud, scraping
HealthcareLab results, vitals, biomarkersAbnormal readings, data entry errors
Time SeriesMetric windows (latency, throughput)Spikes, flatlines, seasonal breaks

The API doesn't know your domain. It just knows what "normal" looks like (your training data) and flags anything that deviates. This makes it general — you bring the context, it brings the detection.

Supported Data Types

All auto-detected from data shape. No configuration needed:

TypeExampleUse When
JSON objects{"cpu": 45, "memory": 62}Structured records with named fields
Numeric arrays[1.0, 1.2, 5.8, 1.1]Feature vectors, embeddings
Text strings"ERROR segfault at 0x0"Logs, messages, free text
Time series[100, 102, 98, 105, 99]Metric windows, sequential readings

Every example is a runnable Python script that hits the live API:

MCP Server (Claude Desktop)

The first physics-based anomaly detector available as an MCP tool. Give any AI agent the ability to detect anomalies — zero ML knowledge required.

Quick setup

{
  "mcpServers": {
    "waveguard": {
      "command": "uvx",
      "args": ["--from", "WaveGuardClient", "waveguard-mcp"]
    }
  }
}

Then ask Claude: "Are any of these sensor readings anomalous?" — it calls waveguard_scan automatically.

Available MCP tools

ToolDescription
waveguard_scanDetect anomalies in any structured data
waveguard_scan_timeseriesAuto-window time-series and detect anomalous segments
waveguard_healthCheck API status and GPU availability

See the MCP Agent Demo for a working example, or the MCP Integration Guide for full setup.

Azure Migration

Azure Anomaly Detector retires October 2026. WaveGuard is a drop-in replacement:

# Before (Azure) — 3+ API calls, stateful, time-series only
client = AnomalyDetectorClient(endpoint, credential)
model = client.train_multivariate_model(request)   # minutes
result = client.detect_multivariate_batch_anomaly(model_id, data)
client.delete_multivariate_model(model_id)

# After (WaveGuard) — 1 API call, stateless, any data type
wg = WaveGuard(api_key="YOUR_KEY")
result = wg.scan(training=normal_data, test=new_data)  # seconds

See Azure Migration Guide for details.

API Reference

wg.scan(training, test, encoder_type=None, sensitivity=None)

ParameterTypeDescription
traininglist2+ examples of normal data
testlist1+ samples to check
encoder_typestrForce: "json", "numeric", "text", "timeseries" (default: auto)
sensitivityfloat0.5–3.0, lower = more sensitive (default: 1.0)

Returns ScanResult with .results (per-sample) and .summary (aggregate).

wg.health() / wg.tier()

Health check (no auth) and subscription tier info.

Advanced intelligence methods (v3.3.0)

  • wg.counterfactual(...)
  • wg.trajectory_scan(...)
  • wg.instability(...)
  • wg.phase_coherence(...)
  • wg.interaction_matrix(...)
  • wg.cascade_risk(...)
  • wg.mechanism_probe(...)
  • wg.action_surface(...)
  • wg.multi_horizon_outlook(...)

These map directly to /v1/* intelligence endpoints and return the raw JSON payload for maximal compatibility with rapidly evolving server-side response schemas.

Error Handling

from waveguard import WaveGuard, AuthenticationError, RateLimitError

try:
    result = wg.scan(training=data, test=new_data)
except AuthenticationError:
    print("Bad API key")
except RateLimitError:
    print("Too many requests — back off and retry")
