METASTATE is a free-energy anomaly detector. The same three diagnostics — surprise, causal coherence, symbolic structure — work across cardiology, geophysics, finance, industry, networks, and language. Each card below ships a domain-realistic sample signal and runs it on the live kernel with one click. No login, no wallet, no setup.
Each card generates a synthetic-but-realistic signal in your browser, sends it to /v1/anomaly/score, and renders the diagnostics. The samples are crafted to contain a planted anomaly — so you can see the kernel actually flag it. Then swap our sample for your own data.

ECG Arrhythmia Detection
Clinical-rhythm strips with an intercurrent premature ventricular contraction (PVC) buried in normal sinus. The kernel learns the baseline rhythm in seconds and raises free-energy on departures, without supervised training.
01/06
signal — — samples · sampling — Hz · planted —
Expected result: elevated free-energy F(t) near the PVC, causal coherence 𝒞(t) spike where the morphology breaks, and a flagged verdict. Spectral β < −1.4 signals the QRS-like pulse train.
Press RUN ANOMALY SCORE to send this ECG strip to the kernel and see the diagnostics.

Schumann · Geomagnetic Anomalies
The Earth-ionosphere cavity resonances near 7.83, 14.3, 20.8, 27.3, 33.8 Hz, with a transient mode-amplitude excursion. Same physics as the live hero waterfall — sent through the kernel as a flat numeric series.
02/06
spectrum — — bins · — modes · planted —
Expected result: moderate F(t), with 𝒞(t) firing on the transient. The signal is multi-modal so spectral β sits near −1; the planted excursion lifts compression ratio.
Press RUN ANOMALY SCORE to send the spectrum to the kernel.

Financial Tick Anomalies
Mid-price tick series with a microstructure burst — momentary volatility cluster, mean-reverting within seconds. The kind of pattern that's noise on a 1-minute candle and signal at tick resolution.
03/06
ticks — — samples · drift — · planted —
Expected result: spectral β near zero (white-ish noise) outside the burst; AR(1) φ tightens during the cluster; verdict flagged when the kernel sees the variance regime change.
Press RUN ANOMALY SCORE to send the tick series to the kernel.

Vibration · Predictive Maintenance
Rotating-machinery accelerometer trace with a developing bearing fault — a low-amplitude sub-harmonic emerging beneath the fundamental rotation frequency. The textbook precursor for catastrophic failure.
04/06
trace — — samples · base — Hz · planted —
Expected result: the EML symbolic head should recover a clean closed form for the baseline and leave a structured residual — that residual is the fault. F(t) climbs steadily through the trace.
Press RUN ANOMALY SCORE to send the accelerometer trace to the kernel.
Vertical 05 · Infrastructure
Network Telemetry · Latency Spikes
HTTP request latency series with a covert slow-burn — the kind of pattern that hides under a normal SLO chart but is visible as a coherence drift. Useful for SRE on-call, DDoS pre-detection, CDN edge monitoring.
05/06
series — — samples · baseline p99 — ms · planted —
Expected result: baseline causal coherence stays low; the planted drift raises 𝒞(t) before the mean shifts enough to trip a threshold alarm. F(t) climbs gradually — early-warning behaviour.
Press RUN ANOMALY SCORE to send the latency series to the kernel.

Text · LLM Output Auditing
Two short documents passed in TEXT mode — one drawn from a natural English corpus, one with a degenerate-repeat block in the middle (a common LLM failure mode). Compare Zipf α, conditional entropy, compression ratio side by side.
06/06
Expected result: the degenerate string collapses Zipf α, drops conditional entropy H₁, and lifts compression ratio toward the floor. The kernel flags it; the normal sample does not.
Press SCORE BOTH to run each sample and compare diagnostics.
Volume Pricing
Move past per-call. Lock a tier.
Per-call USDC is right for trials, integrations, and casual use. For a research lab, monitoring stack, or production workload, lock a monthly tier paid up front in USDC. Same kernel, same endpoints, same diagnostics — just no per-call settlement on the hot path.
