Amanoki.
Decision-support computation for wholesale electricity markets. Regime labels, empirical spike probabilities, and the thin API layer a procurement or trading desk can wire into its own workflow. Four-state FSM with hysteresis and a scarcity-price override, tuned per market.

Markets
| Market | Coverage | Bar | Status |
|---|---|---|---|
| JEPX (Japan) | 9 areas + system price | 30 min | live |
| ERCOT (Texas) | 4 hubs + 2 load zones | 5 min | roadmap |
| PJM (Mid-Atlantic / Midwest) | 4 hubs | 5 min | roadmap |

"Live" means the ingest loop is running and the FSM has warmed up. "Roadmap" means the market is in the catalog and routed, but the adapter is unwritten — endpoints return warmup until we register for the data feed.

Response carries the current regime (low /
normal / high / scarcity),
the realised-volatility z-score, the latest price in the market's
native units, and the timestamp of the bar it came from.
Pricing

Paid tiers open when the billing stack lands. Until then every tier runs at the free rate limit. Enterprise is off by default — it exists as a placeholder for later volume, not an open sales channel today.
Why regime, not forecast
Procurement and trading teams don't need another price point estimate — they need to know whether the distribution around it just shifted. A scarcity-flagged 30-minute コマ on a cold winter morning moves a retailer's monthly cost more than ten forecasted points do. The API is the thin layer that stabilises that signal.
Status
JEPX is live and refreshed daily. Empirical spike-probability
tables (2 h and 4 h horizons, conditioned on local
hour-of-day and weekend) are live alongside the regime endpoint.
ERCOT, PJM, CAISO, AEMO, and NYISO are routed but wait on their
ingest adapters — see GET /v1/status for the current
coverage snapshot.
Not advice
Amanoki is a computational tool. We compute regime state, empirical spike probabilities, and calibration-scored forecast distributions. We do not give trading, procurement, hedging, or investment advice. Methodology and calibration are published openly so callers can audit the outputs. What you decide with this output is your responsibility.
