Ordinex US Energy Data — Energy Market Intelligence API
Energy-market data that doesn't suffer from
look-ahead bias.
EIA natural gas, storage, and crude prices, NOAA regional weather, and ISO/RTO wholesale power - normalized, point-in-time correct, and paired with factor scores that were actually walk-forward backtested, not just computed and shipped. One REST API, built to feed trading systems directly.
Why this matters
No look-ahead bias, and no accidentally-honest factor
Most energy-data feeds stop at "here's the number." This one goes one step further: every factor was tested for whether it actually predicts anything, walk-forward, out-of-sample - and the honest misses are published right alongside the real ones. See the factor catalogue for the full tier breakdown.
Source publishes
EIA reports a weekly storage figure days after the "as of" date it actually describes.
Reporting lag respected
A real min_lag_days safety margin per source - a factor is never paired against a target move that happened before it was actually public.
Nothing overwritten
Every raw fact and factor observation is append-only, insert-if-not-exists - a later revision never silently replaces history.
Walk-forward tested
One held-out fold per calendar year, never fit and tested on the same window.
Scored, not just shipped
A five-dimension quality scorecard decides the tier - sign consistency, crisis robustness, and economic effect size, not just "it correlates."
Architecture
How data becomes a validated signal
Connectors
EIA v2 (natural gas, storage, petroleum, electricity) and NOAA CDO, direct public-domain federal sources. CAISO/NYISO wholesale power feeds the internal factor library.
Storage
Append-only, point-in-time - queries reconstruct exactly what was knowable as of any date.
Scheduler
Refreshes every source automatically (daily or weekly, matched to how often it actually updates) and recomputes factors forward.
Backtest engine
Bucket analysis, regime splits, annual walk-forward, and an economic-significance effect size - before a factor ever reaches the API.
REST API
Raw series, factor observations, rankings, and screens - all over HTTP, scoped to what's actually legally cleared to serve.
Factor library
Tiered by real evidence, not an undifferentiated list
Every factor below is sourced from EIA or NOAA - public-domain federal data, cleared for commercial use (see the legal review). Factors are tiered by how they scored on a five-step validation framework: predictive content, monotonicity, regime stability, mandatory walk-forward out-of-sample testing, and economic significance - not just whether they "worked" once. The full methodology and every real backtest result lives in the factor catalogue.
Quickstart
From zero to your first factor score
Get an API key
Sign up below for a free self-service key, or provision one directly if you're running your own instance.
Call an endpoint
Send it as the X-API-Key header on every request.
Read the response
The top 5 storage regions ranked by their latest percentile value, most recent observation on/before today.
Reference
Full endpoint reference, generated from the API itself
Every request/response shape below is generated straight from the running API, so it never drifts out of sync with what's actually deployed.
Access
Get an API key
Free during early access - one active key per email. Every self-service key gets the full public factor library above; the CAISO/NYISO spark-spread factors stay internal-only regardless of key, pending the ISO licensing question noted in the factor library.
