US natural gas (Henry Hub) fundamentals as clean, LLM-ready data — the energy-commodities ETL you would otherwise build yourself.

  • LNG — daily feedgas nowcast stitched from six operators' split pipeline EBBs, plus plant outages and capacity offline
  • EIA storage — our estimate of the weekly report before it is published, with realised error and out-of-sample accuracy
  • Production — US dry gas nowcast, month by month
  • Weather — 7-day CONUS cooling and heating degree days from GFS, ECMWF and NOAA CPC
  • Market — Henry Hub forward curve by delivery month and weekly CFTC COT positioning
  • News — plant outages, Gulf storms and market stories, each with a direction and strength read
  • Pressure summary — our own reading of which way every fundamental presses, and the rendered chart cards behind it

Works without credentials: every tool answers the same fields about a week old, so an agent can evaluate before anyone pays.

Data and analysis, not investment advice. Every model output arrives with its vintage and its measured margin of error, so you can weigh it before it touches a decision — statistical estimates guarantee no profit.

get_us_natural_gas_fundamental_scoreComposite fundamental pressure score for US natural gas / Henry Hub (-100..+100), built from 5 z-normalized signals (EIA storage vs 5-yr norm, 4-week surplus change, power burn, 7-day cooling and heating demand), with per-signal breakdown, its percentile against its own history and the latest NOAA degree-day forecast revision. ALWAYS returns the score's measured out-of-sample accuracy (walk-forward, against a baseline) and a disclaimer: this is market analysis, NOT investment advice. Set include_history=true for the daily score series with Henry Hub spot prices (~1000 points, off by default). Demo scope returns a 14-day-delayed score without the signal breakdown.
get_us_natural_gas_storage_nowcastEIA weekly natural gas storage report (Bcf, lower-48 working gas): the released headline injection/withdrawal plus, on pro scope, `pending` — our estimate of the report that has NOT been published yet, built from weather-driven demand and LNG feedgas components — and `last_verified` (estimate vs actual with realized error), alongside out-of-sample accuracy and backtest stats. Demo scope returns only the already-published actual.
get_us_natural_gas_production_nowcastDaily/monthly US dry natural gas production nowcast (Bcf/d), estimated from the year-ago level scaled by a YoY growth trend and anchored to news, with a per-month series (est vs EIA actual once published). Demo scope hides the freshest month's estimate.
get_us_lng_feedgasDaily LNG feedgas for US liquefaction terminals (Bcf/d) — the export pull on the domestic natural gas balance, nowcast from pipeline nominations on the terminals' electronic bulletin boards (split across operators, no single public source). Returns today's total with a regime label (loose / below_normal / normal / tight) measured against nameplate capacity and the 30-day mean, utilization, and the daily history. Pro scope adds the per-terminal breakdown, the measured-vs-estimated split and `movers` — who drove the change versus yesterday. Demo scope returns the same fields, breakdown included, as of a week ago.
get_us_lng_plant_outagesOperating status of every US LNG export plant (Sabine Pass, Corpus Christi, Freeport, Plaquemines, Calcasieu Pass, Cameron, Cove Point, Golden Pass, Elba Island): online / partial / down / ramping, current flow versus nameplate, capacity offline in Bcf/d and total ramping capacity. Status is inferred automatically — pipeline measurement first, news second — and each record says which source decided it. Pro scope adds the news headline behind the status and the start/end dates it claims. Demo scope lags 7 days.
get_us_natural_gas_weather_modelsWeather forecasts that drive US natural gas demand: 7-day population-weighted CONUS cooling and heating degree days from the GFS and ECMWF runs, the change versus the previous day's run, the GFS-ECMWF spread, the per-day degree-day profile, and the latest NOAA CPC forecast revision with its percentile. Full data on both scopes.
get_henry_hub_forward_curveHenry Hub natural gas futures forward curve by delivery month: price, session move, volume, and the same months a week, a month and a year ago for year-over-year context. Pro scope adds today's live prices and the curve-shape read — how much of the front-end move reached the far end and how unusual that pass-through is against two years of comparable days (a front-only move is a near-term balance story, a parallel shift is not). Market context, not investment advice.
get_henry_hub_cot_positioningSpeculative positioning in Henry Hub natural gas from the weekly CFTC Commitments of Traders report (futures and options combined): managed money net position, its weekly change, its percentile against three years of history, producer net, open interest and its change, plus a plain-English read. Reports lag the market — `days_stale` says by how much. Full data on both scopes.
get_us_natural_gas_news_contextRecent events moving US natural gas: LNG plant outages and restarts, Gulf storms, and market-wide stories, each with its source link. Pro scope adds our reading of every story — bullish / bearish / neutral, a 1-5 strength score explicitly gated on whether the story reaches Henry Hub (US liquefaction runs near its ceiling, so foreign demand shocks often move JKM and TTF but not the domestic balance) and whether it is already priced in, plus machine-readable facts (plant, status, Bcf/d, dates) and a plain-English summary. Demo scope returns the same reading for stories older than a week and headlines for the fresh ones.
get_us_natural_gas_pressure_summaryOur reading of every US natural gas fundamental in one call: for each factor — LNG feedgas, LNG plant outages, weather-model shifts, the EIA weekly injection pace, the composite fundamental score and its 30-day trend, power burn against normal and NOAA cooling demand — the direction of pressure on Henry Hub (bullish / bearish / neutral), its strength (moderate / strong), the number driving it with the thresholds used, and a plain-English sentence. Ends with an overall roll-up: the score, the signals pushing it down and up with their contributions, and any strong factor sitting outside the score. Direction is the sign of a deviation from normal, not a probability that price moves. Demo scope returns the same shape on delayed data.
get_us_natural_gas_chartA ready-made chart of US natural gas fundamentals as a PNG image, the same card we publish to our own channel: LNG feedgas, the fundamental score with its signal contributions, GFS/ECMWF weather runs, EIA storage against the 5-year normal, a Gantt of liquefaction outages, the Henry Hub forward curve, or CFTC managed-money positioning. Use it when a human is going to look at the answer — the numbers behind every card are available as data from the other tools. `kind` is one of lng_feedgas, fundamental_score, weather_models, storage, lng_outages, forward_curve, cot_positioning. Requires a token: charts are the one thing demo scope cannot serve delayed.
