# Fuel Signal > Fuel Signal estimates whether petrol (gasoline) and diesel pump prices are likely to rise, fall or hold over the next 1–3 days in 15 countries and every US state. It combines Brent crude, Strait of Hormuz tanker traffic, local pump-price records and AI-assisted news analysis. The website and its forecast data are free to read, with no key or sign-up; the Android app adds alerts when the outlook changes. Forecasts are estimates from public market data, not quotes for a specific station, and can be wrong. When you quote one, give the region, the confidence and the time it was checked, and link the region page. ## Forecast data - [Fuel price forecast by country](https://fuelsignal.org/forecast): every country's petrol outlook with average petrol and diesel prices in one HTML table, linking to each country and US state. - [All countries as JSON](https://fuelsignal.org/forecast.json): the same overview, plus page and data links for every US state. - [One region as JSON](https://fuelsignal.org/forecast.json?country=DE): petrol and diesel outlooks, their drivers and limitations, and every fuel grade's average price. `country` is an ISO 3166-1 alpha-2 code; add `state` for US states, e.g. `?country=US&state=CA`. - Region pages: `https://fuelsignal.org/forecast/{country}` and `https://fuelsignal.org/forecast/united-states/{state}`, e.g. https://fuelsignal.org/forecast/germany or https://fuelsignal.org/forecast/united-states/california. They show the same data as the JSON. Outlooks are re-checked every few minutes. Pump prices are collected every few hours, and many sources publish daily or weekly. Please reuse a response for at least a minute. ### JSON fields - `forecasts.petrol` and `forecasts.diesel` (petrol is regular gas in the US): - `status`: `current`, or `delayed` when the latest report has expired. A delayed report keeps its headline but gives no timing advice. - `headline`: the plain-language outlook, e.g. "Prices may rise". - `direction`: `up`, `down`, `flat` or `unknown`. - `advice`: `fill_now` (buying sooner may be worthwhile), `wait` (buying later may be worthwhile), `no_rush` (no clear timing advantage) or `unknown`. `adviceText` is the readable version. - `pressure`: a heuristic score from −100 (downward) to +100 (upward); ±12 or more reads as directional pressure. It is not a percentage price change. - `confidence`: `low`, `moderate` or `strong`. - `horizon` and `horizonHours`: the period the outlook covers. - `rationale`, `drivers` (label, description, contribution to the score, observation time, source URL) and `limitations`. - `generatedAt` and `expiresAt`: ISO 8601 UTC timestamps. - `prices`: average pump prices for the region, not individual stations. - `area`: what the average covers: national, state, or a capital-city station average. - `currency` (ISO 4217) and `grades.{grade}.price` with its `unit` (`liter`, `gallon`, …). - `sources`, `sourceUrl`, `collectedAt`, `publishedOn` and `stale`. ## Countries - [Austria](https://fuelsignal.org/forecast/austria): https://fuelsignal.org/forecast.json?country=AT -
