Aprašymas
OilPriceAPI Fuel Widgets adds source-dated U.S. retail-fuel data to WordPress as shortcodes or a Gutenberg block.
Fuel Price Ticker
National U.S. diesel and regular gasoline averages. Each result shows its EIA observation week, weekly cadence, unit, and source.
U.S. Diesel Price
The national U.S. diesel retail average, quoted in USD per gallon and labeled with its observation week.
Fuel Surcharge Calculator
Calculates the percentage by which the weekly national diesel average exceeds a base price configured by the site owner. It does not describe the result as an industry standard or a contractual surcharge.
Features
- Source date, weekly cadence, currency, unit, and EIA attribution in every successful widget
- Dark and light themes
- Shortcodes and Gutenberg block
- Server-side requests with no remote executable code
- One-hour validated cache
- Last successful result for up to 48 hours after an error, visibly labeled as a cached copy
- Fail-closed handling for unavailable, rate-limited, timed-out, empty, or malformed responses
- No API key required for the public EIA series
External service
This plugin uses OilPriceAPI to retrieve the EIA retail-fuel series displayed by the widgets.
The WordPress server sends a GET request to https://www.oilpriceapi.com/api/widgets/fuel-prices at most once per hour while a page containing a widget is requested. OilPriceAPI receives the site server’s IP address and standard HTTP request metadata. The plugin does not send the visitor’s IP address, WordPress user data, page content, or an API credential.
The underlying retail-fuel observations come from the U.S. Energy Information Administration and are public domain at the source. OilPriceAPI delivers and validates the response; it does not grant rights in underlying data.

DUK
-
Do I need an API key?
-
No. These widgets use a public OilPriceAPI route restricted to two EIA public-domain retail-fuel series.
-
How current is the data?
-
EIA publishes these retail-fuel series weekly. Every successful widget shows the source observation as
Week offollowed by a date and saysUpdated weekly. -
The plugin can show its last successful response for up to 48 hours. That state is visibly labeled
Cached copy; service temporarily unavailable. After 48 hours, the price is removed and the widget links to the service status page. -
What does the plugin cache?
-
Only the validated fuel-price payload, its EIA source date, and the time it was retrieved. The fresh cache lasts one hour. The last-success cache lasts no more than 48 hours.
-
Can I display crude oil or natural gas prices?
-
Not with this public widget. OilPriceAPI does not hold downstream display or redistribution rights for the crude and natural-gas inputs previously shown by the ticker. Review the data-use guidance before publishing API data to third parties.
-
What happened to the carbon calculator and regional diesel display?
-
Version 1.1 retired the carbon calculator’s uncleared crude-price input and removed unsupported regional diesel output. An existing carbon shortcode shows a retirement notice instead of silently displaying a fabricated or uncleared value.
-
Where can developers get programmatic access?
-
See the API documentation and the official PHP SDK.
