Oil Inventories API
OilPriceAPI provides an oil inventories API for EIA Weekly Petroleum Status Report data, including commercial crude stocks, SPR levels, Cushing storage, PADD regions, and week-over-week changes.
Dataset overview
This page is for application programming interface intent: developers and analysts who want oil inventory data in JSON. It is not a page about the American Petroleum Institute organization, and the copy explicitly orients readers toward EIA Weekly Petroleum Status Report data.
Oil inventories are weekly supply indicators, not continuous market ticks. Production workflows should store report date, week-over-week change, location, product type, and source so inventory builds and draws can be compared against crude price moves.
API paths to evaluate
GET /v1/ei/oil_inventories/summaryWeekly summary with commercial crude stocks, SPR, Cushing, and PADD data.
GET /v1/ei/oil_inventories/cushingCushing, Oklahoma storage records for WTI delivery hub analysis.
What teams get
EIA weekly inventory data
Built around Weekly Petroleum Status Report semantics, including report dates and weekly changes.
Draw and build context
Copy explains the difference between inventory draws and builds so the page answers analyst questions.
Cushing and SPR links
Internal links guide users to Cushing storage, SPR, and the broader inventory hub.
API intent-safe language
The page avoids ambiguity with the American Petroleum Institute and focuses on JSON API access.
Workflow-ready fields
Encourages teams to capture report date, product, location, and change fields in downstream systems.
Market context
Connects inventory data to WTI, Brent, production data, forecasts, and oil price data pages.
Common use cases
These pages are built for commercial search intent: compare the dataset, understand update semantics, and continue into an API key, documentation, pricing, or an adjacent market page.
Trading models
Join weekly inventory draws and builds to WTI, Brent, and futures datasets.
Research dashboards
Show commercial stocks, SPR, Cushing, and PADD regional levels in one interface.
Market commentary

Frequently asked questions
Is this oil inventories API about the American Petroleum Institute?
No. This page targets API as application programming interface intent. The inventory data described here follows EIA weekly inventory concepts such as commercial stocks, SPR, Cushing, PADD regions, draws, and builds.
How often does oil inventory data update?
US inventory data follows the weekly EIA publication cadence. API consumers should use report date and timestamp fields rather than assuming minute-by-minute inventory updates.
Can I get Cushing storage through the same API?
Yes. Cushing storage has a dedicated endpoint and a dedicated page because it is the WTI delivery hub and a high-value inventory signal.
What should I link this data to?
Most teams compare weekly inventories with WTI, Brent, futures curves, production data, and price forecasts. This page links to those adjacent OilPriceAPI pages.
