The Fetch Crude Oil Inventory Data API returns closing crude oil stocks by country and by United States storage hub. Values are in thousand barrels. Coverage includes countries that report stocks and hubs such as Cushing, Oklahoma, the Strategic Petroleum Reserve and the five PADD regions. The live commodity code is crude_oil. Use List Commodities to read the catalog, Get Commodity for the profile and history start, List Commodity Areas for country and hub codes, Latest Inventory for the current level of each area, Inventory Time Series for history, and Inventory Changes for the move versus the previous period. Filter a series or a change with area codes such as US, JP or US-CUSHING. Wheat, corn, natural gas, lithium and copper are listed as planned, and inventory calls for those codes return not available until they go live.
Thousand barrels. Inventory responses include unit set to thousand_barrels. Get Commodity returns the same unit on the commodity profile.
Closing crude oil stocks by country and by United States hub, in thousand barrels. Each row has the area, the period and the stock level. Inventory Changes also returns the change versus the previous period and the percent change.
Countries that report stocks, plus United States hubs. Hubs include Cushing, Oklahoma, the Strategic Petroleum Reserve and PADD regions 1 through 5. Area codes look like US, JP and US-CUSHING.
Pass commodity crude_oil and area US-CUSHING to Latest Inventory, Inventory Time Series or Inventory Changes. US-CUSHING is the hub code for Cushing, Oklahoma.
Get Commodity returns history_from. For crude oil that date is 1982-08-20 on the United States series. Other countries start on the first period that exists for that area. Set from on Inventory Time Series to choose the start date.
Crude_oil is live. Wheat, corn, natural gas, lithium and copper are in the catalog with status planned. An inventory call for a planned code returns not available until that commodity goes live.
Each endpoint returns specific crude oil inventory data. For example, Latest Inventory provides current stock levels, Inventory Time Series offers historical data, and Inventory Changes shows stock variations over time. Each response includes relevant metrics and area details.
Key fields include "area" (location code), "name" (location name), "period" (date of data), "value" (stock level in thousand barrels), and "reliability" (data source reliability). These fields help users understand inventory levels and their context.
Response data is structured in JSON format, with a main object containing metadata and a "data" array. Each entry in the array corresponds to a specific area, detailing its stock level, period, and reliability, making it easy to parse and analyze.
Parameters vary by endpoint. For example, Latest Inventory accepts area codes to specify locations, while Inventory Time Series allows users to set date ranges using "from" and "to" parameters. This customization helps tailor data requests to specific needs.
The API covers crude oil inventory data for various countries and U.S. hubs, including Cushing, the Strategic Petroleum Reserve, and PADD regions. This broad coverage allows for comprehensive analysis of global and regional oil stocks.
Data accuracy is maintained through regular updates from reliable sources, including government reports and industry publications. The "reliability" field in responses indicates the source's credibility, helping users assess data quality.
Typical use cases include market analysis, predictive modeling, and inventory management. Analysts can use the data to forecast trends, assess supply levels, and inform investment decisions based on crude oil stock changes.
Users can analyze the data by comparing stock levels across regions, tracking historical trends, and assessing changes over time. Utilizing the "change" and "change_pct" fields in Inventory Changes can help identify significant fluctuations in inventory levels.
