How Fuel Data Lab gets its fuel price results

Transparent sourcing and transformation steps so engineers can evaluate data quality.

Source ingestion

Fuel Data Lab ingests EIA-published fuel price datasets on a recurring pipeline, preserving product and geography context.

Normalization + canonical series mapping

Records are cleaned into stable product/geo schemas with canonical series IDs so applications can query consistent endpoints.

API + analytics derivation

REST endpoints expose latest and historical prices, while derived metrics, events, spreads, and scenario tools build on the same normalized series.

Fuel Data Lab sells both API access and embeddable widgets. Start with /docs for integration details, or visit the home page for the product overview.
