Verified rate data, one request away
Pipe current and historical electric and gas tariffs into your product in standardized JSON. Our analysts read the filings; your app gets clean components.
Three APIs, one standardized format
Electric utility rates
Current and historical schedules by state/province, utility, and zip code, with change detection on every component.
Natural gas utility rates
The same standardized JSON for gas tariffs: current and historical rates by jurisdiction and utility.
Default supply rates
Distribution utility supply components and rates for competitive markets, so your pricing engine always knows the default to beat.
Simple, predictable endpoints
Look up utilities by jurisdiction, schedules by utility, and components by schedule, with the same structure for electric and gas. History and change queries use the identical structure with a date range.
- Same pattern across electric, gas, and supply
- Query by state/province, utility, and zip
- Date-ranged history on every component
Know when a rate set or component changes
Poll the changes feed on your schedule to see which rate sets and components changed. Each change includes the new value and its effective date, verified by an analyst before it reaches the feed.
- Changes at rate-set and component level
- New value and effective date
- Poll on your schedule; keep caches honest
