Is there a free API for heavy electrical equipment data?

Yes, three. data.gov's catalog API is fully free - DEMO_KEY allows 30 requests/hour and an api.data.gov key lifts that to 1,000 - across 552,271 harvested US datasets. The IEC Standards Webstore's REST search API is free for metadata on ~30,482 publications, with standards themselves costing CHF 100-400. EPRI's GraphQL endpoint is free for metadata on ~359 transformer-related records.

Can I use the Kaggle electric motor temperature dataset in a commercial product?

Only under share-alike. The 185-hour, 2 Hz PMSM dataset (~2 million rows, 122 MB zipped) is commercial delivery terms-SA 4.0: attribute the Kirgsn/UPB dataset and IEEE paper 9296842 in publications, and derivatives you distribute must carry the same license. The companion Electrical Fault Detection & Classification set is commercial delivery terms, with no attribution or share-alike strings.

Do I need to scrape marketplaces for transformer price data?

For live supplier quotes, yes. Made-in-China embeds schema.org JSON-LD per listing but pairs robots.txt disallows with an anti-bot challenge; IndiaMART exposes full records in a window.__INITIAL_STATE__ JSON blob without authorizing scraping; Alibaba's /trade/search is blocked by baxia/sufei CAPTCHA. All prices are indicative supplier quotes, not executed transactions.

Which heavy electrical equipment datasets can I redistribute?

The commercial delivery terms fault-detection set redistributes freely, UK ONS PRODCOM ships under Open Government Licence v3.0 with attribution, and most federal records on data.gov are commercial delivery terms per publisher. The documents cannot be reshared: IEC prohibits redistribution of purchased PDFs, CIGRE watermarks downloads to purchaser accounts, and EPRI reports require membership.
