OpenRegistry vs LocalGov.jp: common questions

Which is more reliable, OpenRegistry or LocalGov.jp?

Only LocalGov.jp is on our probe schedule so far (—% uptime over 90 days). The other is catalogued but not yet live-checked, so we can't compare measured reliability head-to-head — check the uncovered API's own status page for now.

Do OpenRegistry and LocalGov.jp need an API key?

LocalGov.jp needs no key, while OpenRegistry requires a free API key. If you want to start calling without signup, reach for LocalGov.jp first.

Can I call OpenRegistry and LocalGov.jp from the browser?

Yes — both OpenRegistry and LocalGov.jp send CORS headers over HTTPS, so front-end code can fetch either directly with no backend proxy. That makes them easy to swap in a client-side app while you compare responses.

Are OpenRegistry and LocalGov.jp free for commercial use?

OpenRegistry has unclear commercial terms, and LocalGov.jp allows commercial use on its free tier. We track service terms and the data license as separate fields — see the Commercial use and Data license rows above, and confirm both before shipping either in a paid product.
