One self-service plan

For teams that need repeatable municipality research without maintaining their own government-data pipeline. Use the API from your application or ask the same questions through an MCP-compatible assistant.

A municipality lookup uses 1 credit, a district summary uses 3, a comparison or ten-year history uses 5, and a search uses 10. The plan is self-service and does not include custom analysis or implementation work.

If a limit is reached, the request is rejected (HTTP 429); there is no overage charge. The monthly credit allowance resets on the 1st of each UTC calendar month.

There is no minimum term. The subscription renews automatically each month at ¥12,800 until canceled. At launch, billing email changes will not be available in the Stripe Customer Portal.

Use the REST API over HTTPS, or connect with an MCP client that follows the published MCP specification.
