Kasanegi Data APIs

Japanese public data as APIs that AI agents can call directly, from Kasanegi, an R&D studio.

Kasanegi has built and served a family of data APIs for AI agents since before the studio opened, through kasanegi.com, the RapidAPI marketplace and MCP. The family is being integrated into one platform. As one example from it, the ten APIs of JP Local Pack are open free of charge: payroll deductions, social insurance grades, withholding income tax (all 1,856 cells of the National Tax Agency monthly table), consumption tax, national holidays, corporate numbers, the qualified invoice issuer registry and Peppol invoice validation.

About this repository

This is the public companion of the private main repository. It first carried the earliest datasets and x402 work from which the current family grew: Japanese food composition, the SPDX license list, and a pay-per-call weather API settled in USDC on Base mainnet.
