MyAPIs: A Japanese REST API Test Zoo

Why it surfaced

MyAPIs offers 13 reusable data resources—from prefectures and Japanese eras to proverbs and shogi pieces—alongside five generators and an API Zoo covering 94 HTTP/API patterns. Its consistent endpoints, open CORS policy, and copy-ready curl, JavaScript, and Python examples make it unusually practical for testing real client behavior.

A free, authentication-free REST API suite serving Japanese datasets, generators, and a broad set of HTTP test scenarios.
