Standard library only
No dependency install is required for the prepared client and quick start.
DEVELOPER KIT
Build Japan commerce features without integrating Japanese systems one by one.
Use dependency-light Python or strict TypeScript clients for Address, Business, Sellability, and Profitability. Every example reads JAPAN_API_KEY from the environment and preserves request IDs, source boundaries, warnings, and rate-limit errors.
Strict TypeScript
Uses the built-in Fetch API and a checked TypeScript configuration.
Environment first
The repository contains .env.example, fixtures, and no live credentials.
ONE CLIENT · FOUR APIS
Move from a company lookup to a product decision.
The full checked-in kit includes individual examples for all four APIs, an end-to-end Japan commerce readiness flow, fixture-backed tests, and MCP request examples.import os
from japan_api_store import JapanApiStore
client = JapanApiStore(os.environ["JAPAN_API_STORE_API_KEY"])
companies = client.search_business("Toyota Motor Corporation")
print(companies["candidates"][0])
decision = client.check_sellability({
"product_name": "Bluetooth speaker",
"category": "Electronics",
"wireless_function": True,
})
print(decision["decision"])Public repository connection
The official GitHub identity is japan-api-store. The production-ready kit is complete locally; repository access is not available to this deployment process, so no unofficial or wrong-account repository is linked as the canonical source.
