Planned spec: OpenAPI 3.1. Model map: llms.txt · llms-ja.txt.

Planned tools

ACP, UCP, and AP2 are checkout protocols for a seller. This service refers people to proxies and does not take payment, so those protocols are not implemented.

Repository only

These commands are for a checkout of this repository. They are not the public site. npm run dev:api listens on 127.0.0.1:8788. npm run build:mcp writes dist/japanlanded-mcp.js. The package is not on npm. api.japanlanded.com does not answer.
