Torify — Japanese Locale APIs for AI Agents
Torify — Japanese Locale APIs for AI Agents
No Docker. No API key. No wallet setup. Just paste a URL into your MCP client and start calling Japanese locale primitives that standard libraries lack.
Torify gives AI agents the Japanese locale primitives that standard libraries lack — imperial era date conversion (wareki), qualified invoice number validation with NTA registry lookup, corporate number lookup (法人番号), postal code resolution, name romanization (Hepburn), and kanji-to-kana conversion via Yahoo! JLP. 10 free MCP tools backed by a 40-endpoint REST API. No authentication required for MCP. 100 calls/month free with email signup, or pay-per-call $0.02/call via x402, or $49/mo Pro subscription.
What Torify Solves
Japanese locale data is notoriously hard to get right in software: imperial era dates (wareki), qualified invoice T-numbers tied to Japan's NTA registry, 13-digit corporate numbers (法人番号), 7-digit postal codes that map to prefecture/city/town with kana readings, kanji name romanization for passports, geocoding via Japan's official GSI tiles, and law/regulation search via e-Gov. Standard i18n libraries don't cover these. Torify wraps 40 production-ready endpoints behind a single hosted MCP server.
