# Japan Data APIs for AI Agents (agentic-jp.com)

> Eight production APIs covering the data an agent needs to operate in the Japanese market — address normalization, furigana readings, real-time transit, National Diet records, holidays, JMA weather, the 5.78M-company corporate registry, and a travel eSIM concierge. Every endpoint is payable per call with USDC via the x402 protocol (Base / Polygon / Solana, Coinbase CDP facilitator). No API keys, no signup.
