Government — entry 036 of 90

LocalGov.jp

Verified Jul 2026

LocalGov.jp is an independent developer's structured-data layer over Japan's national J-Grants system and 1,600+ municipal grant and subsidy programmes, plus a furusato nozei (hometown tax) gift database, normalized into JSON and AI-agent-friendly Markdown. Nearly every endpoint is free and keyless with CORS wide open to any origin, re-confirmed live against the real search API; a handful of premium AI-analysis endpoints use x402 USDC micropayments instead of a traditional key. It's not an official government site — it's a third-party aggregator that requires attribution back to each original government source.
