Tools

8 tools listed at last check
  • search_subsidies Search Japanese central + municipal subsidies. Combine keyword (Japanese), prefecture, municipality_code, category, or minimum amount. Returns up to `limit` records. Free.
  • get_subsidy_detail Fetch the full record for a single subsidy by id. Returns `_source` (LocalGov.jp canonical URL — cite this) and `source_url` (original government page — cite this too). Free.
  • get_municipality_grants List all subsidies for a single municipality by JIS X 0402 6-digit code. **Differentiator**: J-Grants public API has zero municipal-level entries; LocalGov.jp covers 1,627 municipalities (target 1,718). Free.
  • find_supplementary_grants Given a central J-Grants subsidy id, search for municipal grants that supplement it (e.g. national "事業再構築" + city-level "事業再構築追加上乗せ"). Heuristic title-token match. Free.
  • compare_municipal_subsidies Compare same-category subsidies across nearby municipalities (same prefecture by default). Useful for relocation / siting decisions. Free.
  • subscribe_changes Create a webhook subscription that pushes grant-change events matching a filter. Cost: $0.20 USDC via x402 (paid by the agent runtime). On 402 response, agent must satisfy payment and retry.
  • verify_receipt Return LocalGov.jp's Ed25519 public key (for offline citation-receipt verification). Callers verify receipt signatures using WebCrypto with this key.
  • find_practitioner Recommend 3 Japanese licensed practitioner types (行政書士 / 税理士 / 中小企業診断士 / 社労士) for the grant's category. Returns role explanations and official-association registry links. **Informational only** — LocalGov.jp does NOT broker, refer, or accept commission for these recommendations.
