compare_municipal_subsidiesread-only | Compare same-category subsidies across nearby municipalities (same prefecture by default). Useful for relocation / siting decisions. Free. |
find_practitionerread-only | 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. |
find_supplementary_grantsread-only | 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. |
get_municipality_grantsread-only | 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. |
get_subsidy_detailread-only | 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. |
search_subsidiesread-only | Search Japanese central + municipal subsidies. Combine keyword (Japanese), prefecture, municipality_code, category, or minimum amount. Returns up to `limit` records. 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_receiptread-only | Return LocalGov.jp's Ed25519 public key (for offline citation-receipt verification). Callers verify receipt signatures using WebCrypto with this key. |
