What this server can do
8 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.
compare_municipal_subsidies(category, max_municipalities, anchor_municipality_code)- Compare same-category subsidies across nearby municipalities (same prefecture by default). Useful for relocation / siting decisions. Free. Required: anchor_municipality_code.
find_practitioner(grant_id, industry_hint)- 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. Required: grant_id.
find_supplementary_grants(limit, prefecture, central_grant_id)- 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. Required: central_grant_id.
get_municipality_grants(limit, municipality_code)- 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. Required: municipality_code.
get_subsidy_detail(id)- 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. Required: id.
search_subsidies(sort, limit, offset, keyword, category, open_only, prefecture, min_amount_jpy, municipality_code)- Search Japanese central + municipal subsidies. Combine keyword (Japanese), prefecture, municipality_code, category, or minimum amount. Returns up to `limit` records. Free.
subscribe_changes(filter, ttl_days, hmac_secret, callback_url)- 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. Required: callback_url, hmac_secret, filter.
verify_receipt- Return LocalGov.jp's Ed25519 public key (for offline citation-receipt verification). Callers verify receipt signatures using WebCrypto with this key.

Signals
These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.
