🟢list_tax_rules(category, taxpayer, tax_year)
FREE — returns structured rules. Catalog of machine-readable Japanese crypto-asset tax rules (rules-as-code): titles, status (current / enacted_pending), effective dates and statutory citations, filterable by category, taxpayer and tax_year. tax_year resolves the current-vs-2028-reform epoch per rule (applies / pending_enforcement). Sources are public only (NTA FAQ, e-Gov statutes, MOF documents); not tax advice. 一般的な税制情報の提供であり、個別の税務判断は税理士にご相談ください。

}🟢get_rule_pack(scenario)
Scenario-curated bundle of full structured rules (statements, citations, parameters) for one use case: defi_staking | overseas_exchange | corporate_holding | transition_2028. Paid via x402: each call costs 0.05 USDC. This tool returns the HTTP 402 payment challenge (spec-conformant accepts list) for the pack resource. The 402 is real: settle it against /v1/packs/{scenario} with an X-PAYMENT header and the 200 response delivers the full pack body ({status:"settled", settlement, pack}) — payment buys the actual structured rules, not a receipt.
