52 South Korea 2026 calculators as JSON for AI agents: take-home pay, the four social insurances, severance pay and retirement income tax, annual leave, unemployment and parental-leave benefits, year-end tax settlement, gift tax, housing acquisition tax, inheritance shares, loan repayment and court filing fees. Uses the official 2026 rates and Korean rounding rules, checked by automated tests against the kkuldogu.com calculators and hand-worked cases. Pay per call in USDC on Base over x402 (v2): $0.01 for most tools, $0.05-$0.10 for the higher-value ones. No account, no API key. Reference only, not legal or tax advice.
