+### JWT Authentication (Required for Advanced Features)
+
+**Some endpoints require JWT authentication (expires every 5 minutes):**
+
+```ruby
+# Authenticate to get JWT token
+client.authenticate(
+  email: 'your_email@example.com',
+  password: 'your_password'
+)
+# Token is automatically stored and injected in subsequent requests
+
+# Check token status
+client.jwt_expired? # => false
+client.jwt_time_remaining # => 287 (seconds)
+
+# JWT is required for these endpoints:
+# - Mass Payouts (create_payout, verify_payout, list_payouts)
+# - Conversions (create_conversion, conversion_status, list_conversions)
+# - Custody Operations (transfer_between_sub_accounts, write_off_sub_account_balance)
+# - Recurring Payments (delete_recurring_payment)
+
+# Example: Create payout (requires JWT)
+client.authenticate(email: 'your@email.com', password: 'password')
+payout = client.create_payout(
+  withdrawals: [
+    {
+      address: 'TEmGwPeRTPiLFLVfBxXkSP91yc5GMNQhfS',
+      currency: 'trx',
+      amount: 10
+    }
+  ],
+  payout_description: 'Weekly payouts'
+)
+
+# Verify payout with 2FA code (from Google Authenticator)
+client.verify_payout(
+  batch_withdrawal_id: payout['id'],
+  verification_code: '123456'
+)
+
+# Token auto-refresh pattern
+def ensure_authenticated(client, email, password)
+  return unless client.jwt_expired?
+  client.authenticate(email: email, password: password)
+end
+
+# Before JWT-required operations
+ensure_authenticated(client, EMAIL, PASSWORD)
+payouts = client.list_payouts(limit: 10, offset: 0)
+
+# Clear token when done (optional, for security)
+client.clear_jwt_token
+```
+
+**See [examples/jwt_authentication_example.rb](examples/jwt_authentication_example.rb) for complete usage patterns.**
+
+### Currency Conversions (JWT Required)
+
+**Convert between cryptocurrencies at market rates:**
+
+```ruby
+# Authenticate first
+client.authenticate(email: 'your@email.com', password: 'password')
+
+# Create conversion
+conversion = client.create_conversion(
+  from_currency: 'btc',
+  to_currency: 'eth',
+  amount: 0.1
+)
+# => {"conversion_id" => "conv_123", "status" => "processing", ...}
+
+# Check conversion status
+status = client.conversion_status(conversion['conversion_id'])
+# => {"status" => "completed", "from_amount" => 0.1, "to_amount" => 2.5, ...}
+
+# List all conversions
+conversions = client.list_conversions(limit: 10, offset: 0)
+```
+
+### Fiat Payouts (Beta - JWT Required)
+
+**Withdraw cryptocurrency to fiat bank accounts:**
+
+```ruby
+# Authenticate first
+client.authenticate(email: 'your@email.com', password: 'password')
+
+# Get available payment methods
+methods = client.fiat_payout_payment_methods(fiat_currency: 'EUR')
+# => {"result" => [{"provider" => "transfi", "methods" => [...]}]}
+
+# Create payout account
+account = client.create_fiat_payout_account(
+  provider: 'transfi',
+  fiat_currency: 'EUR',
+  account_data: {
+    accountHolderName: 'John Doe',
+    iban: 'DE89370400440532013000'
+  }
+)
+# => {"result" => {"id" => "acc_123", ...}}
+
+# Get conversion rates
+rates = client.fiat_payout_rates(
+  crypto_currency: 'btc',
+  fiat_currency: 'EUR',
+  crypto_amount: 0.1

+# => {"result" => {"fiatAmount" => "2500.00", "rate" => "25000.00", ...}}
+
+# Create fiat payout
+payout = client.create_fiat_payout(
+  account_id: account['result']['id'],
+  crypto_currency: 'btc',
+  crypto_amount: 0.1
+)
+# => {"result" => {"id" => "payout_123", "status" => "PENDING", ...}}
+
+# Check payout status

+  status: 'FINISHED',

 ### Webhook Verification (Critical!)
 
 **Always verify webhook signatures to prevent fraud:**
