 /**
- * Canonicalize address format
+ * Canonicalize an LTC or BCH address.
  *
- * Converts cryptocurrency addresses between different formats. This endpoint is specifically
- * designed for coins that support multiple address formats.
- *
- * **Supported Coins:**
- * - **Bitcoin Cash (BCH/TBCH)**: Converts between base58 and cashaddr formats
- * - **Bitcoin SV (BSV/TBSV)**: Supports base58 format only (cashaddr not supported)
- * - **Litecoin (LTC/TLTC)**: Returns address unchanged (included for API consistency)
- *
- * **Address Formats:**
- * - **base58**: Traditional Bitcoin-style addresses (e.g., '1BpEi6DfDAUFd7GtittLSdBeYJvcoaVggu', '3CWFddi6m4ndiGyKqzYvsFYagqDLPVMTzC')
- * - **cashaddr**: Bitcoin Cash address format with network prefix (e.g., 'bitcoincash:qpm2qsznhks23z7629mms6s4cwef74vcwvy22gdx6a')
- *
- * **BCH Behavior:**
- * - version='base58': Converts any input format to base58 canonical format
- * - version='cashaddr': Converts any input format to cashaddr format (adds network prefix if missing)
- * - Default (no version): Converts to base58 format
- *
- * **BSV Behavior (Deprecated):**
- * - version='base58': Converts address to base58 canonical format
- * - version='cashaddr': Not supported - will return error "unsupported address format cashaddr for network bitcoinsv"
- * - Default (no version): Converts to base58 format
- *
- * **LTC Behavior:**
- * - Returns the input address unchanged regardless of version parameter
- * - Included for API consistency but performs no transformation
- *
- * **Response:** Returns the canonical address string directly (as JSON string primitive).
