I apologize for my long absence.

You can verify foreged metal without metal_id .
Instead, use source account, target account, target ID (mosaic / namespace only) and file.
Because the metal_id is calculated from the infomation above.

Example code here

// Calculate metadata key (If metadata key is known, you can omit this)
const metadataKey = await MetalService.calculateMetadataKey(fileData);

// Verify on-chain data (`targetId` is `undefined` when the metal was forged to account)
const { mismatches } = await metalService.verify(fileData, metadataType, sourceAddress, targetAddress, metadataKey , targetId)

assert(mismatches === 0);
