post/validate/v1/batch1 credit

Validate up to 100 mixed items ({type:vat|iban|email,value}) in one call.

Working example
Parameters

Up to 100 mixed validation items. Each is an object {type: vat|iban|email, value: <string>} (vat items may also carry a `country`). Each item is validated independently — a bad entry yields valid:false, it never fails the whole batch.

Whether to perform the live MX/DNS lookup (default true). Set false for a pure offline syntax+disposable check (no network, faster).
