POST/v1/validate/accounts
Resumen

Validate a batch of bank account identifiers. Each item declares its `country` (required) and optionally a `type` ∈ {cbu, cvu, clabe, cci, iban} — when omitted it is detected from the country and format. Verifies the right checksum per format: CBU (block Mod-10), CVU (same checksum, different prefix), CLABE (Banxico weighted digit), CCI (Peru), IBAN (Mod 97-10). Resolves `bank_code → bank_name` from official registries. Each result carries `valid`, `checksum_valid` and the resolved `bank_name` when available. Up to 1000 accounts per request.

Notas

Validates that the number is well-formed and belongs to a real bank — it does not confirm the account is open or who owns it, and never runs a test transfer. Separators (spaces, dashes, dots) are stripped; letters are uppercased for IBAN. CBU/CVU use the block Mod-10 checksum; CLABE uses the Banxico weighted digit. The envelope is shared by every endpoint: POST `{items:[…]}` (1–1000) → `{results:[…]}` correlated by `id`.
