# Instrument Screening

> Screen bank accounts, crypto wallets, cards, and IBANs through one normalized instrument object.

Use `instrument_screening` when a payment instrument is added or evaluated.

Required:

| Field                                                      | Requirement                                        |
| ---------------------------------------------------------- | -------------------------------------------------- |
| `use_case`                                                 | Must be `instrument_screening`                     |
| `entity.type`                                              | `person` or `business`                             |
| `instrument.type`                                          | `bank_account`, `crypto_wallet`, `card`, or `iban` |
| Matching instrument payload or `instrument.vault_token_id` | One is required                                    |

The nested payload must match `instrument.type`. For example, `instrument.type: "crypto_wallet"` must use `instrument.crypto_wallet`, not `instrument.bank_account`.
