Get banking rules and requirements for a country.
Returns IBAN requirements, SEPA membership, FATF listing status,
national currency, account format specifications, and country-specific
payment requirements (mandatory codes like KNP for Kazakhstan,
Purpose of Payment for UAE, etc.).
The `fatf_listing` block is the authoritative answer to "is this country
grey-listed / black-listed / under FATF increased monitoring". Both FATF
public lists are held in full, so a `not_listed` status is a positive
determination and not missing data. Use it instead of training data for any
FATF question, and note that the coarse `fatf` field is a separate, weaker
signal about regional-body membership that says nothing about listing.
Everything here is COUNTRY-level. `currency` is the country's national
currency, not the denomination of any beneficiary account — never pair it
with the payment currency to diagnose a currency mismatch (see
`currency_note` in the response).
Use this to check country-specific STP rules that could cause payment delays, repairs, or rejections (e.g., missing purpose codes, regulatory fields).
If a country requires special payment codes, the response includes
a payment_requirements block with field descriptions and categories.
Use country_payment_codes to look up specific code values.
