Reverse SSI lookup — find banks that use a given correspondent for a currency.
Given a correspondent BIC, currency, and origin country, returns the banks
in that country that have a declared nostro at the correspondent for that
currency. Inverse of ssi_lookup.
Returns only swift + name per bank — to retrieve the account number,
intermediary chain, or other SSI details for a specific bank from the
result list, call ssi_lookup(bank_swift, currency) on it.
Country and currency are required (not optional) — both bound the result
set and the query is rejected without them.
Requires an API key with an active PRO, VIP, or FI subscription.
Tight per-account daily caps apply (5/day on PRO, 10/day on VIP/FI/trial).
Args:
correspondent_swift: BIC of the correspondent bank (e.g. "IRVTUS3N").
currency: ISO 4217 (e.g. "USD").
country: ISO 3166-1 alpha-2 of the client banks (e.g. "AE").
name_prefix: Optional prefix on bank name (e.g. "AL").
page: 1–4. Defaults to 1.
api_key: Your Ohmyfin API key (prod-...). Can also be passed
via KEY header or Authorization: Bearer header.
Examples:
banks_using_correspondent("IRVTUS3N", "USD", "AE")
banks_using_correspondent("CITIUS33", "USD", "SA", name_prefix="AL")
