Validate an IBAN
Check an IBAN's country format, length and mod-97 checksum, and derive its country. A structural check — it does not prove the account exists.
price-ascending: candidates are ordered by the listed price of the operation, with no managed-first preference applied. Unlike /v1/apis, this surface does not rank Apiosk-settled listings above federated ones — a comparison that reorders on commercial grounds is not a comparison. Pass sort=managed_first for the catalog's ordering.
| Provider | Operation | Price | Settlement | Notes |
|---|---|---|---|---|
| Identifier Check | POST /validate/iban | $0.02 | via Apiosk | Fully offline check. |
| Financial Validation | POST /iban-country-check | $0.05 | via Apiosk | Can additionally assert an expected country via expected_country. |
Compared: listed price, settlement rail and input compatibility. Not measured yet: latency, reliability, result quality, and provider terms such as rate limits, jurisdiction and licensing.
