A SWIFT code lookup API in Python posts an 8- or 11-character BIC and reads bank, city, and country. On BankDataStack that is POST /api/v1/swift/validate with header X-API-Key. Official sample: CHASUS33.
Starter is $49.99/mo (1,000 calls then $0.002) with a 7-day trial. IBAN / ABA are sibling POSTs. MCP host did not resolve on 17/9 — do not claim MCP live. Docs: /docs.
