A BIN lookup API in Python posts the first digits of a card and reads brand, type, and country. On BankDataStack that is POST /api/v1/bin/validate with header X-API-Key. Official homepage BIN: 424242.
Starter is $49.99/mo (1,000 then $0.002) with a 7-day trial. There is no live MCP host (DNS for mcp.bankdatastack.com failed 17/9). Docs: bankdatastack.com/docs.

}This is not a “CC checker” and not an authorization. Gate UX on data.valid and cardBrand.
