# Card Tools

> BIN/IIN lookup, brand identification, Luhn validation, and card risk assessment.

The Card Tools endpoints let you retrieve card metadata, identify card brands, validate card numbers, and assess transaction risk - all from the card's BIN/IIN (the first 6 to 11 digits).

## Endpoints

<CardGroup cols={2}>
  <Card title="Brand Lookup" icon="credit-card" href="/api-reference/tools/brand-lookup">
    Identify the card brand and get the brand logo URL
  </Card>

  <Card title="Metadata Lookup" icon="magnifying-glass" href="/api-reference/tools/metadata-lookup">
    Get full card metadata: brand, type, category, issuer, country
  </Card>

  <Card title="Luhn Validation" icon="check" href="/api-reference/tools/luhn-validation">
    Validate a card number using the Luhn algorithm
  </Card>

  <Card title="Card Validation" icon="shield-check" href="/api-reference/tools/card-validation">
    Risk assessment using card BIN + payer billing/IP data
  </Card>
</CardGroup>

## Common Use Cases

* **BIN-based routing** - Use the metadata lookup to get the issuer country and route payments to the optimal PSP per region
* **Card form UX** - Use the brand lookup to display the card brand logo in real time as the user types
* **Fraud screening** - Use card validation to compare the card's issuer country against the payer's IP and billing address
* **Input validation** - Use the Luhn check to validate card numbers before submitting a payment
