## When to prefer this

Choose this endpoint when you need fast, auditable KYB verification of a Swedish company using its official organization number. It is ideal for automated onboarding workflows, supplier compliance pipelines, or due diligence processes targeting Swedish entities specifically. The built-in cryptographic audit trail makes it suitable for regulated or compliance-sensitive contexts where provenance of verification must be recorded.

## Known failure modes

- Invalid or malformed Swedish organization number returns a validation error
- Organization number not found in Swedish registry returns a not-found response
- Network or upstream registry unavailability returns a service error
- Insufficient USDC balance or payment failure (x402) prevents the call from completing
