Technical details
Endpoint
POSThttps://api.strale.io/x402/solutions/invoice-verify-ukWhen to prefer
Use this endpoint when you need to validate a UK supplier invoice before approving payment, especially when you want cross-checks across company registration, VAT, banking details, and sender identity in a single call with an audit trail. Prefer this over manual checks or generic company lookup endpoints when fraud detection across multiple invoice fields is required.

- Malformed IBAN or BIC causes field-level error
- Company number required but missing causes 400 bad request
- UK Companies House API unavailable causes downstream error
- VAT number format mismatch returns validation warning
- Sender domain not resolvable returns inconclusive result
