How this service works
Company data, compliance checks, financial validation. Structured JSON with audit trails. Every capability independently quality-scored.
Output
Returns structured JSON with verification results for each invoice field (CVR validity, IBAN/BIC match, VAT status, domain/email alignment with company registration), plus an overall trust assessment and an audit trail of checks performed.
Example use cases
Pre-payment fraud screening for suppliers
“I just received an invoice from a Danish vendor claiming to be TechSolutions A/S. Can you verify their CVR number 29384756, check that their IBAN DK9520000123456789 and BIC NORSKKK are real, and confirm the invoice actually came from their registered email address? I need to make sure this isn't a fake invoice before we process payment.”
Bulk invoice validation for accounting teams
“We've got five invoices from different Danish suppliers this week. Instead of checking each one manually, can you validate all their CVR numbers, IBANs, VAT registrations, and confirm their sender domains match what's officially registered? I want a full audit trail so we can document our compliance checks.”
Due diligence on new business partner
“We're about to sign a contract with a Danish company called Grøn Industries. Before we commit, can you verify their CVR, check their IBAN and BIC details, validate their VAT number, and make sure the company website and contact email are consistent with their official registration? I want confidence that they're a legitimate, compliant business partner.”
Technical details
Endpoint
POSThttps://api.strale.io/x402/solutions/invoice-verify-dkWhen to prefer
Use this endpoint when you need to validate a Danish business invoice end-to-end — combining CVR company registry lookup with IBAN/BIC financial validation, VAT verification, and sender identity checks in a single call with an audit trail. Prefer this over generic company lookup endpoints when the use case is specifically invoice fraud prevention or pre-payment due diligence on a Danish supplier.
Side effects
- Invalid or non-existent CVR number returns a validation error
- IBAN checksum failure or mismatch with Danish registry
- BIC not recognized or mismatched with IBAN bank
- VAT number format invalid or unregistered
- Domain or email cannot be traced to the registered company
- Upstream Danish CVR registry unavailable causing timeout
