How this service works
The trust layer for AI agents — 250+ independently tested data capabilities across 27 countries. Execute capabilities via REST, MCP, A2A, or x402 micropayments. Every call returns an audit record with cryptographic chain hashing.
Output
Returns a structured validation result indicating whether each supplied field (IBAN, BIC, VAT number, Companies House number, sender email, sender domain, redirect URL) passes or fails verification, along with fraud risk indicators, an overall trust assessment, and a cryptographically hashed audit record for the call.
Example use cases
Accounts payable invoice fraud check
“Before we pay this invoice from a new UK supplier, can you run a full verification? Their email is billing@techsupplies-uk.com, domain techsupplies-uk.com, VAT GB987654321, Companies House 07654321, IBAN GB82WEST12345698765432, and BIC WESTGB22.”
Onboarding supplier due diligence
“We're onboarding a new UK vendor and just received their first invoice — please check that their Companies House number 04123456, VAT number GB456123789, and IBAN GB29MIDL40051512345678 all match up and look legitimate before we add them to our payment system.”
Suspicious invoice redirect link check
“I got an invoice that looks a bit off — the sender is payments@globalworks.co.uk with domain globalworks.co.uk and there's a redirect URL https://globalworks.co.uk/invoice-redirect, VAT GB111222333, Companies House 09876543, IBAN GB33BUKB20201555555555, BIC BUKBGB22. Can you verify if this is a real UK business and flag anything suspicious?”
Technical details
Endpoint
POSThttps://api.strale.io/x402/v2/solutions/invoice-verify-ukWhen to prefer
Choose this endpoint when you need to validate UK-specific invoices against multiple authoritative data sources simultaneously — including Companies House, HMRC VAT, and banking identifiers — in a single auditable call. Prefer it over generic VAT-only validators when invoice fraud detection across multiple fields (IBAN, BIC, domain, email, redirect URL) is required. The cryptographic audit chain makes it suitable for compliance-grade workflows where a verifiable record of the check is needed.
Side effects
- Invalid IBAN format returns field-level format error
- VAT number not found in HMRC registry returns unverified status
- Companies House number not matched returns entity mismatch
- Unreachable sender URL returns URL trace failure
- Missing required fields returns 400 validation error
- Payment not made or insufficient USDC balance returns 402 Payment Required
