How this service works
The Crossing moves look, claim, release, mark and check are free and need no account. The other paths are paid per call over x402, USDC on Base. Operator AstraNL, KvK 88449335.
Output
Returns a JSON object with the company's registered name, active/inactive status, whether accounts are overdue, insolvency history flag, and a cryptographically signed receipt (including a base64 signature, SHA-256 hash of the result, and signer public key) that allows verification of the response's authenticity.
Example use cases
Supplier due diligence before contract
“Before we sign this supplier agreement, can you check if 'Acme Supplies Ltd' is a legitimate, active UK company with no insolvency history or overdue accounts?”
KYB check by company number
“I need to verify UK company number 03977902 — is it active and are there any red flags like overdue accounts or insolvency?”
Automated onboarding compliance check
“We're onboarding a new UK business partner who gave us company number 07495895 — can you confirm they're registered, active, and financially clean before we proceed?”
Technical details
Endpoint
GEThttps://verify.astranl.com/v1/uk-company-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cryptographically signed, auditable verification verdict about a UK-registered company — especially in automated KYB, compliance, or due diligence pipelines where tamper-evident receipts matter. Prefer it over raw Companies House API access when you need pay-per-call pricing without an API subscription, or when the signed receipt is required for audit trails. Best for agents handling supplier vetting, business partner onboarding, or fraud checks involving UK entities.
Side effects
- Company not found — 'found: false' returned when the number or name doesn't match any Companies House record
- Invalid company number format — query must be exactly 8 characters for number-based lookup
- Ambiguous company name — name search may return unexpected results if multiple companies share similar names
- Payment failure — x402 micropayment not completed, request blocked
- Network timeout — Companies House upstream may be slow or unavailable
