How this service works
UK Companies House company-level counterparty preflight: status, RO, accounts/confirmation overdue → NORMAL|REVIEW|NOT_FOUND
Output
Returns a status string of NORMAL (company is active and filings are current), REVIEW (company has issues such as overdue accounts, overdue confirmation statement, dissolved status, or other red flags), or NOT_FOUND (company number does not exist in Companies House). May also include detail on registered office validity and specific overdue filing types.
Example use cases
Pre-onboarding supplier due diligence
“Before we add this new UK supplier to our vendor list, can you run a counterparty preflight on company number 09876543 and tell me if they're NORMAL or if anything flags them for REVIEW?”
Automated KYB check for fintech onboarding
“A new business customer just signed up with UK company number 04155721 — can you check their Companies House status, confirm they're active, and flag if accounts or confirmation statements are overdue?”
Investment target compliance screen
“We're considering investing in a UK company with registration number 07654321 — can you run a preflight check to see if they're in good standing or if there are any compliance red flags like overdue filings?”
Technical details
Endpoint
GEThttps://138-197-9-7.sslip.io/v1/uk_company_counterparty_preflight?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, single-call preflight risk signal for a UK-registered company before initiating a business relationship, payment, or onboarding flow. It is ideal for automated KYB pipelines, supplier screening, and investment due diligence where you need a simple NORMAL/REVIEW/NOT_FOUND verdict rather than raw Companies House data. Prefer this over direct Companies House API calls when you want a pre-interpreted risk signal with overdue filing detection already handled.
Side effects
- NOT_FOUND returned when company number does not exist or is malformed
- REVIEW status returned for companies that are dissolved, struck off, or have overdue filings
- API may return errors if Companies House upstream is unavailable
- Payment required error (402) if x402 payment header is missing or insufficient
- Invalid company number format may result in error or NOT_FOUND
