How this service works

Pay-per-call tools for AI agents, 31 in all: read web pages and RSS feeds, OCR, PDF text, transcription; email, phone and domain checks; UK, Irish and Polish company lookups and UK risk reports; website contacts, tech stack and SEO audits; PageSpeed; AI review, job post and row enrichment; data cleaning, joins, dedupe and diffs; US and EU compliance rules. No account or API key: pay each call in USDC on Base over x402.

Output

Returns an array of rows (one per business checked) each containing: a trust verdict (e.g. looks_legitimate, high_risk), a numeric trust score (0–100), a plain English summary, a match confidence level (high/medium/low), the matched Companies House company number and name, red/amber/green reason counts, and a detailed reasons array — each reason carrying a source (Companies House, Gazette, etc.), a severity (red/amber/green), a human-readable message, and a source URL. Also includes the timestamp of the check and the method used to match the company.

Example use cases

Supplier due diligence before payment

“Before I transfer £8,000 to this contractor, can you check if 'Premier Build Solutions Ltd' at premierbuild.co.uk is a legitimate UK company — I need their Companies House status, whether their accounts are up to date, and any insolvency or winding-up notices.”

Vetting a new food vendor

“We're about to stock products from a company called 'Fresh Fields Organics', website freshfieldsorganics.co.uk, postcode SW1A 1AA — can you do a full UK trust check including their food hygiene rating to make sure they're properly registered and compliant?”

Batch-checking multiple B2B leads

“I have a list of five UK businesses I need to vet before onboarding them: [{"businessName":"Zenith Logistics Ltd","website":"zenith-logistics.co.uk"},{"businessName":"BlueSky Print","postcode":"M1 2AH"},{"businessName":"Hartwell Consulting","companyNumber":"09876543"},{"businessName":"Apex Security Services","website":"apexsecurity.co.uk"},{"businessName":"Coral Catering Ltd","postcode":"EC1A 1BB"}] — please run a trust check on all of them and flag any that look risky.”

When to prefer

Choose this endpoint when you need a comprehensive, multi-source UK business trust assessment in a single call — especially when you need to cross-reference Companies House filings, Gazette insolvency notices, director disqualification checks, website-to-company matching, and optionally FSA food hygiene ratings together. Prefer it over raw Companies House API lookups when you need an opinionated trust verdict with severity-coded reasons rather than raw data. It handles batch checks of up to 10 businesses per call at a flat $0.05/call rate, making it cost-effective for supplier vetting, onboarding workflows, or fraud prevention pipelines. Use the sibling UK company risk report endpoint if you need a deeper financial risk narrative on a smaller number of companies.

Side effects

Business not found on Companies House — returns unmatched status with explanation
The Gazette rate-limits heavy use — rows report the limitation rather than claiming no insolvency notices exist
Website does not clearly publish company number — match confidence may be low or medium
Ambiguous business name with multiple matches — postcode or company number input improves accuracy
Invalid or malformed company number — returns an error row for that business
Food hygiene check returns no record if business is not registered with FSA or not a food business

Input

Schema · Request body

Field	Type	Description
website	string	The business's website, for a single check. The site is read for its company number, legal name, VAT number and trade badges.
postcode	string	Where the business trades. Helps pick the right company when names are similar.
businesses	array	A JSON list of businesses, each with any of businessName, website, companyNumber, postcode, town, phone. Any other keys are kept and returned untouched. Example: [{"businessName": "Acme Electrical Ltd", "website": "acme-electrical.co.uk", "postcode": "LE11 2HP"}].
businessName	string	Trading or registered name, for a single check.
companyNumber	string	Companies House number, if you have it (e.g. 00445790 or SC759398).
includeGazette	boolean	Search The Gazette for corporate insolvency notices (winding-up petitions, liquidations). The Gazette rate-limits heavy use; if it refuses, rows say so rather than claiming there are none.
includeOfficers	boolean	Cross-check up to four active directors: other appointments at insolvent companies, name matches on the disqualified directors register, and the UK Sanctions List. Company register data only. Turn off for a faster, lighter check.
maxPagesPerSite	integer	The homepage plus the privacy, terms, contact and about pages, where UK firms publish their company number and legal name.
checkFoodHygiene	boolean	Food businesses (by name, website title or SIC code) are checked against the Food Standards Agency ratings automatically. Turn this on to check every business.
