## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability nero-labs-uk-business-trust-check-aecf4e56 -d '<json body>'
```

Example prompt: Can you run a trust check on 'Acme Electrical Ltd' at acme-electrical.co.uk, postcode LE11 2HP — I want to know if they're a legit registered UK company before I pay their invoice, including any insolvency notices and director checks.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
