# Verify UK – Batch Business Status Check

> Verify UK – Batch Business Status Check is a paid API for AI agents from verify-uk.verifyuk.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-30).

Checks up to 40 UK Companies House numbers in a single call, returning status, warnings, and cautions for each company.

## 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 verify-uk-batch-business-status-check-38de566b
```

Example prompt: Can you batch-check these UK company numbers for me — 12345678, SC123456, OC301234 — and flag any that are dissolved, have warnings, or look suspicious based on official Companies House data?

## When to prefer this

Use this endpoint when you need to verify multiple UK companies in a single API call rather than one at a time, saving cost and latency. Prefer it over single-company lookups when you have 2–40 company numbers to screen simultaneously, such as during supplier onboarding, due diligence, or portfolio reviews. It is ideal when you need a prioritised view with flagged companies surfaced first.

## Known failure modes

- Invalid or malformed company number returns not_found in results
- Exceeding 40 company numbers in one call may be rejected
- Payment failure (402) if USDC balance insufficient or x402 header missing
- Non-existent company numbers return not_found status rather than an error
- Rate limiting or worker timeout for very large comma-separated lists near the 40-item cap

## How this service works

Pay-per-call UK verification tools for AI agents: validators, business checks and website trust checks from official UK public data. Pay with USDC via x402 - no account, no API key.

## Output

Returns a JSON object with per-company results (company name, number, status such as active/dissolved, and counts of warnings and cautions), a list of flagged company numbers sorted first, and aggregate totals (total checked, clear, not found, with warnings, with cautions only).
