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).
Example use cases
Supplier onboarding compliance screening
“Before we onboard these five UK suppliers, can you check their Companies House numbers — 00445790, SC234567, OC112233, 04444444, 09876543 — and tell me which ones are active and which have any warnings or cautions?”
Investment portfolio company health check
“I have a list of UK portfolio companies: 10000001, 10000002, 10000003, 10000004. Can you run a batch check on all of them and let me know their current status and whether any are flagged?”
Fraud risk screening before contract signing
“We're about to sign contracts with three UK firms — numbers 07654321, SC999888, OC445566. Can you verify all three at once and highlight any that are dissolved or have compliance warnings?”
Technical details
Endpoint
GEThttps://verify-uk.verifyuk.workers.dev/v1/business/batch?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
