How this service works
Paid data and decision APIs for autonomous agents, priced and settled entirely via the x402 v2 payment protocol (no API keys, no signup).
Output
A JSON object containing: a numeric risk score (0–100), a risk level label (e.g. LOW/MEDIUM/HIGH), a list of persons with significant control (PSC) with their natures of control, a list of officers with roles and appointment dates, recent filing history entries, a plain-English narrative summary of findings, a recommended action (e.g. STANDARD_CHECKS), and a disclaimer noting this is a public-data risk indicator only. Also includes the company number queried and the lookback period used.
Example use cases
Supplier onboarding risk check
“Before we onboard this UK supplier, can you pull a due diligence report on Companies House number 07654321 — I need the risk score, who the directors are, and any filing history red flags from the past 5 years?”
Investment target ownership investigation
“We're considering investing in a UK company with registration number 03210987 — can you find out who has significant control, what the directors look like, and give me an overall risk assessment?”
Fraud indicator check on counterparty
“I need to quickly check if company number 11223344 looks suspicious — can you get me their risk score, PSC details, and a summary of any filing anomalies from Companies House?”
Technical details
Endpoint
GEThttps://autoworker.stebilly6.workers.dev/services/uk-business-due-diligenceWhen to prefer
Choose this endpoint when you need a fast, structured, automated risk assessment of a UK-registered company using Companies House public data, especially in agentic workflows that require no API key signup and can settle micropayments via x402. It is ideal for supplier onboarding, counterparty checks, investment screening, or any compliance workflow needing PSC ownership, officer data, and filing history in a single call. Prefer it over manual Companies House searches when you need a machine-readable risk score and narrative summary rather than raw filings.
Side effects
- Company number not found in Companies House — returns an error or empty result
- Invalid or malformed company number format — API may return a validation error
- Companies House upstream data unavailable or rate-limited — may result in a timeout or degraded response
- Company exists but has no PSC or officer records — fields may be empty arrays
- Payment not settled via x402 — request will be rejected with a 402 Payment Required response
