Technical details
Endpoint
GEThttps://api.strale.io/x402/uk-company-data?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need official UK Companies House data for a specific company, including verification of active status, registered address, or SIC codes. Prefer over generic web search when you need authoritative, structured company registry data for due diligence, compliance, or enrichment workflows. Use the company_number field for precise lookups; use company_name for fuzzy discovery.
Side effects
- Company number not found — invalid or non-existent 8-digit number
- Fuzzy name search returns no matches or ambiguous results
- Rate limiting or payment failure via x402 protocol
- Companies House API upstream unavailability
- Malformed company number format (not 8 digits)
