Practical Applications

Technical Use Cases tag

monitor_heart

Refresh the whole book on a schedule

Post your customer or supplier list as a requests array and get a result back for each company. Diff company_status against your last run to catch strike-off, liquidation and dormancy across the portfolio.

hub

Backfill a legacy CRM or supplier master

Resolve years of free-text company records to canonical names, numbers and registered addresses in one pass. check_id carries your own row ID through to the response, so results map back to your database without matching on name.

book

Segment the book by risk

Aggregate sic_codes, incorporation dates and filing history across the portfolio to tier customers and size exposure. One request covers the batch instead of one call per company.

Trust & Assurance

Compliance & Security tag

Enterprise-grade infrastructure audited against the standards your regulators require.
