## Re-check after onboarding

Companies dissolve, change name and change status. Monitoring re-checks a book of companies on a schedule so a dormant risk or a dissolved counterparty does not sit in your system unnoticed.

- Batch re-verify a whole book
- Compare status over time
- Flag the changed records

## Pay once a day, not once a call

The same company is billed at most once per day across all endpoints, so a nightly sweep that touches the same records does not multiply your bill.

- Daily dedup per company
- Free tier across the batch
- Per-item results and errors

## FAQ

### Do you send change events?

Monitoring works on demand or on your schedule: re-verify the book, compare the results, and act on the records that changed.

### How often should I re-check?

Match the cadence to your risk: monthly for most books, more often for high-value counterparties. The registers themselves refresh daily to weekly.
