# List past lookups

Source: https://checkslip.com/en/docs/list-slip-checks

GET `https://api.checkslip.com/api/slips`

API key

The account's lookups, newest first. Pass trans_ref to see whether a slip was looked up before. Rows whose outcome is FOUND include the payer and payee names with masked accounts, for matching against your own order. Use next_cursor for the next page; there is no total. Needs an API key with slip:read.
