FAQ
What counts as a result?
One document row.
Do I pay for searches with no results or for errors?
No. No-results, invalid-input, error and limit rows are free.
Where does the data come from?
From the public Federal Register API, published by the Office of the Federal Register (National Archives) and the U.S. Government Publishing Office. Lepidata is not affiliated with or endorsed by either.
Is there a start fee?
No. You pay only the flat price per result.
