Get an API key

Free, immediate, and no account. Give an address you can receive mail at, confirm it, and the key is shown on the next page.

Where the confirmation link goes, and the only address we would use to tell you your sync has started failing.

A label for your key, so it is recognizable later. It does not have to be unique and it grants nothing.

Only useful if you need more than the default rate limits — say so here and it is a starting point rather than a fresh conversation.

The underlying IRS filings are public domain, and this database is published under the Open Database License (ODbL) v1.0. You are asked to credit the source and to share alike if you redistribute the database itself.
