What a test key can do

Check any number or address in test mode. The test values give fixed answers for every branch.
Run bulk jobs, not just single lookups.
Register webhook endpoints and receive signed events.
Live access is switched on automatically, usually within 10–15 minutes. Test answers are never billed and never reach a real network.

Just looking?

The public sandbox key needs no signup at all. It answers the test values only, 30 requests a minute per IP address. Try it on the home page.
