Test the email verification API before you wire it into production
Run a capped public demo check, then copy production-ready curl, JavaScript, or Python examples for authenticated Verifly verification. Use the OpenAPI spec for SDKs, agents, and ChatGPT Actions.

The demo endpoint is rate-limited for public testing. Use an API key for production, batch checks, CSV cleaning, and higher volume.
