1. Email [hello@lookvalid.com](mailto:hello@lookvalid.com?subject=Get%20started%3A%20API%20key) with the lookups you need and roughly how many a month.
2. We set up your account and reply with your API key.
3. Write from the same address any time you need access again, a key revoked or a plan changed.

• The lookups you need: phone, email, domain or IP, or a mix.
• Roughly how many lookups you expect each month, and whether they arrive steadily or in large batches.
• How you plan to call them: the API from your own code, bulk CSV files, or an AI client through the MCP server.

Store the key in an environment variable or a secret manager, never in source control or browser code, and ask us to revoke it if it leaks. The API keys guide covers the details.

Follow the quickstart with your key.
