Up to 1,000 synthetic records. Generated email addresses use example.test and are not deliverable. SQL uses standard quoted identifiers and literals; review compatibility with your database. No database connection is made.

Use this tool from the API reference or connect through the SDK, CLI, SSH, or MCP. Hosted calls share your plan allowances.
