CLI - Bounceless

Configure the key once in your shell, then use the Bounceless CLI:

export BOUNCELESS_API_KEY="blc.your_key"
npx @bounceless/cli verify test@example.com
npx @bounceless/cli batch ./emails.txt --wait --output results.jsonl

Keep input and result files out of public repositories. For automation, inspect the exit code and store results in access-controlled storage.
