### Validate User Registration

When a user signs up, check if their email is temporary:

```bash
EMAIL="newuser@example.com"
RESULT=$(curl -s -X POST https://antitempmail.com/api/v1/email/check \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $ANTITEMPMAIL_API_KEY" \
  -d "{\"email\": \"$EMAIL\"}")

IS_TEMP=$(echo $RESULT | jq -r '.isTemporary')

if [ "$IS_TEMP" = "true" ]; then
  echo "⚠️  Temporary email detected! Registration blocked."
else
  echo "✅ Valid email. Proceeding with registration."
fi
```

### Clean Email List

Filter out temporary emails from a list:

```bash
# Read emails from file (one per line)
EMAILS=$(cat email_list.txt | jq -R . | jq -s .)

curl -X POST https://antitempmail.com/api/v1/email/check/bulk \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $ANTITEMPMAIL_API_KEY" \
