Perplexity

Terminal-based VAT checks

Run `validate_eu_vat` directly from your shell to verify tax IDs during your CI/CD process. It pipes the output into your logs for immediate audit trails. This keeps your validation logic headless and fast. You get the raw response data without any UI overhead.

Batch audit your pipelines

Use `validate_multiple_vat` to scan entire CSV or JSON files during your deployment scripts. It validates hundreds of IDs in seconds. It is designed for high-concurrency tasks where speed matters. You can trigger it as part of a cron job.

Monitor VIES availability

Add `check_api_status` to your health check scripts to ensure your pipeline doesn't break. It returns a boolean that you can use to gate your deployments. You gain visibility into the external gateway state. It prevents false negatives caused by VIES maintenance.
