Summary
Vercel introduced vercel curl, which accepts full URLs, hostnames, or linked-project paths and uses Vercel authentication to reach protected deployments. The feature lets developers test real deployment endpoints with native curl syntax instead of juggling separate bypass credentials or custom scripts.
What changed
Vercel added a vercel curl command that supports native curl syntax and authenticated access to protected deployments.
Why it matters
This pulls a common debugging and validation workflow into the platform CLI itself. For teams that rely on deployment protection, it shortens the path between shipping and verifying behavior in protected environments, and makes automated testing around secure deployments easier to script.
