You can now use native curl syntax with the Vercel CLI. The vercel curl command accepts full URLs, bare hostnames, and the --url flag, and uses your Vercel auth to bypass Deployment Protection.
vercel curl https://example.vercel.app/api/hello
vercel curl example.vercel.app/api/users -X POST -H "Content-Type: application/json" -d '{"name":"Ada"}'
vercel curl --url https://example.vercel.app/api/status --compressed
URL-based invocations against any deployment
If you've linked a project, you can also pass just a path:
vercel curl /api/hello
vercel curl /api/users -X POST -d '{"ok":true}'
Path-based invocations against the linked project
Update to the latest Vercel CLI version and run vercel curl to get started. Learn more in the Vercel CLI documentation.
