What problem does it solve? Server-side routes and API endpoints are exposed to abuse such as request flooding, malicious bots, and invalid email signups, and developers often lack a clear workflow for adding protection. This skill guided the integration of Arcjet security rules into route handlers, but it is now deprecated in favor of the unified arcjet skill. ## Core Features & Use Cases - Route Protection: Adds rate limiting, bot detection, and abuse prevention to HTTP route handlers and API endpoints. - Email Validation: Integrates email validation checks into signup and form-handling code paths. - Deprecation Notice: This skill has been replaced by the unified arcjet skill, which covers HTTP routes plus non-HTTP code paths such as tool calls, MCP handlers, and queue workers. - Use Case: A developer protecting a Next.js or Express endpoint should invoke the arcjet skill instead to get current, framework-specific protection guidance. ## Quick Start Ask your AI agent to use the arcjet skill to add rate limiting and bot detection to your route handler.
