Web requests in Grasshopper are here!

Swiftlet is a general-purpose HTTP client for Grasshopper - essentially cURL for your definitions.

Send any HTTP request (GET, POST, PUT, PATCH, DELETE) to any API endpoint with full control over headers, query parameters, and authentication (Basic, Bearer, OAuth 2.0, API keys). Parse JSON, XML, and HTML responses with built-in components for navigating and extracting data.

Beyond client requests, Swiftlet also provides server-side capabilities: build HTTP APIs with Server Components, enable real-time communication with WebSockets and UDP, and expose Grasshopper tools to AI clients via MCP (Model Context Protocol).
