Streaming via SSE allows you to receive Claude API responses incrementally. Use the streaming parameter in your API request to get token-by-token output, reducing latency and enabling real-time chat experiences in Node.js, Next.js, or Cloudflare Workers.

Yes, Claude's vision capabilities support image understanding and multi-image workflows. Pass image data to the API alongside text prompts to analyze visual content, extract information, and process multiple images in a single request.

Tool calling patterns enable Claude to request structured actions. Define tools with JSON schema, pass them to the API, and handle Claude's tool-use requests by executing the specified function and returning results—enabling error recovery and complex workflows.

Rate limit errors (429), overloaded_error, and invalid_request_error require handling strategies. Implement exponential backoff, retry logic, and error recovery patterns in your deployment—templates for Node.js, Next.js, and Cloudflare Workers provide production-ready implementations.

Prompt caching stores frequently reused context, reducing tokens and cost. Cache system prompts, large documents, or conversation history to avoid reprocessing identical input blocks across multiple API calls.

Yes, deployment scaffolds support Cloudflare Workers, Next.js API routes, and Node.js environments. Choose templates matching your platform to build production-ready chatbots, AI assistants, and content tools with streaming, tool use, and error handling.
