Anthropic API

API access to Claude model family including Claude 3.5 Sonnet, Haiku, and Opus. Excels at coding, analysis, long-context tasks, and safety-critical applications.

Claude Agent SDK

Anthropic's first-party agent SDK for building production agents on top of Claude. Native MCP support, sub-agents, tool use, and prompt caching out of the box. Routinely benchmarked alongside Strands, LangGraph, and the OpenAI Agents SDK in 2026 framework comparisons.
