Use this section for Claude-native message payloads, multi-turn context, multimodal input, and tool calling.
  • Authenticate with x-api-key and anthropic-version
  • system is a top-level field rather than a message inside messages[]
  • messages[].content uses content blocks and should not be flattened too early
  • Tool use requires explicit tools, and later turns must send back tool_result blocks
