Anthropic Claude API
Integrate Anthropic Claude AI models into your Delphi applications for advanced chat, analysis, content generation, vision and tool use.
Integrate Anthropic Claude AI models into your Delphi applications for advanced chat, analysis, content generation, vision and tool use.
Typed Delphi/C++Builder client for the Anthropic Messages API — streaming, tool use, vision, extended thinking, prompt caching, files and MCP-on-Claude.

Set ApiKey on AnthropicOptions, then call CreateMessage for typed requests or use _CreateMessage / _CreateMessageStream JSON-string shortcuts.

CreateMessage accepts a typed TsgcAnthropicClass_Request_Messages and returns a parsed response. _CreateMessage, _CreateMessageWithSystem, _CreateMessageStream and _CreateMessageWithThinking are JSON-string shortcuts.
Build TsgcAnthropicClass_Request_Tool entries to expose function-calling tools to Claude. _CreateMessageJSON applies an inline JSON schema for structured outputs.
Attach images and PDFs as content blocks — _CreateVisionMessage and _CreateDocumentMessage handle the base64 framing and the document content type.
Toggle thinking on the request to enable Claude's extended reasoning mode. _CreateMessageWithThinking and _CreateMessageWithAdaptiveThinking set the budget and surface thinking blocks.
Add cache_control: {type: ephemeral} to system or user blocks to cut repeat-prompt latency and cost. Hit/miss counters are returned in the response usage block.
Endpoints for the Files API, asynchronous Message Batches, server-side WebSearch tool and Claude-as-MCP-host are all exposed under the same component.
