What problem does it solve?

Writing Anthropic API integrations in C# can be error-prone and time-consuming when you need to correctly use SDK calls for messages, token counting, models, and file/beta features.

Core Features & Use Cases

  • C#-focused Anthropic API guidance: Covers core tasks like creating messages, counting tokens, listing models, and handling beta endpoints.
  • Streaming- and integration-oriented: Designed for implementing C# service code that interfaces with Anthropic capabilities such as streaming responses and structured workflows.
  • Fast method/type lookup: Encourages checking the references for exact methods and types before answering, reducing guesswork during implementation.

Real-world use case: A backend engineer building a C# assistant service that sends user prompts, optionally streams responses, checks token usage, and selects from available models programmatically.

Quick Start

Ask the AI to provide the correct C# method and request shape for creating an Anthropic Messages API request using the provided SDK references, including any required beta header usage.
