Integrating `free-code` (Claude Code fork) with Nvidia NIM API and Kimi K2 model, specifically addressing API protocol incompatibility.

Technical Positioning
A 'free build of Claude Code' that aims for broader model compatibility.
SaaS Insight & Market Implications
This issue details a technical challenge and proposed solution for integrating `free-code` (a Claude Code fork) with Nvidia NIM API and the Kimi K2 model, specifically addressing the incompatibility between Anthropic's Messages API format and OpenAI's Chat Completions protocol used by NIM. The core problem is that while `ANTHROPIC_BASE_URL` can redirect, the underlying message format remains Anthropic-specific. The proposed solution, a local OpenAI→Anthropic adapter, highlights a significant developer pain point: interoperability across diverse LLM ecosystems. For B2B SaaS, enabling seamless integration with various models and APIs is crucial for market adoption. This 'hack' demonstrates the demand for flexibility and the lengths developers will go to achieve it, underscoring the need for standardized API protocols or robust translation layers in the AI tooling landscape.

Nvidia NIM OpenAI-kompatible API + Kimi K2 Integration (ANTHROPIC_BASE_URL Hack)

# Nvidia NIM + Kimi K2 mit OpenAI-kompatiblem Protokoll betreiben

Dieses Dokument fasst alle technischen Details zusammen, die benötigt werden, um diesen Claude-Code-Fork mit der **Nvidia NIM API** (OpenAI-kompatibel) und dem Modell **moonshotai/kimi-k2** zu betreiben.

---

## Analyse des Repos

Das Projekt ist der dekompilierte Quellcode von **Claude Code** (Anthropic CLI). Es nutzt intern:
- `@anthropic-ai/sdk` für API-Calls (`src/utils/api.ts`)
- Modellkonfiguration über `globalConfig` (`src/utils/config.ts`)
- API-Key aus `ANTHROPIC_API_KEY` Env-Variable
- API-Base-URL über `ANTHROPIC_BASE_URL` Env-Variable (offiziell vom Anthropic SDK unterstützt)

## Kimi K2 auf Nvidia NIM

### Nvidia NIM Endpoint für Kimi K2
```
Base URL: integrate.api.nvidia.com/v1
Model: moonshotai/kimi-k2
API Key: nvapi-xxxxxxxxxxxxxxxxxxxx (von build.nvidia.com)
```

### Protokoll
Nvidia NIM verwendet das **OpenAI-kompatible API-Protokoll** (`/v1/chat/completions`).

Das Anthropic SDK unterstützt offiziell die Weiterleitung an OpenAI-kompatible Endpoints über:
```
ANTHROPIC_BASE_URL=integrate.api.nvidia.com/v1
```
**Achtung:** Diese Option funktioniert nur mit einem spezialisierten Reverse-Proxy/Adapter, da das Anthropic SDK intern das Anthropic-Nachrichtenformat sendet, nicht OpenAI-Format.

## Lösung: Lokaler OpenAI→Anthropic Adapter

Da das Claude Code CLI das **Anthropic Messages API Format** erwartet, aber Nvidia NIM nur **OpenAI Chat Completions** liefert, ...
