can you support custom base api url

[winezer0]

Could you set a custom base API URL in the command line or environment variables?

rust-genai Already Allow customizing URLs

examples : https://github.com/jeremychone/rust-genai/blob/main/examples/c06-target-resolver.rs

// -- Build an auth_resolver and the AdapterConfig
let target_resolver = ServiceTargetResolver::from_resolver_fn(
|service_target: ServiceTarget| -> Result<ServiceTarget, genai::resolver::Error> {
let ServiceTarget { model, .. } = service_target;
let endpoint = Endpoint::from_static("https://api.x.ai/v1/");
let auth = AuthData::from_env("XAI_API_KEY");
let model = ModelIden::new(AdapterKind::OpenAI, model.model_name);
// TODO: point to xai
Ok(ServiceTarget { endpoint, auth, model })
},
);

Custom API base URL functionality has been successfully implemented!

🎯 Features Added

1. CLI argument support: --api-base-url <URL>
2. Environment variable support: API_BASE_URL
3. Priority: CLI argument > environment variable
4. OpenAI compatibility: Automatically treats custom base URLs as OpenAI-compatible

📝 Usage Examples

# CLI argument
parsentry --repo owner/repo --api-base-url "https://custom.api.example.com/v1"

# Environment variable
API_BASE_URL="https://custom.api.example.com/v1" parsentry --repo owner/repo

# OpenRouter example
OPENAI_API_KEY=$OPENROUTER_API_KEY parsentry \
  --root ./your-code \
  --api-base-url "https://openrouter.ai/api/v1" \
  --model "openai/gpt-3.5-turbo"

🔧 Technical Details

• ServiceTargetResolver: Uses genai crate's resolver system for custom endpoints
• Adapter forcing: Forces AdapterKind::OpenAI for custom base URLs to ensure OpenAI-compatible API compatibility
• Model name preservation: Maintains original model names for API compatibility
