Custom provider headers

[ndaidong]

How to add some custom headers to the provider configs?
For example I use GoModel AI Gateway, it requires a "X-GoModel-User-Path" header.
Other require API key sent via a bearer authorization header.

@ndaidong Thanks for the issue. Currently, custom provider headers are not supported. But this is a very good point.

I will take a look and hopefully add the capability soon, and let you know.

@ndaidong I have released v0.24.4. The headers can be set through updating the config file: https://mochow13.github.io/keen-code/docs/ai-providers.html#custom-headers

Please check from your side and validate whether it works or not. Will close it once it works as expected. Thanks!

Thanks. It seems likely custom headers have been loaded. But I could not test if it works or not.
I have a GoModel AI gateway standing between the agents and AI providers.
Tried to set it up as an "openai" provider with custom base_url, but requests show 403 Forbiden.

{
  "active_provider": "openai",
  "active_model": "xiaomi/mimo-v2.5",
  "providers": {
    "openai": {
      "base_url": "https://<my-gateway.com>/v1",
      "api_key": "sk_*********************************",
      "headers": {
        "X-GoModel-User-Path": "/keencode"
      },
      "models": ["xiaomi/mimo-v2.5", "xiaomi/mimo-v2.5-pro"]
    }
  }
}

@ndaidong So you expect this to work as expected and not throw 403? Or you mean you couldn't test actual integration but tried to set up a dummy provider with headers?

[ndaidong]

I setup a real provider (my AI gateway) under the name "openai" (because keen does not support custom provider name yet).
Just want to see how it works but it doesn't.

@ndaidong Hmm that's a shame! The problem is I am unable to debug it myself since I don't have any gateway setup in place. Perhaps you can debug it and possibly raise an PR? Keen is open-source, so anyone can work on any issue.

The contribution guideline is here: https://github.com/mochow13/keen-code/blob/main/CONTRIBUTING.md

To debug, you can simply add some debug logs, run with KEEN_LOG_LEVEL=debug go run cmd/main.go and try to connect to your gateway. Then the logs can be found in the respective log file as mentioned in CONTRIBUTING.md.

Let me know if you can take a look! 🙏
