Custom Implementation of the Tracing API

[FlorianW]

Hey OpenAI Dev Community,

I was just looking into the Python Agent’s SDK and noticed there’s an implementation for a new (?) tracing API (https://api.openai.com/v1/traces/ingest). I’m currently building an AgentLoop SDK for PHP. Since this specific API doesn’t appear to be officially documented yet, I wanted to check with you if you think it be okay for me to also implement this tracing functionality on the PHP side?

I’d appreciate your thoughts or any guidance on this!

Thanks you very much

Yes please!

Was surprised to find out this isn’t a top-level API in the documentation. We’d love to move over to ResponsesAPI, but as we’re not using Python…

More information would be greatly appreciated!

Hi Jim,

thanks for reaching out. Im actually in the process to build up my startup (assistant-engine.com) and release most of my code on the way as open source. Right now Im adapting everything to Responses API:

• For this I created an experimental SDK to already have all Features available to build on top of it: GitHub - AssistantEngine/php-openai-client: Experimental PHP client for OpenAI’s new Responses API
• I created a few primitives to handle LLM Calls much easier (GitHub - AssistantEngine/open-functions-core: Powerful primitives that simplify LLM calling - developed by Assistant Engine.) where you have a common abstraction for MessageLists (soon ItemList ) and Function Calling via “Open Functions” (MCP for PHP kind of). I already released Integrations for Slack, Notion etc → Right now Im making this Responses API compatible
• Next thing is to release the AgentLoop which will work with Completions and Responses API, makes use of the core abstractions and has an Interface like:

    /**
     * Runs the orchestration loop.
     *
     * Iterates until reaching max iterations, a stop condition is met, or an error occurs.
     *
     * @param string               $model
     * @param MessageList          $messageList
     * @param AbstractOpenFunction $openFunction
     *
     * @return MessageList The final message list after running.
     */
    public function run(string $model, MessageList $messageList, AbstractOpenFunction $openFunction): MessageList

I guess I have the updates ready within the next 1-2 weeks. Any Feedback would be highly appreciated on the way and will write an update if I released the AgentLoop as Open Source.
