fix: [Gap] OpenAI/OpenResponses Gateway shape: discovery/health unified app; /v1/chat only on optional RA#2091
Conversation
- Implement OpenAICompatProvider with standard endpoints: - POST /v1/chat/completions (with streaming) - POST /v1/completions - GET /v1/models - POST /v1/tools/invoke (PraisonAI extension) - Add 'praisonai serve openai' command for compatibility layer - Create comprehensive test suite with OpenAI Python client - Enable drop-in replacement for OpenAI client libraries Addresses missing OpenAI-compatible HTTP surface vs OpenClaw Gateway. Uses existing PraisonAI capabilities.completions infrastructure with OpenAI request/response format conversion. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-authored-by: praisonai-triage-agent[bot] <praisonai-triage-agent[bot]@users.noreply.github.com>

Code Review
This pull request introduces an OpenAI API compatibility layer to PraisonAI, adding a new serve openai CLI command, an OpenAICompatProvider supporting standard OpenAI endpoints, and a test suite. The review identified several critical issues: importing non-existent functions from server.py that will crash the server on startup, a bug in streaming chat completions that causes an AttributeError, and hardcoded URLs for the agents provider that will cause tool invocation to fail. Additionally, the reviewer recommended avoiding real LLM calls in the health check, adding defensive guards for potentially None input data, and using safer dictionary access to prevent runtime exceptions.

The functions create_server and register_provider do not exist in src/praisonai/praisonai/endpoints/server.py. Attempting to import them will raise an ImportError immediately on startup, crashing the server. Use create_unified_app, register_provider_to_discovery, and register_endpoint_to_discovery instead.

When stream=True, calling openai_provider.invoke first will delegate to chat_completion(..., stream=True), which crashes with an AttributeError because it tries to access .choices on the returned generator. This causes streaming requests to always fail with a 400 error. Additionally, calling invoke and then invoke_stream would perform the LLM call twice. The streaming response should also use the standard text/event-stream media type.

Add an --agents-url option to allow users to specify the URL of their running Agents API server. Hardcoding it to the same host and port as the OpenAI server will cause tool invocation to fail with a 404, as the agents API endpoints are not registered on this server.

The health check should not make a real external LLM API call (chat_completion). This is slow, consumes API tokens, risks hitting rate limits, and will mark the entire service as unhealthy if the external provider is down. Instead, verify that the dependencies can be imported successfully.

--reload flag always raises ValueError at startup
uvicorn.run() requires the app argument to be a string import path (e.g. "module:app") whenever reload=True. Passing a FastAPI instance — as done here — causes uvicorn to raise ValueError: reload requires that 'app' is a string. That exception is caught by the broad except Exception handler and exits with code 1, printing "Failed to start OpenAI server", which makes the failure look like an infrastructure problem rather than a misconfiguration. The --reload flag is exposed in the CLI and documented in the help text, so any user who passes it will see a silent crash.

Inline comments:
In `@src/praisonai/praisonai/cli/commands/serve.py`:
- Around line 632-634: Malformed JSON in the request body can cause unhandled
exceptions that bypass provider error mapping at lines 632-634. Create a helper
function to safely parse and validate the request body JSON, catching
JSONDecodeError and non-object payloads to return OpenAI-style 400 error
responses. Apply this helper function consistently across all three POST
endpoints: the current endpoint at line 632, the /v1/completions endpoint at
lines 666-667, and the /v1/tools/invoke endpoint at lines 685-686, replacing the
direct `await request.json()` calls with the helper to ensure all JSON parsing
errors are normalized into proper error responses before the `body.get()` call.
- Around line 589-617: The OpenAI-compatible server accepts an --api-key
parameter for authentication but does not enforce API key validation on incoming
requests to the /v1/* endpoints. Apply the existing _require_api_key() guard to
the /v1/completions, /v1/models, and /v1/tools/invoke endpoint handlers to
verify that inbound requests include the correct bearer token before processing
them. This should be done in the endpoint registration or middleware setup where
create_unified_app is used to ensure all authentication-required endpoints are
protected.
- Around line 704-710: The uvicorn.run() call passes a dynamically constructed
FastAPI app object with reload=True, but Uvicorn's reload mode requires an
importable module path string, not an in-memory app object. Set the reload
parameter to False in the uvicorn.run() call since the app is created
dynamically and cannot be reloaded from an import path.
In `@src/praisonai/praisonai/endpoints/providers/openai_compat.py`:
- Around line 206-209: The code currently uses .get() with default values for
required fields (messages around line 206, prompt around line 248, and tool_name
around line 328) instead of validating their presence. Replace these silent
defaults with explicit validation that raises an appropriate error (such as a
ValueError or validation exception) when these required fields are missing from
the input_data dictionary. This ensures requests conform to the declared
endpoint schema and prevents malformed requests from being processed further
into the system.
- Around line 21-27: The docstring (lines 21-27) and the capability list (around
line 56) advertise support for embeddings endpoints and capabilities that are
not actually implemented in the list_endpoints() or invoke() methods. Remove the
`/v1/embeddings (if available)` line from the docstring that documents the
implemented endpoints, and remove "embeddings" from the capabilities list
declared around line 56-57 to ensure the advertised contract matches what is
actually implemented.
- Around line 177-181: Replace the direct inclusion of str(e) in the error field
of InvokeResult responses with a generic, client-safe error message. Instead of
returning f"Internal error: {str(e)}", return a stable message like "Internal
error" or "An error occurred while processing your request". Capture the actual
exception details by logging them internally using appropriate logging
mechanisms so diagnostics are available for debugging without exposing sensitive

- Around line 363-364: The streaming path is forcing non-streaming behavior by
passing stream=False to the _handle_chat_completions method on line 364, then
artificially chunking the response character-by-character in the subsequent SSE
emission logic (lines 412-427). Instead, pass stream=True to
_handle_chat_completions to enable actual streaming, then update the SSE
emission logic to properly iterate over token-level chunks from the streaming
response rather than breaking the result into individual characters. This will
reduce first-token latency and minimize excessive SSE event generation.
In `@test_openai_compatibility.py`:
- Around line 135-142: The requests.post call is missing a timeout parameter,
which can cause the test to hang indefinitely if the server becomes unresponsive
and blocks the CI/CD pipeline. Add a timeout parameter to the requests.post call
that sends to "http://localhost:8765/v1/tools/invoke" with an appropriate
timeout value (such as 5 or 10 seconds) to ensure the test fails quickly rather
than blocking indefinitely when the server is unavailable or slow to respond.

Nitpick comments:
In `@test_openai_compatibility.py`:
- Line 192: The zip() function call in the for loop iterating over tests and
results lacks the strict=True parameter, which would provide defensive
programming by catching length mismatches between the lists. Modify the
zip(tests, results) call to include strict=True as a parameter so that a
ValueError is raised if the tests and results lists have different lengths,
helping catch logic errors early.

Enforce --api-key on inbound requests.
--api-key is documented as authentication, but none of the /v1/* handlers verifies the client’s bearer key; it is only passed into OpenAICompatProvider. That leaves chat/completions and /v1/tools/invoke unauthenticated whenever this server is reachable.

🧩 Analysis chain
🌐 Web query:
Does uvicorn.run support reload=True when the ASGI app is passed as a FastAPI object instead of an import string, and what does the current Uvicorn documentation recommend?
💡 Result:
Uvicorn does not support the reload=True option when the ASGI application is passed as an object [1][2]. If you attempt to use reload=True with an application instance, Uvicorn will typically fail or display a warning because it requires an import string (e.g., "main:app") to properly manage the lifecycle of the reloaded processes [3][2]. The current Uvicorn documentation explicitly recommends using the import string style when running programmatically if you require features like auto-reloading or multiple workers [1][4]. When using these features, you must pass the application as a string representing the import path, and it is strongly advised to wrap the uvicorn.run call within an if name == 'main': block to prevent issues with multiprocessing [5][1][4].

- 5: https://uvicorn.dev/settings/?h=reload
Reject --reload for dynamically constructed FastAPI app.
The code passes an in-memory FastAPI object to uvicorn.run() with reload=True, but Uvicorn's reload mode requires an import string (e.g., "main:app") to function. This feature is broken and will fail or be silently ignored. Either disable reload here or extract the app into an importable module.

Enforce required request fields instead of silently defaulting.
