…examples Add an OrcaRouter-aware LLM factory that routes the LangGraph examples through OrcaRouter's OpenAI-compatible gateway (https://api.orcarouter.ai/v1) when ORCAROUTER_API_KEY is set, falling back to the existing OpenRouter/OpenAI resolution otherwise. Mirrors the existing OpenRouter wiring across basic_integration, cross_session_recall, custom_memory_saver, research_pipeline, and memanto_base_store, and documents the ORCAROUTER_API_KEY option in .env.example and the READMEs. Signed-off-by: XiaoHuo888-hue <jinhao.song@myflashcloud.com>
📝 WalkthroughWalkthroughThe LangGraph Memanto examples now support OrcaRouter through shared configuration and LLM factories. Existing OpenRouter and OpenAI fallback behavior remains supported. Startup validation and setup documentation now include OrcaRouter credentials and overrides. ChangesOrcaRouter integration
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to The provider-selection changes can reject valid OpenAI-only setups and may ignore an explicitly configured OrcaRouter model in some examples, causing runs to fail or use an unintended model. These bounded integration issues should be fixed before merging. Sequence Diagram(s)sequenceDiagram

Define one OrcaRouter model-override contract.
The OrcaRouter paths use incompatible override rules. Users cannot reliably select a gateway model.

Do not present LANGGRAPH_LLM as a credential alternative.
The graph requires a provider key. LANGGRAPH_LLM only selects the model after credentials exist. Rename the entry to describe a missing provider key, list all three supported keys, and describe LANGGRAPH_LLM as an optional model override.

Allow the existing OpenAI fallback in this entry point.
Line 30 rejects a configuration with only OPENAI_API_KEY, so run_research() never runs for an OpenAI-only setup. The shared factory still supports OpenAI fallback. Load OPENAI_API_KEY and include it in this condition and the error message.

Summary
Adds OrcaRouter as a named OpenAI-compatible
provider for the LangGraph examples in
examples/langgraph-memanto/. OrcaRouteris a smart model-routing gateway that exposes models from OpenAI, Anthropic,
Google, DeepSeek, Qwen, MiniMax and others behind a single endpoint and API key.
It also runs gateway-level, zero-trust security for AI agents on the same
endpoint — screening every prompt/response and governing every tool call on a
default-deny basis, with no application code changes.
Disclosure: I'm an engineer on the OrcaRouter team.
What this changes
The LangGraph examples previously hard-coded OpenRouter as their OpenAI-compatible
LLM route (
ChatOpenAI(base_url="https://openrouter.ai/api/v1")). This PR makesevery example prefer a named OrcaRouter provider whenever
ORCAROUTER_API_KEYis set, while keeping the existing OpenRouter/OpenAI behaviour as the fallback so
nothing breaks for current users.
examples/langgraph-memanto/orcarouter_llm.py(new): sharedbuild_orcarouter_llm()factory. When
ORCAROUTER_API_KEYis set it returns aChatOpenAIpointed athttps://api.orcarouter.ai/v1with the smart-routing modelorcarouter/auto;otherwise it falls back to the exact OpenRouter/OpenAI resolution used before.

ORCAROUTER_API_KEY, optionalORCAROUTER_MODEL/ORCAROUTER_API_BASE).Why a separate provider rather than the OpenAI-compatible escape hatch
This mirrors how the examples already wire OpenRouter as a named provider, so the
model picker, env vars and docs stay consistent for users. Setting
ORCAROUTER_API_KEYis a one-line switch to OrcaRouter's smart routing and itsgateway-level security controls, with no code changes in the agent graph itself.
