LangGraph integration
LangGraph cheap API setup
LangGraph workflows can grow expensive when requests loop or context gets large. Cheaper usage is mostly about stopping waste before it starts. NexRelay keeps the first test small and reversible.

Why this setup works
A dedicated LangGraph key keeps testing separate from production while NexRelay adds prepaid balance checks and request logs.
Recommended setup
Use a lower-cost model first, cap output length, and keep a tight budget on the key.
- One key per LangGraph workflow
- Start with a small budget
- Keep the model list narrow
- Review the first log entry
What to verify
Confirm the request cost stays small and the log reflects the model you actually intended to use.
FAQ
Is cheap API usage only about model price?
No. Output caps, budgets, and request logs often matter more.
Should I start with one cheap key?
Yes. A separate low-risk key makes setup and testing much easier.
