Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use the Tool's built-in RateLimiter wrapper with a specified max_requests_per_second
LangChain provides a built-in RateLimiter tool wrapper that can be applied to any tool to enforce rate limits. Alternatively, custom retry logic can be added, but using the built-in wrapper is the recommended pattern.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Increase the tool's timeout to reduce request frequency
Why it's wrong here
Timeout controls how long to wait for a response, not the request rate.
- ✗
Deploy multiple agent instances to distribute requests
Why it's wrong here
Multiple instances would increase total request rate, worsening the problem.
- ✗
Ignore rate limits and rely on the LLM to slow down
Why it's wrong here
LLMs do not inherently respect API rate limits; explicit handling is needed.
- ✓
Use the Tool's built-in RateLimiter wrapper with a specified max_requests_per_second
Why this is correct
The RateLimiter wrapper automatically throttles calls to the tool.
