You want to protect your Langchain API so that each user can only make 10 calls per minute and must authenticate with an API key. Which approach correctly combines rate limiting and authentication?

hard📝 Application Q15 of 15

LangChain - Production Deployment

AUse a RateLimiter instance with max_calls=10 and pass api_key='USER_KEY' when creating the client

BOnly use RateLimiter with max_calls=10, no need for api_key

CAuthenticate with api_key but do not use rate limiting

DUse RateLimiter with max_calls=100 and api_key='USER_KEY'

Step-by-Step Solution

Solution:

Step 1: Understand requirement for both rate limiting and authentication
We need to limit calls to 10 per minute and verify user identity with API key.
Step 2: Evaluate options for correct combination
Use a RateLimiter instance with max_calls=10 and pass api_key='USER_KEY' when creating the client correctly sets RateLimiter to 10 calls and passes api_key for authentication.
Final Answer:
Use a RateLimiter instance with max_calls=10 and pass api_key='USER_KEY' when creating the client -> Option A
Quick Check:
Combine rate limiting and api_key for security [OK]

Quick Trick: Combine RateLimiter and api_key for full protection [OK]

Common Mistakes:

MISTAKES

Skipping authentication or rate limiting
Setting wrong max_calls value
Confusing rate limit with authentication token
