CCAO-F Using the Claude API Practice Question
Exhibit
HTTP/1.1 200 OK anthropic-ratelimit-requests-limit: 1000 anthropic-ratelimit-requests-remaining: 5 anthropic-ratelimit-requests-reset: 2024-05-20T12:00:00Z anthropic-ratelimit-tokens-limit: 400000 anthropic-ratelimit-tokens-remaining: 350000
Refer to the exhibit. Based on the headers returned in the API response, what is the most immediate constraint the developer should be concerned about for their next few requests?
⚠ Common exam trap
Candidates frequently confuse token limits with request rate limits, focusing on the high remaining token count while ignoring the dangerously low number of remaining requests indicated in the headers.

Correct answer & explanation
✓
The request count limit is nearly reached.
The Anthropic API returns rate limit information in the response headers. In this exhibit, the 'anthropic-ratelimit-requests-remaining' value is 5, while the 'tokens-remaining' is 350,000. This indicates that the client is very close to exhausting their allowed number of requests, even though they have plenty of token capacity left. The developer needs to slow down their request frequency.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The application is about to run out of token capacity.
Why it's wrong here
The headers show 350,000 tokens remaining out of a 400,000 limit. This means the application has used only a small fraction of its token quota. Token usage is not the primary concern here. The developer should focus on the request count instead, as that is the resource that is nearly depleted in the current window.
- ✗
The API key has expired and needs to be refreshed by the reset time.
Why it's wrong here
The 'reset' header refers to when the rate limit window restarts, not when the API key expires. API keys do not have a standard expiration tied to rate limit headers. Mistaking rate limit resets for authentication expiry would lead to unnecessary credential management tasks instead of the required traffic throttling to avoid upcoming 429 errors.
- ✓
The request count limit is nearly reached.
Why this is correct
The 'requests-remaining' header shows only 5 units left. This is a very low number compared to the total limit of 1,000. If the developer continues sending requests at the same rate, they will soon receive 429 Too Many Requests errors. They should monitor this header to implement proactive throttling within their application logic.
- ✗
The server is overloaded and will reset at the specified time.
Why it's wrong here
The reset time indicates when the rate limit counters will be cleared, not a server recovery time. A 200 OK response means the server is currently healthy and processing requests. The headers are a preventive warning about client-side usage limits rather than an indication of server-side instability or hardware-level overloading issues.
