Error "Call usage limit has been reached." returned with GetItem API

[s.m6494]

I am currently using the GetItem API in our live web system, but starting today, I've been receiving the following response:

<?xml version="1.0" encoding="UTF-8"?>
<GetItemResponse   xmlns="urnapis:eBLBaseComponents">
    <Timestamp>2024-04-07T01:34:57.826Z</Timestamp>
    <Ack>Failure</Ack>
    <Errors>
        <ShortMessage>Call usage limit has been reached.</ShortMessage>
        <LongMessage>Your application has exceeded the usage limit on this call. Please make a call to the Developer Analytics API to check your call usage.</LongMessage>
        <ErrorCode>518</ErrorCode>

    </Errors>
    <Version>1175</Version>
    <Build>E1175_CORE_API5_19110890_R1</Build>
</GetItemResponse>

I have checked the usage status by calling the Analytics API, but it hasn't reached the usage limit.

The same error is occurring with the GetUserPreferences API and the ReviseInventoryStatus API as well.

What should I do to resolve this?

Hi @s.m6494 

If you need higher call limits, you can complete our Application Growth Check, to verify that your application is adhering to eBay's API License Agreement, and that you've made the most efficient use of the APIs you've implemented.

We have reviewed our application's processing and were able to reduce the number of API calls.

As a result, we no longer exceed the API call limit.

This matter has been resolved.

Thank you for your reply.
