Occasionally research requests have been taking a bit longer than one would think they should. It’s part of using the API feed from eBay. The CL data is lightning fast, but the query time, at times, for the other data is in the 5-15 seconds. That’s the difference between spending $1k (like we did) for the API or $10k’s for the data dump.
It’s free, and there is a caching layer in the service. So higher demand calls are definitely returned faster.
While it doesn’t solve the problem, I hope this helps clear up why it happens.
