Error Details: Invalid API Key

According to Etherscan, the API is fine, and so is my API key. So, I'm not sure what's going on. Ideas?

Can you run curl 'https://api.etherscan.io/api?module=account&action=balance&address=0x0000000000000000000000000000000000000000&tag=latest&apikey=<YOUR-API-KEY> in your terminal (using your API key) to triple-check that the API key is indeed working fine?

Yeah, it was some weird Etherscan fluke... problem went away on its own after several hours of me wondering what was up. API key was valid/working fine. :-)
