Fix API Key Authentication Issue

My application suddenly stopped authenticating because the service is rejecting the API key I pass in the URL. I’m not sure whether the key itself is malformed, being encoded incorrectly, or if I’m missing a parameter altogether, so I need a fresh set of eyes to pinpoint and resolve the problem. Here’s what I know so far: • The call uses the API key directly in the URL, not in headers or via OAuth. • The response from the endpoint throws an authentication error every time. • I haven’t yet confirmed that the key’s format matches the provider’s latest specs. Your job is to: • Verify that the key is structured exactly as the provider expects (length, checksum, prefix, etc.). • Adjust my request string or parameters so the key authenticates successfully. • Provide a brief explanation of what was wrong so I can avoid the same issue later. If you’ve debugged API key issues before and can hop in quickly, I’d love your help.
