operation_retired

What happened

You called an endpoint that FullVision has retired. The path is real: it was served and then withdrawn, which is why this is a 410 and not a 404.

Why it usually happens

An endpoint that was renamed, or moved out of the public API, keeps answering with Deprecation and Sunset headers until its sunset date. After that date it answers with this error for a while, then disappears.

How to fix

• When the message names a replacement, call that instead.
• Otherwise the endpoint is no longer offered to API keys. The stability page explains what changed and when.
• Watch for the Deprecation and Sunset response headers to catch the next change before it lands.
