Status 404

not_found

Not found

Why it happens

The path names something the catalog does not hold: an ending, an event, a trend, a registrar, or a name an endpoint needs stored. detail says which, and often what to call instead.

What to do

Check the value against the list endpoint it comes from. For a domain name, GET /names/{name} answers 200 with tracked: false when the catalog never stored it, and the live check stores it.
