# not_found: Not found

Status 404.

## 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.

## Example

```json
{
  "type": "https://unique.domains/api/problems/not_found",
  "title": "Not found",
  "status": 404,
  "detail": "No ending \"unknownending\" in the TLD catalog.",
  "instance": "/v1/tlds/unknownending",
  "code": "not_found"
}
```
