# `api/not-found` — Requested resource was not found

## When it occurs
The NSIP API returned HTTP 404 — the requested animal, flock, or other resource
does not exist at the given identifier.
## Recovery
Verify the identifier exists (e.g. via `nsip search`). The suggested fix is
`maybe_incorrect`: the right identifier is not known to the tool, so an agent
should surface this to a human or search rather than guess.
## Example
```json
{
"type": "https://github.com/zircote/nsip/blob/main/docs/reference/errors/api/not-found.md",
"title": "Requested resource was not found",
"status": 404,

"instance": "urn:nsip:details:1d2e3f4a-5b6c-7d8e-9f0a-1b2c3d4e5f6a",
"exit_code": 1,
"suggested_fix": "verify the identifier exists in the NSIP database (try `nsip search`)",
