# API Not Found

Find out whether the export you want actually exists

## What this does

You wrote code against a table library and something you expected isn't there - a method comes back undefined, a key is missing, or the compiler complains. This helps you check what actually exists before you guess at an API that was never real. Reach for it when an example you copied doesn't line up with the version you're on.

### Top 3 things it does for you

- Track down a missing option or method
- Check whether an example is out of date
- Work out why a type error keeps appearing

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## About API Not Found

When code hits a type error, an undefined feature method, a missing object key, or an adapter that doesn't line up, the tempting next move is to guess at the API. This is meant to be read before that guess.

It covers what TanStack Table v9 does and does not expose: exports, options, state slices, and instance methods. That includes the case where the example you're following was written for the older shape of the library.

## Questions

### Is API Not Found safe to install?

AIR scanned this exact version of API Not Found and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit d9cca007c015, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/api-not-found.

### How do I install API Not Found?
