# tRPC -- Validators

Check what goes into and comes out of every tRPC call

## What this does

Your tRPC procedures receive data from outside, and you want bad data stopped at the door. This helps you declare what each call accepts and returns, using a library such as Zod or your own function. Several input checks can be combined, and if what a procedure returns fails its check, the call ends in a server error.

### Top 3 things it does for you

- Reject bad input before my code runs
- Check what my procedures send back
- Use the validation library I already know

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 tRPC -- Validators

This configures input and output validation with .input() and .output(), using Zod, Yup, Superstruct, ArkType, Valibot, Effect or custom validator functions. Standard Schema protocol is supported.

Multiple .input() calls can be chained to merge object schemas. When output validation fails, the call returns INTERNAL_SERVER_ERROR.

## Questions

### Is tRPC -- Validators safe to install?

AIR scanned this exact version of tRPC -- Validators and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit 23c723cfeaf0, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/validators.
