# Validate Signals (Pre-flight)

> Validate signal payloads without persisting them.

The validation endpoint allows you to test your ingestion payloads during development without polluting the SignalArk database.

It accepts the exact same schema as `POST /v1/signals/ingest`.

### Behavior

* Runs full Zod schema validation.
* Checks enum values (like `signal_source`).
* Simulates account matching to see if `company_domain` formatting is acceptable.
* **Does not** persist signals.
* **Does not** trigger the AI classification pipeline.
* **Does not** consume rate limits or credits.

### Response

Returns a detailed breakdown of which items in your batch passed validation and the specific error messages for those that failed.
