# Perimeter X Hold Captcha (pxhc)

A PerimeterX press-and-hold captcha bypass without a browser. When a PerimeterX site blocks you with the "press & hold to confirm you are human" challenge, Takion solves it and returns the \_px3 cookie

{% hint style="danger" %}
**Trial and plan access is gated.** A PerimeterX bypass can be abused for fraud, so trial access is not automatic, and PXHC additionally requires your key to be whitelisted for the service. Please contact us on [Discord](https://takionapi.tech/discord) or [via mail](mailto:sales@takionapi.tech) , we'll need to verify your business first.

Check our example bundles in order to validate your implementation against our validate ones, with correct headers order, TLS and flow from our [**Github repo**](https://takionapi.tech/examples)
