# Deck API documentation

> The Deck API gives you programmatic access to computer use agents and agent infrastructure.

Deck computer use agents operate software like a human does. Connect and automate websites and services that lack APIs.

## Why use Deck

* **Works on any software.** If a human can use it, Deck can automate it. Create a source from any website and start running tasks.
* **Credential Vault.** Securely store credentials on behalf of your users and use them safely in your automated tasks.
* **Structured, deterministic output.** Every task returns structured JSON matching a defined schema. Predictable output from AI agents.
* **One agent or thousands.** Deck provisions isolated sessions on demand. Go from one agent to hundreds running in parallel.
* **Built-in observability.** Live session streaming while an agent works. Screenshot and agent reasoning artifacts for completed sessions.
* **Event-driven by default.** Results are pushed to webhooks, SQS, Pub/Sub, or any supported destination.
