An agent is an automation scoped to a use case that organizes related tasks. ## OpenAPI ````yaml /api-reference/v2.json post /agents openapi: 3.1.1 info: title: Deck API version: 2.0.0 servers: - url: https://api.deck.co/v2 description: Production security: - BearerAuth: [] tags: - name: Agents description: >- Agents are the AI workers that execute tasks against sources. Create and manage the agents in your organization. - name: Components description: >- Embeddable UI components. Create short-lived session tokens for the Auth Component. - name: Platform description: Organization-wide platform settings, such as the static IP range. - name: Credentials description: >- Credentials store the login details an agent uses at a source. Values are tokenized at rest and never returned in plaintext. - name: Event Destinations description: >- Where Deck delivers events: webhooks, SQS, Kinesis, S3, and more. Manage destinations and inspect delivery attempts. - name: Events description: >- Immutable records of things that happened in your organization, such as a task run completing or a credential being verified. - name: Sessions description: >- Sessions are agent sandbox lifetimes. A session is created for each task run (or explicitly) and counts toward your concurrency limit. - name: Sources description: >- Sources are the websites and portals agents work against. Register, inspect, reset, and delete them. - name: Storage description: >- Files produced by task runs: downloaded documents, exports, and extraction results. - name: Task Runs description: >- A task run is one execution of a task. Inspect status and output, retrieve files and screenshots, cancel runs, and answer interaction requests. - name: Tasks description: >- Tasks define reusable units of work for an agent: a goal, an input schema, and an output schema.
