Get Batch

Tool to retrieve the details of a batch with the specified name. Use when you need to check the status or configuration of an existing batch.

Get Batch Status

Tool to retrieve the current status of a batch and task completion counts. Use when you need to monitor batch progress or check how many tasks are pending or completed.

Get Fixless Audits

Tool to retrieve fixless audits by task ID or audit ID. Use when you need to fetch audit information for quality assessment. At least one of task_id or id must be provided.

Get Project

Tool to retrieve details about a specific Scale AI project using its unique identifier. Use when you need to get project metadata including type, name, parameter history, and creation timestamp.

Get Quality Labelers

Tool to retrieve training attempts matching provided filter parameters. Use when you need to assess labeler performance and understanding of task instructions. At least one of quality_task_ids or labeler_emails must be provided.

Get Studio Assignments

Tool to retrieve current project assignments of all active team users in Scale AI Studio. Use when you need to view team member assignments and workload distribution. Excludes invited or disabled team members.

Get Studio Batches

Tool to retrieve basic information about all pending batches in Studio. Use when you need to list batches organized by priority level.

Get Teams

Tool to retrieve basic information about all team members associated with the account. Use when you need to list team members, check roles, or view notification preferences.

Get Task by ID

Tool to retrieve detailed information about a specific task using its task ID. Use when you need to check task status, retrieve results, or analyze task metadata.

Get Secure Task Response URL

Tool to retrieve secure authenticated task response data. Use when you need to access stored response data for 2D segmentation, video, and lidar tasks that cannot be included in the task JSON.

Import File

Tool to import files from an external URL endpoint into Scale's system rather than uploading directly from local storage. Use when you need to import files from remote URLs for Scale AI projects or data labeling tasks.

Invite Team Member

Tool to invite users by email to team with specified role. Use when you need to add new team members with roles like labeler, member, or manager.

Frequently asked questions

What can I automate with Scale ai on Definable?

Anything Scale ai exposes through its API. Common artificial intelligence workflows on Definable include route to the best model per task, mix providers in one workflow, fall back on rate-limits. Personas can call any of the 40 Scale ai tools directly, then chain the result into another integration without you writing code.

How does Scale ai authentication work?

Scale ai uses API_KEY on Definable. You connect once from the integrations page, scoped to the permissions you choose, and from then on any persona that has the integration enabled can act on your behalf. Tokens are encrypted at rest and rotated automatically.

Is the Scale ai integration included in my Definable plan?

Yes — every Definable plan, including Starter, includes access to all 40 Scale ai tools. You only need a separate Scale ai subscription if Scale ai itself charges per seat or per API call.

Is using Scale ai through Definable secure?

Every call from a persona to Scale ai is logged with the user, persona, prompt, and response. Tokens never leave Definable's secrets vault, scopes are configurable per persona, and you can revoke access at any time from the integration page.

How do I get started with Scale ai on Definable?

Sign up for Definable, open the integrations page, find Scale ai, and connect via OAuth or API key. You can immediately attach Scale ai to any persona and start running workflows. The free Starter plan includes 5,000 credits/month.

What Scale ai actions does Definable expose?

Definable exposes all 40 Scale ai actions as callable tools — including `Add Studio Assignments`, `Add Task Tags`, `Create Batch`, plus 37 more. Each tool gets a typed parameter schema so personas know exactly how to call it.
