# Create a space
> Create a new space within an organization.
**Payload Requirements**
- `name` and `organization_id` are required.
- The space name must be unique within the organization.
- `description` is optional and defaults to an empty string if omitted.
- System-managed fields (`id`, `created_at`) are generated
automatically and rejected if provided.
This endpoint is in beta, read more [here](https://arize.com/docs/ax/rest-reference#api-version-stages).

- name: AI Integrations
description: |
AI integrations configure access to external LLM providers (e.g. OpenAI,
Azure OpenAI, AWS Bedrock, Vertex AI). Integrations can be scoped to the
entire account, a specific organization, or a specific space.
- name: Annotation Configs
description: >
Annotation configs allow you to define consistent annotation schemas that
can be reused across your workspace, ensuring evaluations are structured
and
comparable over time.
- name: Annotation Queues
description: >
Annotation queues help you organize and manage human evaluation workflows.
Use queues to assign spans or examples to annotators for review and
labeling.
- name: API Keys
description: >
API keys are used to authenticate requests to the Arize API. List your
keys
to view metadata; the raw secret is never returned after creation.
- name: Datasets
description: |
Datasets are structured, version-controlled example collections you use to
run, evaluate, and track LLM experiments.
- name: Evaluators
description: >
Evaluators are reusable evaluation configurations used to assess the
quality
of LLM outputs. They can be template-based (using LLM judges) or
code-based.
- name: Experiments
description: >
Experiments let you systematically test prompt/model changes using
datasets,
tasks, and evaluators.
- name: Integrations
description: >
Integrations configure access to external LLM providers (e.g. OpenAI,
Azure OpenAI, AWS Bedrock, Vertex AI), notifications services (e.g.
PagerDuty, Slack), and
your own agents. Integrations can be scoped to the entire account, a
specific
organization, or a specific space.
- name: Organizations
description: >
Organizations are top-level containers within an Arize AX account for
grouping spaces.
- name: Projects
description: |
Projects represent LLM applications being monitored in Arize where you can
observe traces and spans.
- name: Prompts
description: >
Prompts are reusable, versioned templates for LLM interactions. Use
prompts
to standardize and manage how you interact with LLMs across your
application.
- name: Resource Restrictions
description: |
Endpoints for restricting and unrestricting resources (projects, models).
- name: Role Bindings
description: |
Role bindings assign a role to a user on a resource. REST currently
supports space- and project-scoped bindings.
- name: Roles
description: >
Roles define sets of permissions that can be assigned to users within an
account. Create custom roles to tailor access control to your team's
needs.
- name: Spaces
description: >
Spaces are containers within an organization for grouping related
projects,
datasets, and experiments, enabling collaboration or isolated
experimentation
with role-based access control.
- name: Spans
description: |
Spans represent individual operations within a trace. A span captures the
timing, status, and attributes of a single operation in your application.
- name: Tasks
description: |
Tasks are configurable units of work that tie one or more evaluators to a
data source (project or dataset). Use tasks to automate evaluation of LLM
outputs, with support for continuous evaluation and backfill runs.
- name: Users
description: >
Users represent members of an account. The Users endpoints allow creating,
listing, updating (display name), and removing users from the account
programmatically.
