Installation

Using pip

pip install arize-ax-cli

From source

git clone https://github.com/Arize-ai/arize-ax-cli.git
cd ax-cli
pip install -e .

Verify Installation

ax --version

Quick Start

1. Initialize Configuration

The first time you use the CLI, you'll need to create a configuration profile:

ax config init

This interactive setup will:

• Detect existing ARIZE_* environment variables and offer to use them
• Guide you through credential setup if no environment variables are found
• Create a configuration profile (default or named)
• Save your preferences for output format, caching, and more

Example output:

     _         _                 _   __  __
    / \   _ __(_)_______        / \  \ \/ /
   / _ \ | '__| |_  / _ \      / _ \  \  /
  / ___ \| |  | |/ /  __/     / ___ \ /  \
 /_/   \_\_|  |_/___\___|    /_/   \_\_/\_\
                  AI Observability Platform

Welcome to Arize AX CLI!
No configuration found. Let's set it up!

Environment Variable Detection

  ✓ Detected ARIZE_API_KEY = ak_***************xyz

Create config from detected environment variables? [Y/n]: y

Configuration saved to profile 'default'

You're ready to go! Try: ax datasets list

2. Verify Configuration

Check your configuration:

ax config show

3. Start Using the CLI

List your datasets:

ax datasets list

List your projects:

ax projects list

Configuration

The Arize CLI uses a flexible configuration system that supports multiple profiles, environment variables, and two setup modes.

Configuration Commands

Command	Description
ax config init	Create a new configuration profile interactively
ax config list	List all available profiles
ax config show	Display the current profile's configuration
ax config use <profile>	Switch to a different profile
ax config delete <profile>	Delete a configuration profile

Configuration Modes

When you run ax config init, you'll be prompted to choose between two configuration modes:

Simple Configuration (Recommended)

Best for: Most users, cloud deployments, standard Arize usage

The simple setup only asks for the essentials:

• API Key: Your Arize API key
• Region: US, EU, or leave unset (auto-detect)
• Output Format: table, json, csv, or parquet

Example:

Choose configuration mode:
> Simple (recommended)
  Advanced

API Key: Insert value
API Key (e.g., ak-123...): [hidden input]

Region:
> (leave empty for unset)
  US
  EU
  Use environment variable

Default output format:
> table
  json
  csv
  parquet

Generated configuration:

[profile]
name = "default"

[auth]
api_key = "ak_your_api_key_here"

[routing]
region = "US"

[output]
format = "table"

Advanced Configuration

Best for: On-premise deployments, Private Connect, custom routing, performance tuning

The advanced setup provides full control over:

1. API Key: Your Arize credentials
2. Routing: Choose from multiple strategies:
   • No override (use defaults)
   • Region-based routing (US, EU)
   • Single endpoint (on-premise deployments)
   • Base domain (Private Connect)
   • Custom endpoints & ports (granular control)
3. Transport: Performance tuning:
   • Stream max workers
   • Stream max queue bound
   • PyArrow max chunksize
   • Max HTTP payload size
4. Security: TLS certificate verification
5. Output Format: Default display format

Example routing options:

What type of override should we setup?
  0 - No override (use defaults)
  1 - Region (for region-based routing)
  2 - Single endpoint (typical for on-prem deployments)
> 3 - Base Domain (for Private Connect)
  4 - Custom endpoints & ports

Generated configuration (example with Private Connect):

[profile]
name = "production"

[auth]
api_key = "${ARIZE_API_KEY}"

[routing]
base_domain = "arize-private.yourcompany.com"

[transport]
stream_max_workers = 8
stream_max_queue_bound = 5000
pyarrow_max_chunksize = 10000
max_http_payload_size_mb = 8

[security]
request_verify = true

[storage]
directory = "~/.arize"
cache_enabled = true

[output]
format = "json"

Configuration File Location

Configuration files are stored at:

• Linux/macOS: ~/.arize/config/<profile>.toml
• Windows: %USERPROFILE%\.arize\config\<profile>.toml

Configuration Reference

All Available Sections

Authentication (required)

[auth]
api_key = "ak_your_api_key_here"
# Or use environment variable reference:
api_key = "${ARIZE_API_KEY}"

Routing (choose one strategy)

[routing]
# Option 1: Region-based (recommended for cloud)
region = "US"  # or "EU"

# Option 2: Single endpoint (on-premise)
single_host = "arize.yourcompany.com"
single_port = "443"

# Option 3: Base domain (Private Connect)
base_domain = "arize-private.yourcompany.com"

# Option 4: Custom endpoints (advanced)
api_host = "api.arize.com"
api_scheme = "https"
otlp_host = "otlp.arize.com"
otlp_scheme = "https"
flight_host = "flight.arize.com"
flight_port = "443"
flight_scheme = "grpc+tls"

Transport (optional, advanced only)

[transport]
stream_max_workers = 8
stream_max_queue_bound = 5000
pyarrow_max_chunksize = 10000
max_http_payload_size_mb = 8

Security (optional, advanced only)

[security]
request_verify = true  # Set to false to disable SSL verification (not recommended)

Storage (optional)

[storage]
directory = "~/.arize"
cache_enabled = true

Output (optional)

[output]
format = "table"  # Options: table, json, csv, parquet

Using Environment Variables

The CLI can detect and use environment variables in two ways:

1. Auto-Detection During Setup

When you run ax config init, the CLI automatically detects existing ARIZE_* environment variables and offers to use them:

ax config init

Environment Variable Detection

  ✓ Detected ARIZE_API_KEY = ak_***************xyz
  ✓ Detected ARIZE_REGION = US

Create config from detected environment variables? [Y/n]: y

This will create a configuration that references the environment variables:

[auth]
api_key = "${ARIZE_API_KEY}"

[routing]
region = "${ARIZE_REGION}"

2. Manual Environment Variable References

During both Simple and Advanced setup, you can choose "Use environment variable" for any field to reference an environment variable:

API Key:
  Insert value
> Use environment variable

Environment variable name for API Key: ARIZE_API_KEY

Viewing Expanded Values

To see the actual values (with environment variables expanded):

ax config show --expand

Without --expand, you'll see the variable references like ${ARIZE_API_KEY}.

Multiple Profiles

Create different profiles for different environments:

# Create a production profile
ax config init
# Enter profile name: production

# Create a staging profile
ax config init
# Enter profile name: staging

# List all profiles
ax config list

# Switch profiles
ax config use production
ax config use staging

# Use a specific profile for a single command
ax datasets list --profile production

Shell Autocompletion

Enable tab completion for your shell to autocomplete commands, options, and arguments.

Quick Install (Recommended)

The CLI includes a built-in installer that automatically configures completion for your shell:

ax --install-completion

This will:

• Detect your current shell (bash, zsh, or fish)
• Install the appropriate completion script
• Show you instructions to activate it

After running the command, restart your shell or open a new terminal window for the changes to take effect.

Verify Installation

Once installed, test tab completion:

ax <TAB>         # Shows available commands (datasets, projects, config, cache)
ax datasets <TAB> # Shows dataset subcommands (list, get, create, delete)
ax datasets list --<TAB>  # Shows available options

Manual Installation (Alternative)

If you prefer to see or customize the completion script before installing:

# View the completion script for your shell
ax --show-completion

# Save it to a file and source it manually
ax --show-completion >> ~/.bashrc  # For bash
ax --show-completion >> ~/.zshrc   # For zsh

Supported Shells

• Bash (Linux, macOS, Windows Git Bash)
• Zsh (macOS default, Oh My Zsh)
• Fish (Linux, macOS)
• PowerShell (Windows)

Using a Different Profile for a Command

ax datasets list --space-id sp_abc123 --profile production

Pagination

List more datasets using pagination:

# First page
ax datasets list --space-id sp_abc123 --limit 20

# Next page (use cursor from previous response)
ax datasets list --space-id sp_abc123 --limit 20 --cursor <cursor-value>

Working with Multiple Environments

# Setup profiles for different environments
ax config init  # Create "production" profile
ax config init  # Create "staging" profile

# Switch contexts
ax config use production
ax datasets list --space-id sp_prod123

ax config use staging
ax datasets list --space-id sp_stage456

Advanced Topics

Output Formats

The CLI supports multiple output formats:

1. Table (default): Human-readable table format
2. JSON: Machine-readable JSON
3. CSV: Comma-separated values
4. Parquet: Apache Parquet columnar format

Set default format in config:

ax config init  # Select output format during setup

Or override per command:

ax datasets list --output json
ax datasets list --output datasets.csv
ax datasets list --output datasets.parquet

Programmatic Usage

Integrate with scripts:

#!/bin/bash

# Export datasets to JSON
DATASETS=$(ax datasets list --space-id sp_abc123 --output json)

# Process with jq
echo "$DATASETS" | jq '.data[] | select(.name | contains("test"))'

# Export to file
ax datasets list_examples ds_xyz789 --output data.parquet

Environment Variables

The CLI respects these environment variables:

• ARIZE_API_KEY: Your Arize API key
• ARIZE_REGION: Region (US, EU, etc.)
• Any other ARIZE_* variables will be detected during ax config init

Debugging

Enable verbose mode to see detailed SDK logs:

ax datasets list --space-id sp_abc123 --verbose
