Arize Link

Generate deep links to the Arize UI for projects, traces, spans, sessions, datasets, labeling queues, evaluators, and annotation configs.

When to Use

• User wants a link to a project, trace, span, session, dataset, labeling queue, evaluator, or annotation config
• You have IDs from exported data or logs and need to link back to the UI
• User asks to "open" or "view" any of the above in Arize

Required Inputs

Collect from the user, context (exported trace data or parsed URLs), or the ax CLI:

Always required	Resource-specific
org_id (base64)	project_id + trace_id [+ span_id] — trace/span
space_id (base64)	project_id + session_id — session
	dataset_id — dataset
	queue_id — specific queue (omit for list)
	evaluator_id [+ version] — evaluator

Discover organization and project IDs

Prefer the CLI over asking the user for IDs that it can provide:

ax organizations list --output json

Use .organizations[].id for the organization ID. If more than one organization is returned, match the user-provided organization name or ask them to choose.

To discover a project ID, list projects in the relevant space:

ax projects list --space "{space_name_or_id}" --limit 100 --output json

Use the matching project's id; its space_id supplies the space ID required in the URL. The command accepts a space name or ID; if no space is known, run ax projects list --limit 100 --output json and select the matching project.

All path IDs must be base64-encoded (characters: A-Za-z0-9+/=). A raw numeric ID produces a valid-looking URL that 404s. If the user provides a number, ask them to copy the ID directly from their Arize browser URL (https://app.arize.com/organizations/{org_id}/spaces/{space_id}/…). If you have a raw internal ID (e.g. Organization:1:abC1), base64-encode it before inserting into the URL.

URL Templates

Base URL: https://app.arize.com (override for on-prem)

Project:

{base_url}/organizations/{org_id}/spaces/{space_id}/projects/{project_id}

Trace (add &selectedSpanId={span_id} to highlight a specific span):

{base_url}/organizations/{org_id}/spaces/{space_id}/projects/{project_id}?selectedTraceId={trace_id}&queryFilterA=&selectedTab=llmTracing&timeZoneA=America%2FLos_Angeles&startA={start_ms}&endA={end_ms}&envA=tracing&modelType=generative_llm

Session:

{base_url}/organizations/{org_id}/spaces/{space_id}/projects/{project_id}?selectedSessionId={session_id}&queryFilterA=&selectedTab=llmTracing&timeZoneA=America%2FLos_Angeles&startA={start_ms}&endA={end_ms}&envA=tracing&modelType=generative_llm

Dataset (selectedTab: examples or experiments):

{base_url}/organizations/{org_id}/spaces/{space_id}/datasets/{dataset_id}?selectedTab=examples

Queue list / specific queue:

{base_url}/organizations/{org_id}/spaces/{space_id}/queues
{base_url}/organizations/{org_id}/spaces/{space_id}/queues/{queue_id}

Evaluator (omit ?version=… for latest):

{base_url}/organizations/{org_id}/spaces/{space_id}/evaluators/{evaluator_id}
{base_url}/organizations/{org_id}/spaces/{space_id}/evaluators/{evaluator_id}?version={version_url_encoded}

The version value must be URL-encoded (e.g., trailing = → %3D).

Annotation configs:

{base_url}/organizations/{org_id}/spaces/{space_id}/annotation-configs

Time Range

CRITICAL: startA and endA (epoch milliseconds) are required for trace/span/session links — omitting them defaults to the last 7 days and will show "no recent data" if the trace falls outside that window.

Priority order:

1. User-provided URL — extract and reuse startA/endA directly.
2. Span start_time — pad ±1 day (or ±1 hour for a tighter window).
3. Fallback — last 90 days (now - 90d to now).

Prefer tight windows; 90-day windows load slowly.

Instructions

1. Gather IDs from user, exported data, URL context, or the CLI. Use ax organizations list --output json to obtain org_id; use ax projects list to obtain project_id when needed.
2. Verify all path IDs are base64-encoded.
3. Determine startA/endA using the priority order above for trace, span, and session links.
4. Substitute into the appropriate template and present as a clickable markdown link.

Troubleshooting

Problem	Solution
"No data" / empty view	Trace outside time window — widen startA/endA (±1h → ±1d → 90d).
404	ID wrong or not base64. Re-check org_id with ax organizations list --output json, project_id with ax projects list, and space_id from the browser URL.
Span not highlighted	span_id may belong to a different trace. Verify against exported span data.
org_id unknown	Run ax organizations list --output json and use .organizations[].id. If the CLI cannot access the organization, ask the user to copy it from their Arize browser URL.
