Connecting to Anthropic

Connect your Anthropic account to CloudZero to bring your Anthropic cost and usage data into a unified view of all your cloud and AI spend. CloudZero organizes your Anthropic costs, along with your other costs, into categories (called Dimensions) that matter most to your business. For example: business unit, team, product, feature, environment, customer, or virtually anything else. Once connected and organized, you can quickly answer questions about your spend that matter to your stakeholders.

CloudZero supports two Anthropic connections:

• Anthropic (Platform): Costs by project, model, and operation. Works with any plan that has API Console access (Team, Enterprise, or pay-as-you-go).
• Anthropic Enterprise: Costs by individual user, product, model, and context window. Requires an Enterprise plan with analytics provisioned by Anthropic.

Enterprise customers can configure both. Each connection is a distinct data source with no overlap: Anthropic (Platform) covers API usage (projects, models, operations), while Anthropic Enterprise covers product usage (such as Chat, Claude Code, and Cowork). To isolate one connection in Explorer, filter by the Dimension, Cloud Provider.

Anthropic (Platform)

The Platform connection ingests cost and usage data broken down by project, model, operation, and more. It connects through Anthropic's Usage and Cost API using an Admin API Key from the Claude Console at platform.claude.com. This connection is available to organizations with API Console access, including pay-as-you-go and enterprise API contracts.

What you need

• A CloudZero user with admin permissions
• An Anthropic Admin API Key. Only organization members with the Admin role can create Admin API Keys.
• Your Anthropic Billing Account ID

Step 1: Create an Admin API Key

1. Sign in to the Claude Console at platform.claude.com.
2. Navigate to API Keys in the sidebar. Expand the section to find Admin Keys.
3. Select Create Admin Key and give it a descriptive name (for example, "CloudZero Integration").
4. Copy the key and store it securely. Anthropic does not display the key again after creation.

Step 2: Configure the connection in CloudZero

1. In CloudZero, go to Settings > Cloud Connections.
2. Select Create Connection +.
3. Select the Anthropic tile.
4. Enter a Connection Name. This label identifies the connection throughout CloudZero.
5. Enter your Billing Account ID. You can find this in the Claude Console under Settings.
6. Enter the Admin API Key you created in Step 1.
7. Select Create Connection. You are redirected to Cloud Connections, where your new connection is listed.

What to expect

The connection status changes from Pending Data to Healthy once the first ingest completes. Your Anthropic costs appear across the platform within 24 hours.

Anthropic Enterprise

The Enterprise connection ingests per-user cost and usage data, broken down by user, product, model, and context window. It connects through an Analytics API Key from claude.ai/analytics/api-keys. This connection requires an Anthropic Enterprise plan with analytics provisioned by Anthropic.

What you need

• A CloudZero user with admin permissions
• An Anthropic Enterprise plan with analytics provisioned by Anthropic
• The Primary Owner role on your Anthropic Enterprise organization
• An Analytics API Key with the read:analytics scope, generated from claude.ai/analytics/api-keys. This is a different credential from the Admin API Key used by the Anthropic (Platform) connection.

Step 1: Create an Analytics API Key

1. As the Primary Owner of your Anthropic Enterprise organization, sign in to claude.ai/analytics/api-keys.
2. Create a new Analytics API Key.
3. Provide a descriptive name (for example, "CloudZero Integration").
4. Copy the key and store it securely. Anthropic does not display it again.

Step 2: Create the connection in CloudZero

1. In CloudZero, go to Settings > Cloud Connections.
2. Select Create Connection +.
3. Select the Anthropic Enterprise tile.
4. Enter a Connection Name. This label identifies the connection throughout CloudZero.
5. Enter the Analytics API Key you created in Step 1.
6. Select Create Connection. You are redirected to Cloud Connections, where your new connection is listed.

What to expect

The connection status changes from Pending Data to Healthy once the first ingest completes. Your Anthropic Enterprise costs appear across the platform within 24 hours. CloudZero pulls up to 12 months of historical data on first connection. Data is not available prior to January 1, 2026.

Anthropic reconciles Enterprise billing data for up to 30 days, so recent month costs can shift slightly as Anthropic finalizes the numbers.
