Connector docs — Anthropic

Exactly what CostMon asks for to read Anthropic

CostMon calls two read-only Anthropic Admin API endpoints: the organization cost report, then the messages usage report to add a token breakdown.

See the security model →See the solution page →

What CostMon calls

The literal API surface, nothing more

GET /v1/organizations/cost_report: Daily cost, grouped by workspace and model.
GET /v1/organizations/usage_report/messages: Per-model input/output token counts for the same window, merged onto the cost rows.

What you supply

Credential and config fields

admin_api_keyAdmin API keysecretrequired

Accepted by the fetcher, not yet in the setup form

days_back: The fetcher's config struct accepts a days_back override, but it isn't exposed as a declared setup-form field.

Minimum permission

Copy this, not a broader role

Credential scope

An Admin API key (sk-ant-admin...), not a regular workspace API key.
Regular API keys cannot read the organization cost or usage reports.
This is an organization-level, not a workspace-level, credential.

Scope of access

What Anthropic access can't reach

Prompts, completions, or any message content
Workspace settings, members, or API keys other than the one you provide

FAQ

Common questions about the Anthropic connector

Can CostMon read my prompts or completions?

No. Both endpoints CostMon calls return cost and token counts only. Message content isn't part of either response.

Will a regular Anthropic API key work?

No. Both endpoints require an Admin API key. A regular workspace key returns a permission error.
