Anthropic / Claude

Endpoint

Usage Dashboard queries GET /api.anthropic.com/v1/organizations/usage_report/messages for the last 24 hours.

Credential

This requires an Anthropic Admin API key, created under Console → Settings → Organization → Admin API Keys — not a normal inference key.

Metrics

• input_tokens
• output_tokens
• cache_creation_tokens
• cache_read_tokens
• num_requests

Notes

• The adapter requests a 1-hour bucket width and totals every record in the report.
• A 403 usually means the key lacks admin access to the organization.
