The org telemetry your connector reads. No enterprise onboarding.

The Admin API surface engineering-intelligence tools document — members, workspaces, API-key metadata, usage & cost reports, and Claude Code analytics — for a simulated org whose numbers reconcile with its git history, exactly.

Coverage, hosts and pinned snapshots for Anthropic — 13 of 13 read surfaces served and verified.

01Point your calls at anthropic.

02Send the version header

03Pin a snapshot for CI

01 / Base URL

The Admin API, mirrored.

Point requests at https://anthropic.sandboxapis.dev. Paths, envelopes, and both pagination families mirror api.anthropic.com — including the REQUIRED anthropic-version header (requests without it get the real API's 400, so your client's error handling exercises honestly).

request.sh

curl "https://anthropic.sandboxapis.dev/v1/organizations/usage_report/claude_code?starting_at=2026-05-01&limit=5" \
  -H 'x-api-key: any-key-works' \
  -H 'anthropic-version: 2023-06-01'

02 / Drop in the official SDK

@anthropic-ai/sdk works unmodified.

The only change is baseURL — pointed here at the pinned *.snap. host, so the values below are the values you get. The SDK injects auth and the version header itself, and its typed error classes fire on the sandbox's provider-shaped envelopes (a write raises PermissionDeniedError, as read-only should).

typescript

import Anthropic from "@anthropic-ai/sdk";

const client = new Anthropic({
  apiKey: "any-key-works",
  baseURL: "https://anthropic-2023-06.snap.sandboxapis.dev",
});

// The walk the connector docs name: analytics + the org roster.
const report = await client.get("/v1/organizations/usage_report/claude_code", {
  query: { starting_at: "2026-05-01", limit: 1000 },
});
const users = await client.get("/v1/organizations/users", { query: { limit: 100 } });

04 / Pin a snapshot

Deterministic CI.

The *.snap. baseURL is the whole of it — byte-identical on every request, with model IDs and pricing frozen at the pin's snapshot date. Your FinOps reconciliation logic gets a fixture that never moves.
