358358The gateway carries model requests, but Claude Code also sends nonessential background traffic outside the gateway path, to Anthropic and to third-party services such as GitHub: version checks, telemetry, release notes, and similar requests. On a network that only allows egress to the gateway, these requests fail and can appear as blocked connections in your egress monitoring.

360Claude Code attaches a credential to a telemetry or usage-metrics request only when the request goes to the host the credential belongs to. While `ANTHROPIC_BASE_URL` points at the gateway, Claude Code sends its telemetry events to Anthropic without your gateway credential. With a [credential variable](#set-the-credential-variable) or `apiKeyHelper` also active, Claude Code doesn't report usage metrics to the Console [analytics dashboard](https://code.claude.com/docs/en/analytics.md#access-analytics-for-api-customers). Before v2.1.246, Claude Code could attach the gateway credential to telemetry and usage-metrics requests bound for Anthropic hosts; model requests always went to the gateway with the credential the gateway expects.
