…error As of 2026-04-04, Anthropic's third-party-tool enforcement returns HTTP 400 with the error body "You're out of extra usage. Add more at claude.ai/settings/usage and keep going." when a subscription-OAuth call is classified as third-party. This string was not matched by _BILLING_PATTERNS, so classify_api_error returned format_error (retryable=False, should_rotate_credential=False) instead of billing (retryable=False, should_rotate_credential=True, should_fallback=True). The downstream effect: cron sessions hitting the cap could still fall back (format_error also sets should_fallback), but without credential rotation semantics or a clean 'billing' signal for metrics/telemetry. Adding 'out of extra usage' to _BILLING_PATTERNS makes the existing billing-error recovery path engage on the new failure mode. Adds one regression test against a MockAPIError(status=400, body=...). 104 tests passing (up from 103).
