  "summary": "When you point Claude Code or Codex at a third-party relay and it errors, read the status code first — it tells you exactly what's wrong: 404 — wrong address. Usually the /v1 on base_url : Anthropic-compatible endpoints have no /v1 (Claude Code appends /v1/messages ); OpenAI-compatible endpoints need /v1 . 401 / 403 — auth failed. Key copied in full? Credit left? Model id in the station's list?…",
