By simply altering the base URL and API key, users can experiment with different models like Google's Gemini 2.5 Flash, comparing output quality, latency, cost, and error rates before routing production traffic.", "body_md": "Many AI applications begin with one provider and then need more flexibility: fallback models, model experiments, or different models for different product workflows.\n\n[RouterBase](https://routerbase.com) gives developers an OpenAI-compatible API shape at `https://routerbase.com/v1`\n\n, so the first experiment can stay small: change the base URL, set a RouterBase API key, and choose a model id.\n\n```\ncurl https://routerbase.com/v1/chat/completions \\\n  -H \"Authorization: Bearer $ROUTERBASE_API_KEY\" \\\n  -H \"Content-Type: application/json\" \\\n  -d '{\n    \"model\": \"google/gemini-2.5-flash\",\n    \"messages\": [\n      { \"role\": \"user\", \"content\": \"Explain RouterBase in one sentence.\" }\n    ]\n  }'\njs\nconst response = await fetch(\"https://routerbase.com/v1/chat/completions\", {\n  method: \"POST\",\n  headers: {\n    Authorization: `Bearer ${process.env.ROUTERBASE_API_KEY}`,\n    \"Content-Type\": \"application/json\"\n  },\n  body: JSON.stringify({\n    model: process.env.ROUTERBASE_MODEL || \"google/gemini-2.5-flash\",\n    messages: [\n      { role: \"user\", content: \"Draft a short product update.\" }\n    ]\n  })\n});\n\nif (!response.ok) {\n  throw new Error(`RouterBase request failed: ${response.status}`);\n}\n\nconsole.log(await response.json());\n```\n\nStart with a low-risk workflow, keep the model id configurable, and compare output quality, latency, cost, and error rate before routing more traffic through the new setup.\n\nGood first workflows:", "url": "https://wpnews.pro/news/use-routerbase-as-an-openai-compatible-api-gateway", "canonical_source": "https://dev.to/routerbasecom/use-routerbase-as-an-openai-compatible-api-gateway-2dk7", "published_at": "2026-06-30 17:10:01+00:00", "updated_at": "2026-06-30 17:18:55.710201+00:00", "lang": "en", "topics": ["developer-tools", "ai-infrastructure", "large-language-models"], "entities": ["RouterBase", "Google", "Gemini 2.5 Flash"], "alternates": {"html": "https://wpnews.pro/news/use-routerbase-as-an-openai-compatible-api-gateway", "markdown": "https://wpnews.pro/news/use-routerbase-as-an-openai-compatible-api-gateway.md", "text": "https://wpnews.pro/news/use-routerbase-as-an-openai-compatible-api-gateway.txt", "jsonld": "https://wpnews.pro/news/use-routerbase-as-an-openai-compatible-api-gateway.jsonld"}}
