OpenRouter代替品
OpenRouter lets you swap the model behind Claude Code and other tools by changing ANTHROPIC_BASE_URL — 300+ language models, some with free tiers. RunAPI does the same base URL swap, adds image, video, music, and audio (230+ models total), and charges 50% off official rates with no deposit required to avoid rate limits. Both expose an OpenAI-compatible API.
Key takeaways
-
Both expose an OpenAI-compatible API. Changing the base URL and swapping the key is usually the only change required.
-
OpenRouterはLLMのみです。RunAPIは同じキーの下に画像、動画、音楽、オーディオ生成を追加します。
-
OpenRouter’s free tier caps at 50 requests per day without a $10 deposit. RunAPI is pay-as-you-go with no free tier and no request cap.
- 230+ モデル
- 5 モダリティ
- 15-25% コスト削減

Is this actually free or do you pay with your data?
RunAPI does not train on your requests and does not log prompt content for model improvement. Free models on OpenRouter are hosted by third-party providers under OpenRouter’s terms — those providers’ data policies apply. If you are routing client data or sensitive code, check the data policy of every provider in the chain, not just the gateway.
Don’t you need $10 of credit loaded to use free models? Otherwise you only get 50 requests/day instead of 1,000.
OpenRouter throttles accounts with $0 balance to 50 requests per day on free models. Depositing $10 raises that to 1,000 requests per day. RunAPI has no free inference tier, so there is no deposit requirement or request-cap — you pay per token at 50% of official rates from the first call.
What about rate limiting — the videos didn't mention it?
Free models on OpenRouter are rate-limited and queue behind paid traffic. When you pin to a single free model you can hit the cap fast; the openrouter/auto endpoint spreads load across available free models to reduce that. RunAPI has no free tier, so all paid requests go through without queuing behind free traffic.
Does RunAPI work with Claude Code and Cursor?
Yes. Set ANTHROPIC_BASE_URL to https://runapi.ai/v1 and use your RunAPI key as ANTHROPIC_API_KEY. The Claude Code shell — its agentic framework, slash commands, and tool calls — stays the same. You are changing the model that processes the prompts, not the client itself.
Do I need to rewrite my code to switch from OpenRouter to RunAPI?
No. Both platforms expose an OpenAI-compatible API, so switching is a base URL and key change in your existing client. Point your client at https://runapi.ai/v1, swap in your RunAPI key, and keep the rest of your code as-is. You can run both in parallel during testing.
How much cheaper is RunAPI versus paying OpenRouter directly?
RunAPI charges 50% of each provider's official published rate. Claude Sonnet 4.6 runs $3 input and $15 output per million tokens versus $6 and $30 official; GPT-5.4 runs $1.25 input and $7.50 output versus $2.50 and $15. Image, video, and audio are billed per task at the same half-off positioning.
What developer tools does RunAPI include that OpenRouter lacks?
RunAPI ships an MCP server for MCP-aware tools like Claude Code and Cursor, a command-line tool, typed SDKs for Python, Node.js, PHP, Java, Ruby, and Go, installable agent skills, and a searchable prompt library. OpenRouter provides an OpenAI-compatible API and a web UI but does not include these additional tooling layers.
How many models does RunAPI support compared to OpenRouter?
RunAPI covers LLMs from Claude, GPT, and Gemini families plus image, video, music, and audio generation — 230+ models in total. OpenRouter routes 300+ language models including many open-source and community models, but covers text only. If you need free or open-source LLM access at volume, OpenRouter has more options there.
