## LLM API endpoints

Base URL: `https://runapi.ai`

- `POST /v1/embeddings` — OpenAI Embeddings
- `POST /v1/chat/completions` — OpenAI compatible
- `POST /v1/responses` — OpenAI Responses
- `POST /v1/messages` — Anthropic compatible
- `POST /v1beta/models/{model}:generateContent` — Gemini generateContent
- `POST /v1beta/models/{model}:streamGenerateContent` — Gemini streamGenerateContent

Use a compatible SDK for the endpoint you call with your RunAPI API key.

## Install a model skill

```sh
npx skills add runapi-ai/<line> -g
```

Replace `<line>` with a model slug from this provider, then use the skill docs, schemas, pricing notes, and setup steps while adding the model feature.

## FAQ

### 這是 OpenAI 的官方整合嗎？

RunAPI 提供託管 API 介面，價格、能力及錯誤行為都清晰透明。

### 我需要 OpenAI 帳戶嗎？

不用 — 你的 RunAPI 密鑰已足夠使用託管存取。

### 透過 proxy 會增加多少延遲？

通常少於 20 ms。RunAPI 會將 proxy 層維持在貼近 model 執行區域的位置。

### 圖片／影片會快取嗎？

生成結果會按 task ID 儲存並可供取回。輸入內容不會快取。

### 我可以使用自己的 key 嗎？

目前不支援 — 請使用 RunAPI 管理的存取。
