Kimi on RouterHub

# Kimi K3.1 Pro API pricing and setup
Build apps with Kimi using the OpenAI-compatible Chat Completions API, one RouterHub API key, and prepaid credits. Compare published input, output, and cached input rates before choosing your model.

## Kimi models and prices

- [Kimi K3.1 Pro](https://routerhub.si/models/kimi-k3.1-pro) · `kimi-k3.1-pro`
- [Kimi K3.1 Pro Uncensored](https://routerhub.si/models/kimi-k3.1-pro-uncensored) · `kimi-k3.1-pro-uncensored`
See [Models & pricing](https://routerhub.si/models) for current model IDs, rates, availability, and limits. These details can change; use that page before sending a request.
Input is the prompt you send; output is the response you receive. Cached input rates apply when the provider reports a cache hit. Prices come from RouterHub's current public catalogue; these are RouterHub rates. No separate subscription is required.

## Get an API key

- [Create a RouterHub account](https://routerhub.si/register?model=kimi-k3.1-pro).
- [Add prepaid credits](https://routerhub.si/dashboard/billing).
- [Create an API key](https://routerhub.si/dashboard/keys) and keep it in your local environment.
- Send a short Chat Completions request, then check [Usage](https://routerhub.si/dashboard/usage) for its cost.

## Send your first Kimi API request
Use the exact model ID `kimi-k3.1-pro` with `https://routerhub.si/v1/chat/completions`. Set `ROUTERHUB_API_KEY` in your local environment. This request uses prepaid credits.

### cURL

```
curl --connect-timeout 30 --max-time 600 https://routerhub.si/v1/chat/completions \
  -H "Authorization: Bearer $ROUTERHUB_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"kimi-k3.1-pro","messages":[{"role":"user","content":"Reply with OK."}]}'
```

### Python
Install the OpenAI Python SDK with `pip install openai`.

```
import os
from openai import OpenAI

client = OpenAI(
    api_key=os.environ["ROUTERHUB_API_KEY"],
    base_url="https://routerhub.si/v1",
    timeout=600.0,
)
response = client.chat.completions.create(
    model="kimi-k3.1-pro",
    messages=[{"role": "user", "content": "Reply with OK."}],
)
print(response.choices[0].message.content)
```

### Node.js
Install the OpenAI JavaScript SDK with `npm install openai`.

```
import OpenAI from "openai";

const client = new OpenAI({
  apiKey: process.env.ROUTERHUB_API_KEY,
  baseURL: "https://routerhub.si/v1",
  timeout: 600000,
});
const response = await client.chat.completions.create({
  model: "kimi-k3.1-pro",
  messages: [{ role: "user", content: "Reply with OK." }],
});
console.log(response.choices[0].message.content);
```
Python SDK timeouts use seconds; JavaScript SDK timeouts use milliseconds. Both examples allow ten minutes per attempt. SDKs may retry automatically; check Usage and the request ID before manually rerunning a timeout.
