# Cherry Studio

Cherry Studio is a desktop chat client. Add the exchange as an OpenAI-compatible provider, set the API host and paste your key. Cherry Studio then sends its requests to the exchange.

## Before you start

- A workspace with a balance and a `spend` key. See [API keys](https://inference.ai.exchange/docs/keys.md).
- Cherry Studio installed.

## 1. Add a provider

Open **Settings → Model Providers → Add**. Choose the OpenAI-compatible provider type and give the provider a name.

## 2. Set the API host

```
https://router.inference.ai.exchange/v1
```

The URL ends in `/v1`.

## 3. Paste the key

```
sk-liquid-...
```

## 4. Add the model

Add a model name from the book. To get the current names, use `GET /v1/models`. See [Market data](https://inference.ai.exchange/docs/market.md).

```
liquid.auto
```

## Notes

- The exchange sets a cap on each request. It is in the `x-liquid-cap-usd` response header. To limit total spend, set a spending limit on the key. See [API keys](https://inference.ai.exchange/docs/keys.md).
- Use a preset for other purchasing rules. See [Purchasing rules](https://inference.ai.exchange/docs/rules.md).

## Troubleshooting

| Symptom                                 | Cause and fix                                                                  |
| --------------------------------------- | ------------------------------------------------------------------------------ |
| `401`                                   | The key is wrong, revoked or expired. Paste it again.                          |
| `404`                                   | Keep `/v1` at the end of the API host.                                         |
| `model_not_found`                       | The model is not on the book. Use an exact name from `GET /v1/models`.         |
| A request is refused for lack of funds. | The workspace balance cannot cover the cap. Add funds on the **Credits** page. |
