Roo Code

Roo Code is a VS Code extension. A VS Code agent with a model for each mode. It has an OpenAI Compatible provider. Set that provider to the exchange. The exchange auctions each request, sets a cap before the first token and charges for the measured use.

Before you start

A workspace with a balance and a spend key. See API keys.
VS Code with Roo Code installed.

1. Choose the provider

Open the provider settings of Roo Code. Choose the OpenAI Compatible provider.

2. Set the base URL

The URL ends in /v1, because Roo Code adds /chat/completions to it.

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

3. Paste the key

sk-liquid-...

4. Set the model

Enter a model name from the book. To get the current names, use GET /v1/models. See Market data.

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.
Use a preset for other purchasing rules. See Purchasing rules.

Troubleshooting

Symptom	Cause and fix
`401`	The key is wrong, revoked or expired. Paste it again.
`404`	Keep `/v1` at the end of the base URL.
`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.

See Errors for the error codes.
