You need to set OPENROUTER_API_KEY to your API key.

    {
        openrouter = {
            prepare_input = require('CopilotChat.config.providers').copilot.prepare_input,
            prepare_output = require('CopilotChat.config.providers').copilot.prepare_output,

            get_headers = function()
                local api_key = assert(os.getenv('OPENROUTER_API_KEY'), 'OPENROUTER_API_KEY env not set')
                return {
                    Authorization = 'Bearer ' .. api_key,
                    ['Content-Type'] = 'application/json',
                }
            end,

            get_models = function(headers)
                local response, err = require('CopilotChat.utils').curl_get('https://openrouter.ai/api/v1/models', {
                    headers = headers,
                    json_response = true,
                })

                if err then
                    error(err)
                end

                return vim.iter(response.body.data)
                    :map(function(model)
                        return {
                            id = model.id,
                            name = model.name,
                        }
                    end)
                    :totable()
            end,

            get_url = function()
                return 'https://openrouter.ai/api/v1/chat/completions'
            end,
        },
    }
