"", }); async function run() { const result = await openRouter.responses.send({ responsesRequest: {}, }); console.log(result); } run(); ``` ### Standalone function The standalone function version of this method: ```typescript theme={null} import { OpenRouterCore } from "@openrouter/sdk/core.js"; import { responsesSend } from "@openrouter/sdk/funcs/responsesSend.js"; // Use `OpenRouterCore` for best tree-shaking performance. // You can create one instance of it to use across an application. const openRouter = new OpenRouterCore({ httpReferer: "", appTitle: "", appCategories: "", apiKey: process.env["OPENROUTER_API_KEY"] ?? "", }); async function run() { const res = await responsesSend(openRouter, { responsesRequest: {}, }); if (res.ok) { const { value: result } = res; console.log(result); } else { console.log("responsesSend failed:", res.error); } } run(); ``` ### Example Usage: insufficient-permissions ```typescript theme={null} import { OpenRouter } from "@openrouter/sdk"; const openRouter = new OpenRouter({ httpReferer: "", appTitle: "", appCategories: "", apiKey: process.env["OPENROUTER_API_KEY"] ?? "", }); async function run() { const result = await openRouter.responses.send({ responsesRequest: {}, }); console.log(result); } run(); ``` ### Standalone function The standalone function version of this method: ```typescript theme={null} import { OpenRouterCore } from "@openrouter/sdk/core.js"; import { responsesSend } from "@openrouter/sdk/funcs/responsesSend.js"; // Use `OpenRouterCore` for best tree-shaking performance. // You can create one instance of it to use across an application. const openRouter = new OpenRouterCore({ httpReferer: "", appTitle: "", appCategories: "", apiKey: process.env["OPENROUTER_API_KEY"] ??
