See https://openrouter.ai/docs/guides/community/typesafe-sdk. ## Overview System One endpoints for models such as Jev, compatible with the TypeSafe SDKs. See [https://openrouter.ai/docs/guides/community/typesafe-sdk](https://openrouter.ai/docs/guides/community/typesafe-sdk.md). ### Available Operations * [create](#create) - Submit a System One request ## create Sends state and typed questions to a System One model such as Jev and returns its answers. Compatible with the TypeSafe SDKs. Bare System One model IDs such as `jev-1.13` and `jev-latest` are mapped onto the `typesafe/` namespace. ### Example Usage ```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.systemOne.create({ decisionsRequest: { model: "typesafe/jev-1.13", questions: { "is_bug": { criteria: { false: "The customer is asking a question or requesting a feature.", true: "The customer describes broken or unexpected product behavior.", }, instructions: "Is the customer reporting a software defect?", type: "noul", }, "team": { criteria: { "account": "Login, permissions, or profile issues.", "frontend": "Rendering, layout, or browser compatibility issues.", "payments": "Checkout, billing, or payment processing issues.", }, instructions: "Which team should own this ticket?", type: "choice", }, "urgency": { criteria: [ "Can wait for the next release", "Should be fixed this week", "Blocking revenue right now", ], instructions: "How urgent is this ticket?", type: "score", }, }, state: { "customer_tier": "enterprise", "ticket": "My checkout page shows a blank screen after I click Pay. I have tried two browsers.", }, }, }); console.log(result); } run(); ``` ### Standalone function The standalone function version of this method: ```typescript theme={null} import { OpenRouterCore } from "@openrouter/sdk/core.js"; import { systemOneCreate } from "@openrouter/sdk/funcs/systemOneCreate.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 systemOneCreate(openRouter, { decisionsRequest: { model: "typesafe/jev-1.13", questions: { "is_bug": { criteria: { false: "The customer is asking a question or requesting a feature.", true: "The customer describes broken or unexpected product behavior.", }, instructions: "Is the customer reporting a software defect?", type: "noul", }, "team": { criteria: { "account": "Login, permissions, or profile issues.", "frontend": "Rendering, layout, or browser compatibility issues.", "payments": "Checkout, billing, or payment processing issues.", }, instructions: "Which team should own this ticket?", type: "choice", }, "urgency": { criteria: [ "Can wait for the next release", "Should be fixed this week", "Blocking revenue right now", ], instructions: "How urgent is this ticket?", type: "score", }, }, state: { "customer_tier": "enterprise", "ticket": "My checkout page shows a blank screen after I click Pay. I have tried two browsers.", }, }, }); if (res.ok) { const { value: result } = res; console.log(result); } else { console.log("systemOneCreate failed:", res.error); } } run(); ``` ### Parameters | Parameter | Type | Required | Description | | - | - | - | - | | `request` | [operations.CreateSystemoneRequest](../../models/operations/createsystemonerequest.mdx) | ✔️ | The request object to use for the request. | | `options` | RequestOptions | ➖ | Used to set various options for making HTTP requests. | | `options.fetchOptions` | [RequestInit](https://developer.mozilla.org/en-US/docs/Web/API/Request/Request#options) | ➖ | Options that are passed to the underlying HTTP request.
