v1.9.0

You can also customize the URL that it makes requests to. It defaults to https://openrouter.ai/api/v1 but you can customize it like this:

import { OpenRouter } from "openrouter-client";
// Add `undefined` because JavaScript doesn't have kwargs
// Class constructor() signature is: constructor(apiKey: string, globalConfig?: Types.Config, apiBase?: string)
const OpenRouterClient = new OpenRouter("API key here", undefined, "insert API URL here. Don't leave a trailing slash");
// valid: `https://openrouter.ai/api/v1`
// invalid: `https://openrouter.ai/api/v1/`
//                                       ^ notice the trailing slash. that's what makes it invalid

let nl = await OpenRouterClient.chat([{
    role: "user",
    content: [
        { type: "text", text: "Hello World" },
    ],
}], {
    model: "deepseek/deepseek-r1-0528-qwen3-8b",
});

console.dir(nl);

This works for streaming too. It's literally the same Class constructor signature

v1.8.0

Added "usage": { "include": true } support to the config

v1.7.0

I caught the wrapper up to speed with the current state of OpenRouter's APIs for the most part

Added functionality

• Audio uploads
• Image gen
• Proper plugin support
• Fetch usage data for current API key
• add getGenerationStats and getKeyUsage to OpenRouterStream

Bug fixes

• I forgot to let people upload PDFs when I added PDF support lol
• I forgot to make getGenerationStats send the auth token when I made that function
• OpenRouter changed their API so finish_reason had proper typings in the docs now + added native_finish_reason

Misc

• Types are easier to use now because they're more individually exportable

TODO

• Let users use "usage": { "include": true }
