@sporemesh/browser

Browser client SDK for the live Spore API at https://api.sporemesh.com.

The browser client follows the same product contract as the Python and JS CLIs:

• init
• run
• pause
• status

The only difference is runtime. In the browser, you provide a browser-safe runtime adapter that knows how to mutate and evaluate one experiment locally, while the SDK handles auth, node registration, automatic submission, and challenge state.

The current featured challenge is:

• VIX Regime Classifier Sprint #1
• metric: log_loss
• artifact: classifier.mjs
• dataset: real CBOE VIX daily close history

Install

npm install @sporemesh/browser

Quick start

import {
  createBrowserClient,
  createLocalStorageStore,
  createVixRegimeAdapter,
} from "@sporemesh/browser";

const store = createLocalStorageStore();
const client = createBrowserClient({ store });

await client.init({
  llmProvider: "groq",
  llmApiKey: "<your-key>",
});

console.log(client.status().config.wallet_address);
console.log(client.status().config.default_challenge_slug);

Run continuously with automatic submission:

await client.run({
  intervalMs: 1000,
  adapter: createVixRegimeAdapter(),
});

Pause and inspect state:

client.pause();
console.log(client.status());

Notes

• The SDK stores or reads wallet, API key, LLM settings, and run state only through the storage adapter you provide.
• Browser node metadata is informational only.
• run() submits every experiment result: keep, discard, or crash.
• The adapter decides how an experiment is mutated and evaluated in-browser.
