Build on the LQM operating system.
Discover and execute Large Quantitative Models, compose quantitative systems, run LQBench, connect governed data, verify outputs, guard actions and record observed outcomes through one shared platform contract.
First execution
From API key to LQM run in minutes.
Use least-privilege server-side credentials. Every major operation carries model identity, lineage, quantitative evidence and request metadata.
import { LargeQuant } from "@largequant/sdk";
const lq = new LargeQuant({
apiKey: process.env.LARGEQUANT_API_KEY
});
const run = await lq.models.execute(
"lqm-finance-1",
{ input: { values: [1, 2, 3] } },
{ idempotencyKey: "first-run-001" }
);
Official SDK programme
LargeQuant wherever software is built.
Tier‑1 packages share the same OpenAPI 3.1 contract, typed errors, idempotency support, webhook verification and configurable environments.
