@reasoningco/infer

TypeScript SDK that turns natural language questions into safe, parameterized SQL — powered by LLMs, locked down by an 8-layer security pipeline.

Install

npm install @reasoningco/infer

Usage

import { Infer, PostgresConnector } from '@reasoningco/infer';

const infer = new Infer({
  connector: new PostgresConnector({
    connectionString: process.env.DATABASE_URL,
  }),
  llm: { provider: 'openrouter', apiKey: process.env.LLM_API_KEY },
  tenantId: 'tenant_123',
});

const result = await infer.ask('revenue by month last quarter');
console.log(result.rows);

await infer.close();

Security

Every query passes through 8 layers before touching your database:

Input validation → LLM planner → Plan validator → Entity resolver → SQL compiler → SQL validator → Secure executor → Result sanitizer

LLM Providers

OpenRouter, OpenAI, Anthropic, and Ollama supported out of the box.
