Install

npm install -g latinfo
latinfo login

latinfo login opens GitHub OAuth in your browser and stores your API key in ~/.latinfo/config.json. Takes 30 seconds.

CLI

latinfo ruc 20100047218           # Lookup by RUC
latinfo dni 12345678              # Lookup by DNI (converts to RUC automatically)
latinfo search "banco de credito" # Search by company name
latinfo ruc 20100047218 --json    # JSON output (for scripts and AI agents)

No login needed for demo data (~95 embedded records). Run latinfo login for 18M+ records.

npm install latinfo

import { Latinfo } from 'latinfo';

const client = new Latinfo('YOUR_API_KEY');

// Lookup by RUC

What you don't have to do

You don't download 364MB from SUNAT. You don't parse Latin1 with escaped pipe delimiters. You don't write a check digit algorithm. You don't build a search index that handles S.A.C. and E.I.R.L. You don't set up a daily import pipeline. You don't manage servers.

We do all of that. Daily.
