The VTEX public API is the same for 3,760 retailers — but no one aggregated it. Until now.

VTEX runs e-commerce for Nike, Carrefour, Samsung, Motorola, and 3,760+ other brands. Every one exposes the same search and catalog API endpoints. Same JSON schema. Same pagination rules.

For years, if you wanted to query products across retailers, you had to scrape or make separate API calls per store. There was no aggregation layer.

VTEX powers e-commerce for Nike, Carrefour, Samsung, and 3,760+ brands.
All share the same public API — but no one had built the aggregation layer for programmatic access. Until now.

pip install cli-market and your terminal becomes a commerce engine across 67 countries.

So I built one.

Technical details:

Single Python connector that maps VTEX's public search/catalog/checkout endpoints
Each retailer = one config line: {domain, country, currency, line}
SQLite price snapshots for historical data
Rich terminal UI + REST API + MCP server (12 tools)
JSON output saves ~85% context window tokens vs raw HTML

Everything is indexed and queryable cross-retailer. Search "milk" and get results from Carrefour Brazil, Sainsbury's UK, Wong Peru, in one response.

Curious what the community thinks about e-commerce APIs being still optimized for browsers instead of programmatic access.

En este post te presento CLI Market, una infraestructura de comercio open source que conecta 100 retailers en 12 países de LATAM a través de una sola API y una CLI para agentes de IA.

¿Qué es CLI Market?
CLI Market unifica catálogos, precios y disponibilidad de múltiples retailers para que tus agentes de IA puedan buscar, comparar y simular compras sin integrar tienda por tienda.

2000+ retailers conectados
40+ países en el mundo
Una API y una CLI open source

👉 Sitio: https://cli-market.dev/
👉 Repo: https://github.com/Treevu-ai/cli-market-world

Cómo empezar?

git clone https://github.com/Treevu-ai/cli-market-latam.git
cd cli-market-latam
npm install
npm run cli

Ejemplo rápido para listar retailers por país:

cli-market retailers list --country=PE

Con esto ya puedes exponer catálogos como herramientas para tus agentes (HTTP, JSON, MCP) y construir asistentes que optimicen compras en retail sobre una sola capa de infraestructura.

One of the most powerful things I've learned a few days ago is the possibilities to vibe coding from ubuntu and docker containers
