4 commands. 38 retailers. 8 countries. Your agent just learned how to shop. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ You’re building an AI agent. It can search the web, reason about complex topics, generate code. But when it needs to answer a simple question like “how much does rice cost in Lima today?” — it hits a wall. Not because it’s dumb. Because every retailer has a different API, auth mechanism, schema, and checkout flow. There’s no Stripe for commerce data. Until now. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ '''bash

1. Install

pip install cli-market-world

2. Guided first search + interactive tutorial

market init # login + first query market tutorial # 3 exercises: search, compare, export — 60 seconds

3. Search — your agent just queried 38 retailers in <1s

market search “leche” —country PE —json

4. Connect to your AI agent via MCP

Add to Cursor / Claude / any MCP client:

'''

That’s the entire integration. No API keys per retailer. No HTML scraping. No schema mapping. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ When your agent runs market search “rice” —country PE —json, CLI Market: Normalizes the query — “arroz”, “rice”, “arroz blanco” all map to the same product Queries our collector — 38 active retailers, refreshed every 4 hours Returns structured JSON — price per kg/L, store name, country, timestamp Handles auth — one CLI Market token, not 38 retailer tokens What it looks like in your terminal: ![CLI Market terminal output — 60 seconds, real prices] '''json { “query”: “arroz”, “country”: “PE”, “results”: [ { “product”: “Arroz Extra 5kg”, “price”: 18.90, “price_per_kg”: 3.78, “store”: “Wong”, “country”: “PE”, “refreshed_at”: “2026-06-10T08:00:00Z” } ] } '''

━━━━━━━━━━━━━━━━━━━━━━━━━━━━ CLI Market exposes 22 curated MCP tools (46 legacy) — search, compare, basket, checkout paths — so your agent can: Search products across all retailers Compare prices between stores Filter by country, category, or price range Get historical price data (Pro tier) Connect in Cursor or any MCP client in 30 seconds. Configuration at cli-market.dev/tools. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Price monitoring agents — track commodity prices across LATAM Shopping assistants — “find the cheapest 5kg rice in Lima” Competitive intelligence — benchmark your retail prices against the market Supply chain optimization — auto-reorder when prices drop below threshold ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ We’re working on cart + checkout — so your agent doesn’t just search, it buys. One API call to add to cart across any supported retailer. Start building: '''bash pip install cli-market-world market init '''
