MercadoLibre Price Tracker & Price History

MercadoLibre price tracker with real price history. Search MercadoLibre (and Mercado Livre Brazil) catalog products in any of 18 Latin American countries and get, for every product, the current best price across all sellers plus its MercadoLibre price history: lowest price ever seen and when, highest price, 24 h and 7 day changes, every price drop as a dated series, and how today's price compares with the historical low. Data comes from the official MercadoLibre API, so there is no HTML scraping, no proxies and no captchas. You pay only per product returned.

Independent tool, not affiliated with MercadoLibre.

Only want alerts when a price drops? See MercadoLibre Price Drop Alerts & Watchlist: give it a watchlist, schedule it, and get only the products that got cheaper.

Selling on MercadoLibre? MercadoLibre Seller Price Monitor tracks your store, distributors or competitors per catalog product: price, rank, gap to the cheapest competitor and MAP violations.

What is MercadoLibre Price Tracker?

MercadoLibre Price Tracker is an Apify Actor that turns MercadoLibre's catalog into a price-history dataset. A MercadoLibre catalog product (the /p/MCO27172677 pages) groups every seller of the same item. For each one, the Actor:

1. Finds the catalog products matching your keywords (e.g. iphone 15 128gb), or takes the product IDs / URLs you give it.
2. Reads every seller offer: price, "original" price, seller, official store, condition, free shipping and listing type.
3. Stores the observation in a shared price-history database.
4. Returns one row per product with the best current price and who sells it, the number of offers, history statistics and, optionally, all offers and the price series.

Products with variants (color, memory, refurbished grade) are tracked one variant at a time, because each variant has its own price.

Why price history matters

A product page says "35 % OFF", but off what? Sellers often raise the "original" price before a sale. The only honest reference is the product's own price history:

• lowestPriceSeen / lowestPriceSeenAt: is today's price really low, or was it cheaper last month?
• realDiscountPct: the current best price against the lowest price ever recorded. 0 means you are at the historical low; -12.5 means you would pay 12.5 % more than the lowest price seen.
• priceChange24h / priceChange7d: did the price just drop, or just go up?
• history: the dated series of best-price changes, ready for a chart.

The history is shared and cumulative: every run, by every user, adds observations to the same series. Popular products in Colombia, Mexico, Argentina and Brazil (phones, consoles, TVs, laptops, appliances) are also refreshed once a day by our own schedules since November 2026, so their history grows every day even if nobody else looks them up.

Use cases

• Price drop alerts. Schedule the Actor with onlyPriceDrops: true and connect an email, Slack or webhook integration: you only receive (and pay for) products whose best price just went down. For thresholds (% or amount) and comparisons against 7 / 30 days ago or the lowest price ever, use MercadoLibre Price Drop Alerts & Watchlist.
• "Is this deal real?" checks. Compare a sale price against lowestPriceSeen and realDiscountPct before buying or before publishing a deal.
• Competitor and marketplace monitoring. Track your own products and your competitors' (productIds) and see every seller, their price, official-store status and free shipping.
• Market research across LATAM. Same product, 18 countries, local currency, number of sellers competing.
• Price charts and dashboards. history is a ready-made time series; export to Google Sheets, BigQuery, Looker Studio or any BI tool.
• AI agents. Let Claude, Cursor or any MCP client answer "what is the cheapest X and is it a good price?" through the Apify MCP server (see below).

How to use it

1. Open the Actor, pick a country and type one or more search keywords (or paste product IDs / URLs).
2. Click Start. A run of a few hundred products takes about a minute.
3. Download the results as JSON, CSV, Excel or HTML, or read them through the API.
4. To build price history for specific products, put them in productIds and add a schedule (e.g. every 12 hours).

Output

One row per catalog product. This is a real, unedited row from the run above (12-nov-2026). The product had been observed 6 times that day and its price had not changed yet, so history holds a single point and the 24 h / 7 d changes are still null:

History statistics (lowestPriceSeen, highestPriceSeen, priceChange*, history) describe the product's best price across all active offers, so the shared history means the same for every user regardless of filters. bestPrice, offersCount and offers respect your filters.

How much does it cost?

Pay per event, no subscription. Platform usage is included.

Event	Price
product-result: one product row in the dataset	$0.0025 ($2.50 / 1,000 products)
history-result: extra for a row whose history carries at least 2 points (includeHistory: true)	$0.0015
Actor start (charged by Apify on every run)	$0.00005 per GB of memory (default 1 GB)

Example: 1,000 products with history ≈ $4.00; 1,000 products without history ≈ $2.50. You are charged only for rows actually written. Set a maximum cost per run in the run options; the Actor stops cleanly when it is reached.

Use the MercadoLibre price tracker from Python

Install the client with pip install apify-client (example tested with apify-client 3.5.1):

from apify_client import ApifyClient

client = ApifyClient("<YOUR_APIFY_TOKEN>")

run = client.actor("pricelatam/mercadolibre-price-tracker").call(run_input={
    "country": "MLM",
    "queries": ["nintendo switch 2"],
    "maxProductsPerQuery": 3,
    "includeOffers": False,
})

for item in client.dataset(run.default_dataset_id).iterate_items():
    print(item["name"], item["currency"], item["bestPrice"],
          "| lowest seen:", item["lowestPriceSeen"], "| 7d change:", item["priceChange7d"])

Real output of that script on 12-nov-2026:

Nintendo Switch 2 + Nintendo Switch Sports Resort MXN 10999 | lowest seen: 10999 | 7d change: None

The same works from JavaScript (apify-client on npm), from any language through the Apify API, and with no code through Make, Zapier, n8n, Google Sheets or webhooks.

Use it from AI agents (Apify MCP server)

The Actor is available as a tool through the Apify MCP server, so Claude, Cursor, VS Code or any MCP client can look up MercadoLibre prices and price history. Add this to your MCP client configuration (OAuth sign-in opens in your browser on first use):

{
  "mcpServers": {
    "mercadolibre-price-tracker": {
      "url": "https://mcp.apify.com?tools=pricelatam/mercadolibre-price-tracker"
    }
  }
}

If your client does not support OAuth, send your token instead with "headers": { "Authorization": "Bearer <YOUR_APIFY_TOKEN>" }.

Then ask, for example: "What is the cheapest iPhone 15 128 GB in Colombia right now, and is it the lowest price you have seen?"

FAQ

Do I need a MercadoLibre account or API key? No. The Actor uses its own MercadoLibre API credentials. You only need an Apify account.

Is this an official MercadoLibre API? The data comes from MercadoLibre's official public API, but this Actor is an independent tool and is not affiliated with MercadoLibre.

How far back does the price history go? The database started collecting in November 2026. Every run by every user adds observations, and popular products in MCO, MLM, MLA and MLB are refreshed daily by our schedules. A product nobody has looked up before starts with one point; schedule it with productIds and its history grows from there.

Why do some products have priceChange24h: null? The product has no observation that old yet. The value appears once the history covers 24 hours (or 7 days for priceChange7d).

What is the difference between listedDiscountPct and realDiscountPct? listedDiscountPct is what the seller claims, based on the "original" price they typed. realDiscountPct compares today's best price with the lowest price we have actually recorded.

Why did I get fewer rows than maxProductsPerQuery? In keyword searches, products with no offer matching your condition / officialStoresOnly filters are skipped and not charged. With productIds, every product is returned, even without offers (bestPrice: null).

Does it cover listings that are not in the catalog? No. It tracks catalog products (/p/… pages), which group all sellers of the same item. Listings outside the catalog are not included.

Do prices include shipping? No. bestPrice is the item price; bestOfferFreeShipping and each offer's freeShipping tell you whether shipping is free.

How often should I schedule it? Every 6–12 hours is enough for most products. Each run adds a point to the history only when the best price changed.

Which countries are supported? All 18 MercadoLibre sites: Argentina, Brazil (Mercado Livre), Mexico, Colombia, Chile, Peru, Uruguay, Ecuador, Venezuela, Bolivia, Paraguay, Dominican Republic, Costa Rica, Nicaragua, Guatemala, Honduras, El Salvador and Panama.

Something does not work. Where do I report it? Open an issue in the Actor's Issues tab with the run ID and the input you used.

Notes

• Prices are the ones published on MercadoLibre at the time of each run.
• Each product is returned once per run, even if several keywords find it.
• More about the data source: MercadoLibre developers.

En español

MercadoLibre Price Tracker busca fichas de catálogo de MercadoLibre (y Mercado Livre en Brasil) en 18 países y devuelve, por ficha, el mejor precio actual entre todos los vendedores y su historial de precios: precio mínimo histórico y cuándo, máximo, cambio en 24 h y 7 días, la serie de bajadas y subidas, y el "descuento real" (precio actual frente al mínimo histórico, no frente al "precio original" que pone el vendedor). Usa la API oficial de MercadoLibre. La historia se acumula con las corridas de todos los usuarios y con nuestras corridas diarias en Colombia, México, Argentina y Brasil. Programa el Actor con productIds para seguir productos concretos, o usa onlyPriceDrops para recibir solo las bajadas de precio. Se paga por producto devuelto. Herramienta independiente, sin relación con MercadoLibre.
