Chile Public Procurement Data — Mercado Público Scraper

Scrape public procurement records from Mercado Público, Chile's national ChileCompra purchasing platform. Returns tenders with buyer details and award outcomes, plus the purchase orders — including convenio-marco catalog orders — that never show up as a tender at all.

Mercado Público Scraper Features

• Extracts open tenders across every status — published, closed, awarded, void, revoked
• Follows through to the award: winning supplier, awarded amount, and bidder count on top of the base listing
• Returns purchase orders separately, the channel a large share of Chilean state spend moves through and most tender-only tools never touch
• Flags which purchase orders came off a convenio-marco framework catalog rather than a one-off award
• Includes buyer and supplier RUT (Chilean tax id) on every record, so output joins cleanly against company registries
• Classifies line items by UNSPSC product code, not just a free-text title
• Filters by date range — a single day or a multi-year backfill run the same code path

Who Uses Mercado Público Data?

• Sales and BD teams — find every government unit buying in a product category before a competitor does
• Market researchers — track award amounts and winning suppliers across a sector, or benchmark against Chile's broader public spend
• Compliance and audit teams — monitor a specific buyer unit or supplier's contract history over time
• Suppliers and bidders — compute a win rate against named competitors instead of guessing from headline totals
• Data teams building LATAM company graphs — the RUT fields join directly against other Chilean company data

How the Mercado Público Scraper Works

1. Pick a date range and which record types you want — tenders, purchase orders, or both.
2. The scraper pulls the day's full listing, then fetches each record's detail — buyer info, line items, and (for tenders) the award outcome.
3. Records come back as clean, flat JSON: one row per tender or purchase order, with consistent field names across both.
4. A large date range keeps going past maxItems; resume it in a later run instead of paying for the whole thing again.

Input

{
  "ticket": "your-mercadopublico-api-ticket",
  "recordTypes": ["tenders", "purchase_orders"],
  "dateFrom": "2026-09-01",
  "dateTo": "2026-09-07",
  "maxItems": 500
}

Field	Type	Default	Description
ticket	String	shared public demo ticket	Your free Mercado Público API ticket (recommended). Register at mercadopublico.cl (Empresas > API) — issued instantly, no cost. Leave empty to use ChileCompra's shared public demo ticket.
recordTypes	Array	["tenders", "purchase_orders"]	Which record families to pull: tenders (licitaciones), purchase_orders (órdenes de compra), or both.
dateFrom	String	yesterday	First day to pull, inclusive (YYYY-MM-DD). Mercado Público publishes per calendar day.
dateTo	String	same as dateFrom	Last day to pull, inclusive (YYYY-MM-DD). Widening the range costs one extra listing call per day.
maxItems	Integer	20	Maximum combined records to save. Each record costs one detail call on top of the listing.

Resuming a large crawl

Every run emits a resumeCursor in its Output. If a large crawl stops before it finishes — because it hit maxItems, your spend cap (maxTotalChargeUsd), or was aborted — start a new run with the same input plus that resumeCursor to continue from where it left off. The crawl resumes from the queued work the previous run didn't reach.

• You are not re-charged for records the earlier run already delivered.
• Resume within your account's run-retention window — on the free tier, roughly your 10 most recent runs. Once the source run is pruned, its resumeCursor is no longer valid.
• resumeCursor is opaque — supply it unmodified.

FAQ

How do I scrape Mercado Público tenders and purchase orders?

Give Mercado Público Scraper a date range and it returns tenders, purchase orders, or both. For regular use, register a free API ticket at mercadopublico.cl and paste it into the ticket field.

Do I need an account or API key for Mercado Público?

No, but your own is recommended. Left empty, the scraper uses ChileCompra's shared public demo ticket, and every caller without a ticket shares its rate limit. Your own ticket costs nothing, is issued instantly through Mercado Público's registration page, and carries its own limit.

Can I get award and bidder data, not just open tenders?

Yes. Every tender record carries the award outcome once one exists — winning supplier, awarded amount, and bidder count — which is exactly the part most tender-list tools stop short of.

What's the difference between tenders and purchase orders?

Tenders (licitaciones) are the open-bid process. Purchase orders (órdenes de compra) are the actual spend — including convenio-marco catalog purchases that skip the tender process entirely. A tender-only view misses that spend.

Can I pull historical data, not just recent tenders?

Yes. Set dateFrom and dateTo to any range; a run that hits its item cap on a wide range picks back up with resumeCursor instead of starting over.

Why Use Mercado Público Scraper?

• Complete, not partial — tenders, awards, bidders, and purchase orders in one feed, where most alternatives stop at the open-tender list.
• Joinable by design — buyer and supplier RUT on every record means the output slots straight into a Chilean company graph or registry match, no manual entity resolution.
• Covers the spend tender-only tools miss — convenio-marco purchase orders are flagged explicitly, and they're where a large share of Chilean public spend actually happens.
