Licitaciones Feed — Buenos Aires Public Procurement Tenders

Pay-per-event — zero monthly fee, zero subscription. Search and monitor public tenders Argentina from Buenos Aires Compras (BAC) — the official procurement platform for the City of Buenos Aires. Track licitaciones and compras publicas with OCDS-structured data, keyword search, and sync mode for new tenders. Pay per matched tender. No rental. No idle fees.

What it does

This actor provides a searchable feed of licitaciones CABA (Buenos Aires City government procurement tenders — not national) from the official Buenos Aires Compras open-data CSV. It serves two use cases in one actor: ad-hoc keyword search (query mode) and scheduled monitoring (sync mode) that detects only new tenders since your last run. Source data is CC-BY-4.0 licensed and published quarterly on the Buenos Aires government CDN — fully compliant, no proxy needed, no anti-bot risk. There are 2 other procurement actors covering Argentina: karmic_mastodon/licitaciones-latam (5 users, covers 6 LATAM countries including Argentina) and our own BAC-specific focus.

If you're looking for Buenos Aires City procurement data specifically, this gives you structured JSON with OCDS identifiers, procuring entities, amounts, deadlines, and tender categories at pay-per-event pricing. Integrate it with your supplier lead-gen pipeline for pennies per result.

How it works

Two modes:

query (default)

Downloads bac_anual.csv (~55MB), parses all records, applies your filters (keywords, buyer, amount range, status, date range), and returns matching tenders. Each returned tender triggers a tender-matched event charge.

sync

Downloads bac_anual.csv, compares it against stored KVS state (licitaciones-feed-state). If the file hasn't changed (same Last-Modified header), exits with "no new data". If changed, returns only the new OCIDs (tenders not seen in previous runs) and updates the KVS. Each new tender triggers a tender-new event charge.

Pricing

This actor uses pay-per-event pricing. You are never charged for zero-result queries, unchanged sync runs, or failed downloads.

Event	Price	When charged
tender-matched	$0.007	Per tender returned in query mode (no charge for 0 results)
tender-new	$0.02	Per new tender detected in sync mode

At $0.007–0.02 per tender, a 500-tender query costs $3.50–10. Monitoring licitaciones CABA weekly costs well under $1/month even in active periods.

---

Use cases

• Procurement monitoring — daily sync to catch new licitaciones and compras publicas in Buenos Aires
• Market research — keyword-search active tenders by category or buyer across public tenders Argentina (CABA)
• Supplier lead gen — find tenders matching specific goods/services; plug into your proveedores del estado pipeline
• Agent / LLM tool — plug into an MCP toolchain for contrataciones del estado and government procurement Argentina data

---

Use with AI agents (MCP)

This actor is available as a tool for AI assistants via the Apify MCP server. Agents can call it to search Buenos Aires public procurement tenders directly — no Apify console needed, just a single function call.

MCP setup

{
  "mcpServers": {
    "apify": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "https://mcp.apify.com?tools=mfapitools/licitaciones-feed",
        "--header",
        "Authorization: Bearer <YOUR_API_TOKEN>"
      ]
    }
  }
}

Example agent prompts

• "Find all active IT services tenders from Buenos Aires Compras"
• "Check for new licitaciones in CABA since yesterday"
• "Pull all procurement tenders from the Buenos Aires health ministry over $1M ARS"

The actor returns structured OCDS JSON with the same fields shown above. Agentic workflows (Claude Code, Cursor, any MCP-compatible AI) can search government procurement Argentina tenders and match them against your product catalog in the same run.

Slack / Discord alerts

Set slackWebhookUrl and/or discordWebhookUrl in the input and the actor will POST a compact summary at the end of any run that returns matched (query) or new (sync) tenders — no extra actor, no polling, no Apify task webhook config needed. This is the natural pairing for sync mode on a daily schedule: run it once a day and get pinged only when something new shows up.

Behavior guarantees:

• Leave both fields empty → zero change in behavior, no network calls.
• By default, a run with zero matched/new tenders sends no notification. Set notifyOnEmpty: true to also get a "nothing found" ping (useful to confirm your schedule is still alive).
• A webhook failure (bad URL, channel deleted, Slack/Discord outage) is logged as a warning and never fails the run — your dataset output and PPE charge are unaffected either way.
• Only up to 5 tenders are listed by name in the message body (the rest are summarized as "+N más" — the full list is always in the Apify dataset).
• Amount totals only count tenders with amount > 0, since BAC frequently reports 0.0 — the message says how many of the listed tenders had a real amount.

Setup: Slack

1. Go to api.slack.com/apps → Create New App → From scratch.
2. Pick a name (e.g. "Licitaciones CABA") and your workspace.
3. In the app's sidebar, open Incoming Webhooks → toggle it On.
4. Click Add New Webhook to Workspace, pick the channel, Allow.
5. Copy the URL (looks like https://hooks.slack.com/services/T000/B000/XXXXXXXX) into this actor's slackWebhookUrl input field.

Setup: Discord

1. In Discord, open the target channel's Settings → Integrations → Webhooks.
2. Click New Webhook, name it, pick the channel, Copy Webhook URL.
3. Paste the URL (looks like https://discord.com/api/webhooks/000000/XXXXXXXX) into this actor's discordWebhookUrl input field.

Both fields are marked as secret inputs on the Apify platform (masked in the console UI and encrypted at rest) — but treat the URL like a password regardless: anyone who has it can post messages to your channel.

Example message (Slack, sync mode, 2 new tenders)

🆕 2 licitaciones nuevas — Buenos Aires Compras (BAC)
Monto total (1 con monto informado): $2.500.000 ARS

• Señales de Radio
• Mantenimiento Edilicio — $2.500.000 ARS

Limitations (v1)

• Data lag (critical): BAC publishes quarterly; the CSV on CDN may lag 7–17 weeks behind live tenders. This is a historical search / slow alert product, not a real-time feed.
• CABA only: no national COMPR.AR (ToS conflict), no Mendoza (6.5 months stale).
• Amounts often 0.0: many BAC entries have tender/value/amount = 0.0. Filter with caution.
• No award/contract data: v1 covers only the tender stage (awards/contracts live in bac.csv, 2.5GB — v2 candidate).
• Webhook alerts are best-effort: Slack/Discord delivery never blocks or fails a run (see Slack / Discord alerts above); the Apify dataset is always the source of truth.
• No items flattening: nested tender/items data is skipped in v1.
