Cordoba Argentina Licitaciones - Tender Delta API

A Cordoba, Argentina government procurement (compras públicas) monitor that turns a stateful, session-bound tenders portal into a clean, delta-aware public tenders dataset, on a schedule you configure.

What it does

Checking the Province of Córdoba's official compras públicas portal by hand means clicking through a paginated, stateful ASP.NET grid and re-reading every row yourself to notice what changed. Cordoba Argentina Licitaciones - Tender Delta API does that walk programmatically and hands back a structured public tenders dataset: tender number (nroCotizacion), contract type, issuing organism, jurisdiction, publication and closing dates, status (estado), per-item reference budget, and contact phone — one record per active licitación, already parsed from the source's own listing fetch.

Where this actor earns its keep as a public tenders API alternative for Córdoba is delta mode. With onlyNew enabled, it persists which tenders it has already seen — and their last-known status and a content fingerprint — in a key-value store that survives between scheduled runs, and on every subsequent run reports only what actually changed: a brand-new listing, a status change, an amendment (a deadline extension, a revised budget), or a closure. That is the difference between a one-off scrape and a Córdoba government procurement monitor a contractor, gestor, or market-research team can put on a schedule and trust to flag changes on its own.

The scope is deliberately exact: this actor covers the active Licitaciones register published by webecommerce.cba.gov.ar, nothing broader and nothing historical. Awarded or archived tenders are out of scope, by design, because the source itself does not expose them through this portal.

Who uses this

• Contractors and suppliers bidding on Córdoba public works and services — pull the active register and use tipoContratacion and servicioAdministrativo on each record to spot the tenders that match what they sell and who's buying, with prorroga and STATUS_CHANGE flagging a tracked deadline extension without refreshing the portal.
• Market-entry research teams evaluating the Córdoba public sector — a full run (onlyNew: false) surfaces which agencies are actively procuring, and at what reference budget, via servicioAdministrativo, jurisdiccion, and items[].presupuestoOficial.
• Procurement consultants and gestores tracking several clients' tenders at once — a scheduled run with onlyNew: true returns only NEW_LISTING, STATUS_CHANGE, UPDATED, or CLOSED across every tracked nroCotizacion, instead of manually re-checking each client's tenders one by one.

Cost & BYOK Disclosure

Pricing model: pay per event, platform usage included — there is no separate compute charge on top.

Event	What triggers it	Price
result	A tender is delivered as NEW_LISTING, STATUS_CHANGE, or UPDATED — full tender content	Pay-per-result — see the live Store pricing tab for the current exact rate
result-summary	A tender is delivered as CLOSED — a derived absence signal, nothing fresh to fetch	Pay-per-result — see the live Store pricing tab for the current exact rate
Actor start	Once per run, regardless of how many tenders are returned	See the live Store pricing tab for the current exact rate

Specific per-event rates have appeared in this Actor's own Store listing and in earlier README revisions; the Store's Pricing tab is the single, always-current source of truth, so it's linked above rather than a number restated here that could drift out of date. Recurring monitoring with onlyNew: true costs less per run by construction: it only ever delivers what actually changed since the last run, instead of billing result for every unchanged tender in the register every time.

Delta suppression, never a refund. A tender whose estado and content fingerprint both match what was already delivered is classified UNCHANGED and is never pushed to the dataset — the fingerprint comparison against the persisted key-value store happens before delivery on every run, so an unchanged tender is simply never billed, not refunded after the fact.

BYOK: This Actor requires no third-party API key. It does require a Residential + Argentina Apify Proxy group (defaulted automatically even if proxyConfiguration is omitted) because the source blocks non-residential, non-Argentina traffic — that proxy is billed through your own Apify platform usage, not a separate third-party key you supply.

Features

Feature	Description
Delta mode (onlyNew)	Persists seen tender ids, their estado, and a content fingerprint in a named key-value store across scheduled runs; returns only what changed instead of the full register every time.
Event classification	Every delivered record is tagged NEW_LISTING, STATUS_CHANGE, UPDATED, or CLOSED (eventTypes narrows which of these delta mode delivers).
Stateful ASP.NET pagination handled correctly	Replicates the portal's postback/ViewState grid exactly as a real browser would, including its 11-slot sliding pager window, rather than treating it as a simple paged URL.
Mid-run dedup against live inserts	Every walked row is deduplicated by nroCotizacion, so a tender published while a multi-page walk is already in progress can't produce duplicate records.
Residential Argentina proxy, defaulted	The source blocks non-residential, non-Argentina traffic at the network level; the actor defaults to Residential + AR proxy even if proxyConfiguration is omitted entirely.
Recency filter (dateRange)	Optionally restricts results to tenders published in the last 24h, 7d, or 30d, independent of delta mode.
Inline line-item extraction	Each tender's items (renglon, quantity, reference price, official budget) are extracted from the listing fetch itself — no per-tender follow-up request.

Quickstart

Run it directly with the Apify CLI, the REST API, or the apify-client SDK in Python or Node.js.

Apify CLI

apify call cordoba-compras-monitor --input '{
  "maxItems": 200,
  "onlyNew": true,
  "eventTypes": ["NEW_LISTING", "STATUS_CHANGE", "UPDATED", "CLOSED"],
  "dateRange": "7d",
  "proxyConfiguration": {
    "useApifyProxy": true,
    "apifyProxyGroups": ["RESIDENTIAL"],
    "apifyProxyCountry": "AR"
  }
}'

cURL (instant, synchronous)

Runs synchronously and returns the resulting dataset items directly in the response - no polling needed. Get your token from console.apify.com/settings/integrations.

curl -X POST "https://api.apify.com/v2/acts/q9jhMgJRSGjyNbXKA/run-sync-get-dataset-items?token=<YOUR_API_TOKEN>" \
  -H "Content-Type: application/json" \
  -d '{
  "maxItems": 50,
  "onlyNew": true
}'

Python (apify-client)

import os
from apify_client import ApifyClient

client = ApifyClient(os.environ["APIFY_TOKEN"])

run = client.actor("stefano_seggio/cordoba-compras-monitor").call(
    run_input={
        "maxItems": 100,
        "onlyNew": True,
        "eventTypes": ["NEW_LISTING", "STATUS_CHANGE", "UPDATED", "CLOSED"],
        "dateRange": "7d",
        "proxyConfiguration": {
            "useApifyProxy": True,
            "apifyProxyGroups": ["RESIDENTIAL"],
            "apifyProxyCountry": "AR",
        },
    }
)

for item in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(f"{item['nroCotizacion']} [{item['event_type']}] {item['servicioAdministrativo']} - {item['estado']}")

A full runnable version of this script is at examples/run_monitor.py in this repo.

Node.js (apify-client)

import { ApifyClient } from 'apify-client';

const client = new ApifyClient({ token: process.env.APIFY_TOKEN });

const run = await client.actor('stefano_seggio/cordoba-compras-monitor').call({
  maxItems: 100,
  onlyNew: true,
  eventTypes: ['NEW_LISTING', 'STATUS_CHANGE', 'UPDATED', 'CLOSED'],
  dateRange: '7d',
  proxyConfiguration: {
    useApifyProxy: true,
    apifyProxyGroups: ['RESIDENTIAL'],
    apifyProxyCountry: 'AR',
  },
});

const { items } = await client.dataset(run.defaultDatasetId).listItems();
for (const item of items) {
  console.log(`${item.nroCotizacion} [${item.event_type}] ${item.servicioAdministrativo} - ${item.estado}`);
}

A full runnable version (CommonJS) is at examples/run-monitor.js in this repo.

Use this from Claude Desktop, Cursor, or Windsurf (via MCP)

This Actor is also reachable as a scoped MCP tool through Apify's own hosted @apify/actors-mcp-server at https://mcp.apify.com. The ?tools= query string below scopes the connection to just this one actor (stefano_seggio/cordoba-compras-monitor) — not the full Delta Registry fleet. For the full 28-actor closed-scope configuration, see MCP_INTEGRATION.md in the delta-registry-website repo.

Claude Desktop

Add to %APPDATA%\Claude\claude_desktop_config.json (Windows) or ~/Library/Application Support/Claude/claude_desktop_config.json (macOS). Claude Desktop connects through the mcp-remote stdio bridge, not a direct URL — and mcp-remote does not expand shell environment variables inside the JSON string, so paste your real token as a literal value below and keep this file out of version control:

{
  "mcpServers": {
    "delta-registry-cordoba-compras-monitor": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://mcp.apify.com/?tools=stefano_seggio/cordoba-compras-monitor",
        "--header",
        "Authorization: Bearer ${APIFY_TOKEN}"
      ]
    }
  }
}

Cursor

Add to .cursor/mcp.json (project-scoped) or ~/.cursor/mcp.json (global). Cursor uses native HTTP transport:

{
  "mcpServers": {
    "delta-registry-cordoba-compras-monitor": {
      "url": "https://mcp.apify.com/?tools=stefano_seggio/cordoba-compras-monitor",
      "headers": {
        "Authorization": "Bearer ${APIFY_TOKEN}"
      }
    }
  }
}

Windsurf

Add to ~/.codeium/windsurf/mcp_config.json. Windsurf uses serverUrl, not url — and its ${env:...} syntax genuinely does resolve from the environment (unlike Claude Desktop's mcp-remote bridge above):

{
  "mcpServers": {
    "delta-registry-cordoba-compras-monitor": {
      "serverUrl": "https://mcp.apify.com/?tools=stefano_seggio/cordoba-compras-monitor",
      "headers": {
        "Authorization": "Bearer ${env:APIFY_TOKEN}"
      }
    }
  }
}

In every config above, replace ${APIFY_TOKEN} (Claude Desktop, Cursor) or set the APIFY_TOKEN environment variable (Windsurf's ${env:APIFY_TOKEN}) with a real token from Apify Console → Settings → Integrations.

}

Field	Description
nroCotizacion / record_id	The tender process number, e.g. 2026/000091 — this source's own identifier
tipoContratacion	Contract/procedure type, e.g. "Licitacion Publica"
servicioAdministrativo	The issuing agency
jurisdiccion	The government jurisdiction the tender falls under
fechaInicio / fechaFinalizacion	Publication and closing/opening date and time
estado	Current status (e.g. "Publicada", "En Proceso")
prorroga	Whether the deadline has been extended. On a CLOSED record this is the tender's real last-observed value, not a fresh read; null means that value wasn't available (an older, pre-upgrade tracked entry) — never read null as "not extended"
items[].renglon / cantidad / precioReferencia / presupuestoOficial	Line items with quantity, reference price and official budget, extracted inline from the listing fetch — no extra request needed
telefonoContacto	Contact phone number published with the tender
event_type	NEW_LISTING, STATUS_CHANGE, UPDATED, or CLOSED in delta mode (onlyNew: true); UNCHANGED is also possible on a full run (onlyNew: false), where every active tender is returned rather than just what changed
previousEstado	The estado this tender was last seen under, set only on a STATUS_CHANGE record
scraped_at / is_new	ISO timestamp of extraction, and whether this nroCotizacion was previously unseen
contentHash	The SHA-1 content fingerprint used to detect UPDATED amendments between runs (see src/fingerprint.ts)
source_url

Reliability & Delta Engine

• Retries with backoff. Every request — the initial GET and each pagination POST — retries up to 4 times with exponential backoff before the run gives up and returns what it has gathered so far.
• TLS chain handled by the HTTP client. The source's server sends only its leaf certificate, not the required intermediate. The actor's impit-based transport (src/fetchTenders.ts) validates the chain correctly on its own by default — live-verified against the real source; see AGENTS.md's "HTTP transport: impit" section. The Dockerfile's earlier NODE_EXTRA_CA_CERTS fix (for the previous Node-native HTTP client) is left in place as a dormant fallback, not removed.
• Delta state persisted safely. A tender is only marked "seen" once it is actually pushed to the dataset this run, so one held back by maxItems stays correctly eligible for detection next run rather than silently dropping out of tracking.
• CLOSED is only ever reported against a complete walk. A run truncated by maxItems skips (and logs) closure detection rather than guessing that a missing tender has closed.
• CLOSED records carry real last-known field values, not blanks. The source has no per-tender page to re-fetch once a tender has left the active list, so servicioAdministrativo, fechaInicio, fechaFinalizacion, prorroga, items and telefonoContacto on a CLOSED record are the tender's actual values as of its last observation (persisted alongside estado in the delta state), never fabricated empty/false placeholders. prorroga is null only for a tender tracked before this field existed.
• Deduplicates against live inserts. New tenders can be published mid-walk, shifting later rows into duplicate positions across consecutive page fetches; every walked row is deduplicated by nroCotizacion so a mid-run insert can't produce duplicate dataset records.
• Change detection uses a real SHA-1 content fingerprint (src/fingerprint.ts), computed over the tender's stable fields, and compared against the last-seen estado and hash stored per nroCotizacion in a named key-value store that survives between scheduled runs.

Why not just scrape it yourself

• Zero infrastructure. No container to keep patched, no headless-browser runtime to maintain — the actor runs on Apify's platform on your own schedule.
• No proxy or session babysitting. The source blocks non-residential, non-Argentina IPs outright and serves an incomplete TLS chain; both are already handled (Residential+AR proxy, impit's own TLS chain validation) so you don't debug ConnectTimeoutErrors or certificate failures yourself.
• The stateful postback flow is already solved. This portal's pagination is a ViewState/EventValidation ASP.NET grid, not a paged URL — replicating that form state correctly, including the sliding pager window, is exactly the kind of brittle, easy-to-get-subtly-wrong logic this actor absorbs.
• Built-in delta detection. Change tracking (new / status-changed / amended / closed) is maintained for you in a persisted key-value store between runs — you get a diff, not a list to diff yourself.

Known limitations

• No stable per-tender URL. This ASP.NET portal has no plain per-tender deep link — every "Ver Detalles" control is a session/ViewState-bound postback, not a URL — so source_url points at the general listing page rather than the specific record.
• CLOSED requires a complete walk. If maxItems cuts a run's page walk short, a previously-tracked tender missing from that partial fetch might simply be past where the walk stopped, not actually closed — so CLOSED detection is skipped on a truncated run rather than guessed.
• Delta mode is a post-filter, not a pagination shortcut. Córdoba's listing is not reliably sorted newest-first end to end, so onlyNew still walks the full register up to maxItems before filtering, rather than risking a missed tender by stopping early.
• dateRange reflects the source's own declared publication date, not an independently verified first-seen timestamp.
• No contractual SLA. This is an independently developed and maintained actor; bug reports and feature requests go through the Apify Store issue tracker and are typically triaged within about 48 hours.
