## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## 🇨🇦 CanadaBuys Tender Watch — Federal Opportunities & Awards

Government of Canada opportunities move fast and the open-data CSV is a moving target. This turns the official CanadaBuys tender-notice feed into a deduplicated, delta-only watch by buyer, province, and UNSPSC — with a receipt on every run.

### What you get

- `tender_notice` — open and amended tender-opportunity records with buyer, category, value, closing date and source URL
- `award_notice` — award records with winner names/ids, incumbent keys, award value, and the linked tender
- `procedure_delta` — watch-mode change events: new opportunity, notice updated, tender-to-award, incumbent change
- Province and UNSPSC/GSIN targeting so a national feed narrows to the segment you actually bid on
- `source_receipt` on every run — terminal state, counts, and a source-shape canary result, never billed

### Use cases by team

- **Suppliers & bid teams:** Watch the departments and UNSPSC categories you sell into and catch new solicitations on publication day.
- **Regional resellers:** Filter to your provinces so a federal feed becomes a local pipeline.
- **Incumbency analysts:** Track award outcomes and incumbent turnover across federal buyers.
- **Procurement-intelligence vendors:** Ship a bounded, deduplicated Canadian feed without owning the CSV-drift problem.

### Example inputs

*Last 7 days, everything (default window)*

```json
{
  "maxItems": 500
}
```

*Watch one department in two provinces*

```json
{
  "buyerNames": [
    "Public Services and Procurement Canada"
  ],
  "provinces": [
    "ON",
    "QC"
  ],
  "watchMode": true,
  "baselineId": "pspc-on-qc"
}
```

*UNSPSC targeting over an explicit window*

```json
{
  "publishedFrom": "2026-07-01",
  "publishedTo": "2026-07-24",
  "unspscCodes": [
    "43230000"
  ],
  "keywords": [
    "software"
  ]
}
```

### 📊 Sample Output

```json
{
  "record_type": "tender_notice",
  "procedure_id": "cb-2026-doc-884213",
  "buyer_name": "Public Services and Procurement Canada",
  "buyer_province": "ON",
  "title": "Software licence renewal",
  "unspsc_codes": [
    "43230000"
  ],
  "estimated_value_cad": 1180000,
  "closes_at": "2026-08-14",
  "notice_kind": "open",
  "language": "ENG",
  "source_url": "https://canadabuys.canada.ca/en/tender-opportunities/tender-notice/884213",
  "observed_at": "2026-07-25T00:00:00Z"
}
```

### How it works

Give it a date window and optional buyer / province / UNSPSC / keyword filters. It reads the **CanadaBuys open-data tender-notice CSV** (`canadabuys.canada.ca/opendata`) as an anonymous public client, normalizes each row into `tender_notice` and `award_notice` records, links awards back to their tender when `linkAwards` is on, and — in watch mode — diffs against a private baseline to emit only `procedure_delta` events. Every run closes with a `source_receipt` whose canary check catches CSV column drift before it can silently corrupt your feed.

### Pricing

| Event | Price (FREE tier) |
|---|---|
| Actor start (`apify-actor-start`) | $0.02 flat, once per run |
| Procedure delta (`procedure_delta`) — **primary** | $0.02 |
| Tender notice (`tender_notice`) | $0.004 |
| Award notice (`award_notice`) | $0.006 |
| Source check (`source_check`) | $0.10, once per run |

Pay-per-event on a four-tier ladder (FREE → GOLD, with Platinum/Diamond floored at the Gold rate). Primary event `procedure_delta`: **$0.02 / $0.018 / $0.016 / $0.0134**. Notices: $0.004 / $0.0036 / $0.0032 / $0.00268 (tender) and $0.006 / $0.0054 / $0.0048 / $0.00402 (award). `source_check`: $0.10 / $0.09 / $0.08 / $0.067. Worked example — a watch run on FREE that finds 12 procedure deltas: $0.02 start + $0.10 source check + 12 × $0.02 = **$0.36**. A seed run or a genuine-zero run charges the start + source check only; receipts are never billed. New to Apify? [Start free](https://apify.com/fpr=2ayu9b).

### Compliance & honest limits

- Public, logged-out official source only — no API key, login, cookie, CAPTCHA, or access-control defeating.
- Client-side targeting: filters are applied to the bounded window this actor fetched, not pushed into the upstream query.
- Watch mode's first run seeds a private baseline and emits **zero** deltas by design — deltas start on the second run.
- A source-confirmed empty window is `SUCCEEDED-0: GENUINE_EMPTY`; truncated runs are `PARTIAL`; exhausted retries are `BLOCKED`.
- `source_receipt` records are always emitted and are **never billed**.

### FAQ

**Where does the data come from?**

The official CanadaBuys (canadabuys.canada.ca) open-data tender-notice CSV public, logged-out feed. No API key, login, or cookie is used, and no access control is defeated.

**What does watch mode actually do?**

The first run stores a private baseline and emits zero deltas. Every later run emits only `procedure_delta` events keyed on the source-native procedure id — new opportunity, notice updated, tender-to-award, and incumbent change.

**Does zero results mean I was blocked?**

No, and you never have to guess. Every run emits a `source_receipt` with an explicit terminal state: `NORMAL`, `GENUINE_EMPTY`, `PARTIAL`, or `BLOCKED`, plus a source-shape canary result.

**What am I charged when nothing changed?**

The $0.02 start and the $0.10 source check. Deltas are the primary billable unit, so a quiet window is cheap by design. Receipts are never billed.

**How do I bound the window?**

Use `publishedFrom` / `publishedTo` — it defaults to a recent bounded window rather than attempting the full historical archive.

**Can I track a specific buyer or category?**

Yes — that is the main targeting path. Pass `buyerNames`, `provinces`, `unspscCodes`, or `keywords`.

**Will this reconstruct the full contract history?**

No. It is a bounded, deduplicated recurring feed, not a historical archive backfill. That honesty is deliberate.

### Troubleshooting

- **Watch mode emitted nothing?** Expected on the first run — it seeds the baseline. Deltas begin on run two with the same `baselineId`.
- **Zero records?** Check the date window first, then read the `source_receipt`: `GENUINE_EMPTY` means the source really had nothing in that window.
- **Run marked PARTIAL?** Collection was truncated against `maxItems` or a retry budget. Raise `maxItems` or narrow the window and re-run.
- **Filters returning too little?** Filters apply client-side to the fetched window, so widen the date window before widening the filters.
- **Need the untouched upstream payload?** Set `includeRaw: true` to carry the raw source object alongside the normalized record.
