📜 🇸🇬 Singapore GeBIZ Tender & Award Change Watch

GeBIZ shows you today's listing, not what changed. This is a seed-zero change feed: when a Singapore government tender opens, changes, closes, is cancelled, or reaches an award state, you get a structured delta with before/after — not another full scrape to diff yourself.

Output is one tender_record row per result; billing is pay-per-event, the value event being one tender/award delta (a $0.02 start fee per run, then $0.05 per tender/award delta plus one $0.10 source check per run that reads the source). Source: www.gebiz.gov.sg.

Use cases by team

• Suppliers & bid teams: Route matching opportunities to bid owners the run they appear, and get told when one changes under you.
• Procurement & compliance teams: Retain dated public status records with before/after evidence of each change.
• Award & incumbency analysts: Catch the PENDING_AWARD → AWARDED transition rather than polling for it.
• Researchers: Study public agency and category behaviour over time from a deterministic, bounded feed.

The run finished with the status message: CAPPED: reason=CAPPED_MAX_PAGES; records=10; opportunities_found=6190

✅ What you get

One of three record types, discriminated by record_type: tender_record, tender_delta, or source_receipt.

Each row is flat JSON with these fields (from the dataset schema and the sample run; a field the source does not publish for a given row is null):

• record_type (string) — Discriminator.
• document_number (string/null) — GeBIZ document number; primary source identity for tender records.
• reference_number (string/null) — Agency reference number when printed on the card.
• opportunity_type (string/null) — Qualification, Quotation, Request for Information, Tender, or Tender Lite.
• status (string/null) — Lifecycle status of the opportunity.
• title (string/null) — Opportunity title as printed on the card.
• agency (string/null) — Publishing agency label.
• procurement_category_parent (string/null) — Parent procurement category label.
• procurement_category_leaf (string/null) — Leaf procurement category label.
• published_at (string/null) — Publication date-time (Asia/Singapore offset).
• closes_at (string/null) — Closing date-time (Asia/Singapore offset) when printed.
• submission_method (string/null) — Submission method when printed on the card.
• awardee_names (array/null) — Publicly displayed awardee names (null unless a public award display exists).
• award_value_sgd (number/null) — Publicly displayed award value in SGD (may be absent or withheld).
• detail_fetched (boolean/null) — Whether a logged-out public detail page was fetched for this record.
• source_url (string) — Exact public GeBIZ URL supporting this item.
• observed_at (string) — RFC3339 UTC time after shape validation.
• source_hash (string/null) — 64-char SHA-256 over the substantive tender fields.
• delta_type (string/null) — tender_delta only.
• composite_key (string/null) — tender_delta: upper(opportunity_type)|upper(punct-stripped document_number).
• before (object/null) — tender_delta: prior tender_record snapshot (null for NEW).
• after (object/null) — tender_delta: current tender_record snapshot (null for confirmed-missing CLOSED).
• changed_fields (array/null) — tender_delta: sorted changed field names (empty only for NEW).
• baseline_observed_at (string/null) — tender_delta: observed_at of the baseline snapshot (null for NEW).
• current_observed_at (string/null) — tender_delta: observed_at of the current run.
• missing_complete_runs (integer/null) — tender_delta: count of complete runs the record has been absent.
• source (string/null) — source_receipt: GEBIZ_PUBLIC_LISTING.
• terminal_state (string/null) — source_receipt only.
• canary_passed (boolean/null) — source_receipt: whether the source-shape canary passed.
• pages_completed (integer/null) — source_receipt: listing pages parsed.
• pages_planned (integer/null) — source_receipt: listing pages planned.
• requests_attempted (integer/null) — source_receipt: HTTP attempts.
• requests_succeeded (integer/null) — source_receipt: HTTP successes.
• requests_failed (integer/null) — source_receipt: HTTP failures.
• items_observed (integer/null) — source_receipt: cards observed.
• items_emitted (integer/null) — source_receipt: records emitted.
• pagination_complete (boolean/null) — source_receipt: traversal completed.
• reason_code (string/null) — source_receipt: stable terminal reason (null for NORMAL).
• message (string/null) — source_receipt: human message (null for NORMAL).

What you get

• tender_delta — NEW, CHANGED, CLOSED, PENDING_AWARD, AWARDED, CANCELLED, NO_AWARD, REAPPEARED, each with before/after and changed_fields
• tender_record — a normalized listing snapshot: document and reference number, type, status, title, agency, category, published/closes dates, source_hash
• A closure grace window (closureGraceRuns) so a listing that briefly drops out is not reported as closed
• missing_complete_runs on each delta, so you can see the evidence behind a closure call
• source_receipt every run — terminal state, canary result, page/request counters, never billed

Every run also writes a RUN_RECEIPT record to its key-value store with the source checks it made and the counts it charged — diagnostics never land in the paid dataset.

⚙️ Sample inputs

1. Quick start — the Store example (this is what the sample above came from)

{
  "maxPages": 1,
  "maxItems": 10,
  "publishedWithinDays": 30,
  "maxDetailRequests": 0,
  "watchMode": false
}

The sample run charged exactly: 1 × $0.02 apify-actor-start + 0 × $0.05 tender_delta + 10 × $0.10 tender_record + 1 × $0.10 source_check = $1.12 on the Free tier — snapshot preview rows are delivered unbilled; only the source check and the start fee were charged.

2. A smaller, narrowed run

{
  "maxPages": 1,
  "maxItems": 5,
  "publishedWithinDays": 30,
  "maxDetailRequests": 0,
  "watchMode": false
}

Caps the run at 5 rows; same billing shape as the sample run above.

3. Watch mode on a schedule

{
  "maxPages": 1,
  "maxItems": 10,
  "publishedWithinDays": 30,
  "maxDetailRequests": 0,
  "watchMode": true
}

The first run seeds a private baseline and emits zero deltas; every later run emits one row per change, billed at $0.05 each plus the $0.10 source check.

🔧 How it works

Source. The actor reads www.gebiz.gov.sg — endpoints: https://www.gebiz.gov.sg, https://www.gebiz.gov.sg/ptn/opportunity/BOListing.xhtml, https://www.gebiz.gov.sg/ptn/opportunity/directlink.xhtml, https://www.gebiz.gov.sg/robots.txt. Public pages and feeds only; nothing behind a login.

Transport. Plain HTTPS from the Apify platform, no proxy. robots.txt is read first and a disallowed path is never fetched.

Watch semantics. Snapshot mode (watch_mode: false) returns a preview. Watch mode keys every record on a source-native id, stores a private baseline in a named key-value store, and on each later run emits one delta row per change (new / changed / removed). A blocked fetch is never diffed, so a source outage cannot show up as a mass removal.

Terminal states. A run ends NORMAL, CAPPED (your cap was reached), PARTIAL (something was withheld and the message says what), GENUINE_EMPTY (the source was read and truly had nothing in scope) or BLOCKED (the source refused or changed shape — the run FAILS loud and bills nothing). A zero-row run is never reported as a silent success.

Charging. Each tender/award delta is charged at the moment it is pushed (tender_delta); a row that fails to charge is not delivered, so the dataset count always equals the charged count. One source_check is charged per run that actually read the source.

How it works

Configure agencies, categories, opportunity types, states and keywords. It reads only the public, logged-out GeBIZ business-opportunity listing, normalizes each listing into a tender_record with a source_hash, and diffs against a private baseline. The first watch run stores the baseline and emits no alerts; later runs emit only qualified tender_delta events with before/after snapshots and changed_fields. Closure is grace-windowed over closureGraceRuns, so a transient disappearance does not fire a false CLOSED. Snapshot mode exists, but the product is the recurring change feed.

Compliance & honest limits

• Public, logged-out GeBIZ listing only — no login, CAPTCHA, paywall, or access-control defeating.
• The first watch run seeds a baseline and emits zero deltas by design.
• Detail-page enrichment is off by default (includePublicDetail, maxDetailRequests: 0) to keep runs bounded and polite.
• A closure is reported only after closureGraceRuns consecutive complete runs without the listing — deliberately conservative.
• A source-confirmed empty listing is GENUINE_EMPTY; truncated runs are PARTIAL; exhausted retries are BLOCKED. Receipts are never billed.

Preview vs Watch mode

• Preview / snapshot (watchMode = false): returns current GeBIZ tender records for the filter and bills one tender_record per emitted row. One-off; no baseline.
• Watch (watchMode = true): seeds a private baseline on the first run (zero deltas, no per-record billing), then emits only qualified tender_delta rows against it. A zero-delta poll over a complete/CAPPED read charges a single source_check; active runs bill via tender_delta and are not double-charged. source_receipt diagnostics go to the RUN_RECEIPT key-value record and log — never the dataset.

What is not done. No login, no cookie or CAPTCHA bypass, no private or personal-account data, no browser automation.

⏰ Set it on a schedule

A single run is a snapshot. The value is the feed: open the actor in Apify Console → Schedules → Create new, add this actor with input 3 above (watch_mode: true), and pick a cadence:

• Daily — 0 7 * * * (07:00 UTC): catch changes within a day.
• Weekly — 0 7 * * 1: a Monday digest.

Each run is independent; keep the same input on the schedule so the results stay comparable. Schedules can also POST results to a webhook (Console → Integrations).

💰 Pricing example

Event	Free	Bronze	Silver	Gold
Actor Start (apify-actor-start)	$0.02	$0.02	$0.02	$0.02
Tender/award delta (tender_delta)	$0.05	$0.04	$0.04	$0.03
Tender record snapshot (tender_record)	$0.10	$0.09	$0.08	$0.07
Source check (source_check)	$0.10	$0.09	$0.08	$0.07

Worked at the live Free-tier price (watch mode, one delta per change):

• 8 tender/award deltas: $0.02 start + $0.10 source check + 8 × $0.05 = $0.52
• 25 tender/award deltas: $0.02 start + $0.10 source check + 25 × $0.05 = $1.37
• 200 tender/award deltas: $0.02 start + $0.10 source check + 200 × $0.05 = $10.12

A run that delivers zero rows charges the $0.02 start fee plus the $0.10 source check (the source was read and reported empty). A BLOCKED run (source refused) fails loud and charges no value event. The start fee is charged once per GB of run memory; the default run memory is 1024 MB.

Yield on the sample run: CAPPED: reason=CAPPED_MAX_PAGES; records=10; opportunities_found=6190. maxItems is a hard ceiling on what is delivered and billed, never a target.

⚖️ Legal & ToS

This actor reads public, logged-out pages and feeds published by www.gebiz.gov.sg. It collects only what the source publishes to any visitor, keeps to the source's robots rules (checked on every run), identifies itself, and does not access accounts, private data or anything behind authentication. Use the output in line with the source's terms and your local law; the intended use is B2B research and monitoring.

❓ FAQ

Q: Do I need an API key or a login?
A: No. The source (www.gebiz.gov.sg) is read logged-out; the input schema has no key field and the actor carries no secrets.

Q: Why did my run return 0 rows?
A: Read the run's status message. GENUINE_EMPTY means the source was read and had nothing in scope for your input (in watch mode the first run always seeds the baseline and returns zero deltas); BLOCKED means the source refused and the run failed without billing a value event — retry later or narrow the input. A zero-row run bills the start fee plus one source check.

Q: How many rows can one run return?
A: Up to maxItems (default 200). Raise the cap for a bigger run; you pay per delivered row.

Q: What does watch mode remember between runs?
A: A private baseline of source-native record ids in a named key-value store. Each later run diffs the live source against it and emits only changes.

Q: How fresh is the data?
A: Every run reads the source live at run time; nothing is cached between runs except the watch baseline. Put it on a schedule for a continuous feed.

Q: What formats can I export?
A: The dataset downloads as JSON, CSV, Excel, XML or RSS from the run's Dataset tab or the Apify API, and any run can push to a webhook or integration.

Q: How is this different from the other public procurement watches actors?
A: Same output shape and billing model; this one covers www.gebiz.gov.sg. The siblings under Related Actors cover the other sources or slices — run several on one schedule for a combined feed.

🆘 Troubleshooting

• Run FAILED with BLOCKED → the source refused the request or changed its page shape → nothing was billed beyond the start fee; retry after a while, and if it persists open an Issue with the run id.
• Status says CAPPED → your cap (maxItems) was reached → raise it for a bigger run.
• Input validation error on start → a field is outside the schema's allowed values → start from the Quick start block and change one field at a time.
• Run TIMED-OUT → a very wide request on a slow day → raise the run timeout in Run options or narrow the input; what was delivered before the timeout is still in the dataset.
• First watch run shows no deltas → expected: it seeds the baseline; changes appear from the second run.
