Convert tender change inputs into structured procurement intelligence with extracted fields, classifications, changes, and source evidence.

Who this is for

Bid teams, procurement analysts, sales operations, consultants, and public-sector vendors use this actor when they need focused tender change output instead of a broad generic scraper or manual checking.

Buyer outcomes

• Convert tender change tender inputs into structured procurement intelligence.
• Prioritize review with extracted requirements, normalized language, classifications, changes, confidence, and source evidence.
• Route structured results into bid, sales, procurement, analyst, or compliance workflows.

Sources monitored

• TED Search API
• oeffentlichevergabe.de Open Data
• SIMAP Switzerland
• Austria USP tender search/publication media
• Apify datasets/storage

Inputs

• sourceMode: use sample for a smoke run or configured tender page/PDF/source modes.
• startUrls: tender pages, PDFs, notices, buyer pages, or public procurement source URLs.
• sourceIds: approved tender, document, buyer, or procurement source identifiers.
• maxItems: bounded number of transformations, classifications, or changed tender records.
• watchlistTerms: buyer, CPV/category, requirement, region, language, or change terms.
• webhookUrl: optional destination for bid, procurement, or analyst review.
• outputMode: use sample records for Store validation or production output for normal runs.

How it transforms the input

• Input: tender page, PDF, buyer history, change record, CPV/category text, or multilingual tender text.
• Transformation: extract requirements, classify categories, normalize language, compare changes, or enrich buyer context.
• Output: structured tender intelligence with input reference, transformation type, extracted fields, confidence, and source evidence.

Outputs

The actor returns tender transformation records with input reference, extraction/classification/change output, source evidence, confidence, and review notes.

Family-specific fields to expect:

• inputReference: Tender page, PDF, buyer, or text input being transformed.

• transformationType: Classification, extraction, normalization, or change detection.

• extractedFields: Structured fields extracted from the input.

• confidence: Confidence for the transformation.

• sourceUrl: Source evidence URL.

• recordId: Stable record ID for exports, dedupe, and downstream joins.

• title: Human-readable record title for review and export.

• sourceName: Source identifier used to trace where the record came from.

• sourceUrl: Direct source URL for review and audit.

• dedupeKey: Stable key used for delta mode and duplicate suppression.

• retrievedAt: Timestamp showing when the actor retrieved or generated this record.

• score: Normalized field for filtering, routing, or downstream review.

• scoreReasons: Buyer-readable explanation for the score or match.

• confidence: Normalized field for filtering, routing, or downstream review.

• errors: Normalized field for filtering, routing, or downstream review.

• runSummary: Run-level summary for counts, filters, charges, and next actions.

Pricing

This actor uses Apify pay-per-event pricing. Current public listing guidance: $29-$49 / 1,000 launch validation records until public data proof is complete. Charges are tied to buyer-visible value events such as change-alert, dataset-processed, record-saved, enriched-record. Small validation runs are supported so you can inspect output before scaling a schedule.

• change-alert: Charge when Tender Change Monitor produces Changed Item. Typical price: $0.022. A run that produces 10 matching records charges only for the matched buyer-value events and remains capped by the run limit.
• dataset-processed: Base charge when Tender Change Monitor writes a non-empty default dataset. Typical price: $0.011. A run that produces 10 matching records charges only for the matched buyer-value events and remains capped by the run limit.
• record-saved: Charge for each buyer-visible result saved by Tender Change Monitor. Typical price: $0.003. A run that produces 10 matching records charges only for the matched buyer-value events and remains capped by the run limit.
• enriched-record: Charge when Tender Change Monitor adds match scoring, source evidence, or enrichment to a saved result. Typical price: $0.022. A run that produces 10 matching records charges only for the matched buyer-value events and remains capped by the run limit.
• first-run-cap: Recommended first run budget cap. Typical price: $3.820. Start with the default small run, inspect the dataset, then raise maxItems or schedule recurring runs.

Use cases

• Extract or normalize tender change tender inputs before manual procurement review.
• Turn PDFs, pages, buyer history, changes, or classifications into structured rows.
• Attach confidence, source references, and extracted fields for auditability.
• Route structured procurement intelligence to sales, bid, or analyst workflows.

Trust and compliance

• Uses TED Search API, oeffentlichevergabe.de Open Data, SIMAP Switzerland.
• Keeps source URLs and source identifiers in output records for auditability.
• Does not require private credentials unless a source is explicitly configured for approved authenticated access.

Limitations

• Results depend on public-source availability, source uptime, and source update cadence.
• Public sources can revise records after publication; rerun scheduled tasks for fresh evidence.
• Scores and match reasons are decision-support signals, not legal, financial, procurement, medical, safety, or regulatory advice.
• Large production runs can cost more than the default smoke run; start small, inspect output, then scale schedules.

FAQ

Can I run this without URLs? Yes. The default sample mode is designed to succeed without user-supplied URLs, and URL-backed runs can use startUrls when needed.

Can I schedule it? Yes. Use sinceLastRun, watchlistTerms, and optional webhookUrl to turn the actor into a recurring alert or report workflow.

How do I verify value before scaling? Run the recommended first-run input, review the sample output fields, then increase maxItems or schedule recurring runs after the dataset matches your use case.
