Open Contracting OCDS Tenders API — public tenders from several countries in one schema

Open Contracting (OCDS) Tenders API reads public procurement from national publishers and returns one flat row per tender: buyer, title, CPV, value, status, tender period, awards and a link. Publishers today: MTender (Moldova), Contracts Finder and Find a Tender (UK), Prozorro (Ukraine).

What it does

• Search - by publisher, keywords, CPV, value, buyer and date window.
• Monitor - only new or changed tenders since the last run.
• One schema for all publishers, including award suppliers when published.
• More publishers are added by extending the reader list.

Who it's for

• Tender aggregators and alert services
• BI and market-intelligence teams
• Researchers of public spending
• Exporters scanning foreign procurement

change-event	Alert event	$0.03	$30

Apify platform usage (compute, storage) is included in the event prices. Set Maximum cost per run in the run options to cap spending; the Actor stops cleanly when the limit is reached. Apify subscribers on Bronze, Silver and Gold plans get automatic discounts on the event prices.

FAQ

Is it legal to use this data? The Actor only reads official open data from national OCDS publishers. Open government data under each publisher's licence. Every row carries source and sourceUrl so you can attribute it. No captcha, login or personal data of private individuals is bypassed or collected.

How fresh is the data? Each row has dataAsOf - the publication date of the source file or API. If the publisher stops updating, dataAsOf stops moving and the daily self-test run fails, so you can tell stale data from a broken Actor.

What happens when nothing is found or the source is down? You get a not_found or source_error row and you are not charged. The Actor never fails silently with an empty dataset.

How do I get alerts? Create a Task with mode: monitor, schedule it (hourly or daily) and add a webhook, or connect the Apify integration in n8n, Make or Zapier. Only new, changed and removed records are returned and charged.

Which countries are covered? Moldova, the United Kingdom and Ukraine today.
