Tenders in Ukraine API

⭐ Beginner's Pick Business / No Auth Required Beginner HTTPS
Free to Use Varies (check documentation)

Overview

The Tenders in Ukraine API from tenders.guru offers free, unauthenticated access to Ukrainian public procurement data including tender titles, contracting authorities, contract values, and awarded suppliers. The data is sourced from Ukraine's Prozorro open procurement system, one of the most transparent public procurement platforms in the world. It is ideal for anti-corruption research, market analysis, or civic tech applications.

💡

Beginner Tip

Because the underlying data comes from Prozorro, you can cross-reference records at https://prozorro.gov.ua for additional detail — use the tender ID from the API response as a search key.

Common Errors & Troubleshooting

Empty results on recent dates Ingestion lag means very recent tenders may not yet appear in the API
Query tenders from at least 24-48 hours ago to ensure the data has been processed and indexed
Character encoding issues Ukrainian Cyrillic characters not rendering correctly if the HTTP client does not handle UTF-8
Explicitly set Accept-Charset: utf-8 header and ensure your output stream uses UTF-8 encoding
Timeout on large pages Requesting too many records per page at once
Use per_page=10 or per_page=25 rather than the maximum to keep response times fast
