Limits and pitfalls

• At most 100 per page. No documented rate limit; count with size=1 and the date filters. tested
• The web service is only complete from 2022: 2020 has 3,221 publications, 2021 rises from 521 (January) to 1,942 (December). Use the annual files for older years. experience
• The path without v2 (…/tenderned-rs-tns/publicaties) redirects with 301 to v2. No OpenAPI description was found (api-docs and swagger return 404); the web service is not in the TenderNed Notice Service specification. tested
• A publication can have several contract types: the counts per typeOpdracht (L+D+W) add up to more than the total. experience
• Annual files (OCDS 1.1 JSON, CC0): 58 MB (2016) to 116 MB (2025), topped up every six months; Range requests work to inspect the structure. They contain names, e-mail addresses and phone numbers of contact persons. experience
• robots.txt (/robots.txt redirects to /cms/robots.txt) does not exclude /papi/. tested
