CrawlwrenBot
If you saw this User-Agent in your logs, this page explains who we are, what we fetch, and how to reach us or opt out.
CrawlwrenBot/0.1 (<tool>; +https://crawlwren.com/bot)
<tool> names the tool making the request: uk-eu-tenders, global-tenders, sam-gov-opportunities or gleif-lei-lookup.
Who we are
Crawlwren makes small data tools on official open data: public tender notices and LEI records. The tools run on the Apify platform when someone starts a run.
What we fetch
- Official APIs and open-data files that publishers provide for reuse: UK Contracts Finder and Find a Tender, TED, SAM.gov’s public extract and API, GLEIF, CanadaBuys open data, BOAMP, TenderNed, AusTender, the EU Funding & Tenders search API and the World Bank procurement APIs.
- Only the records a run asks for (a date window and filters), not whole websites.
- We don’t log in, solve CAPTCHAs, rotate IPs or proxies, or impersonate a browser. If a source blocks us, the run stops for that source and reports it. We don’t work around blocks.
Rate limits
