If you found this page, you probably saw our User-Agent in your access logs:
Heistbot/1.0 (+https://heistcorp.com/hello; contact@heistcorp.com)
That's us — Heist Corp, an independent EU-based price-comparison operator. We crawl public product feeds from collectibles retailers (LEGO, trading cards) and surface the lowest current price to consumers. No fake "was/now" badges, no paid placements, no dark patterns.
How we crawl
Shopify /products.json, Adtraction / Partner-ads XML feeds, public Algolia indices, and lightly-paginated public HTML.
Never authenticated endpoints, never private APIs.
One scheduled run per retailer per day. Per-feed page-loft to avoid runaway pagination. We don't hammer; we don't retry-storm.
All outbound traffic egresses from a single Hetzner host in Falkenstein, DE. Easy to allow-list or rate-limit on your end — we welcome both.
Our User-Agent links back here with a working contact address. No browser impersonation. If you block us, we stop.
How to reach us
Mail us and we'll remove your shop the same day. No questions, no friction. You can also just block our User-Agent — we won't try to evade it.
contact@heistcorp.com →If we're hitting rate-limits, 5xx responses, or your feed structure changed and we missed it — let us know. We'd rather get a heads-up than keep retrying blindly.

Every product on our sites links straight to a retailer. If you want those clicks tracked through your affiliate network — or just want a direct integration with cleaner data — we're flexible. Affiliate commissions keep the lights on; clean data and fair ranking are what keep users coming back.
Networks we're on: Adtraction, Partner-ads, Awin, Rakuten LinkShare, Daisycon. Easy to add others.
Direct feed integration: If you'd rather skip the networks, we'll consume whatever format works for you — XML, JSON, CSV.
Plain links also fine: If you don't run an affiliate program, we'll still link to you. We pick retailers on data quality and price, not commissions.
