PrinterialsBot

PrinterialsBot collects publicly listed filament and printer prices so that Enkodo’s price comparison can show what a product costs across shops. This page explains exactly what it does, so you can decide whether to allow it.

How to recognise it

Every request it makes carries this User-Agent:

PrinterialsBot/1.0 (+https://printerials.com/bot; [email protected])

It also sends a From header with the same address. We do not rotate IP addresses, use residential or proxy networks, or present ourselves as a browser. Requests come from one fixed address, and if you block it, we stay blocked.

What it fetches, and how often

• Product pages, sitemaps, and public product APIs. Nothing behind a login, a cart, or a checkout.
• At most one request at a time per site, with at least one second between requests, and longer if your robots.txt asks for it.
• A daily pass that re-checks pages we already know, and a weekly pass that re-reads sitemaps. The daily pass sends If-None-Match and If-Modified-Since, so most of it answers 304 Not Modified and costs you almost nothing.

robots.txt

We read robots.txt before anything else and obey it, including Crawl-delay. If we cannot read it, or it answers with an error, we treat your whole site as disallowed and stop. To block us specifically:

User-agent: PrinterialsBot
Disallow: /

That takes effect on our next run, within a day. You do not need to contact us first, though we would rather you did.

If you would rather send us data

A product feed is better for both of us: it is accurate, it is cheaper for your servers than crawling, and it means your prices are represented the way you intend. If you publish a feed, or would like us to stop crawling and use one instead, write to us and we will switch.

Contact

[email protected] reaches the people who run the crawler. We answer questions about what we fetched, remove a site on request, and can tell you exactly which pages we have seen.
