Bot signals — Search & SEO crawler
Arquivo.pt published web archiving crawler ranges.
01 — Verification
Only from what Arquivo.pt Web Crawler publishes about itself. No third-party blocklists, no behavioural guesses. Live address counts change with every publication, so check the official file for the current list.
risk.is_crawler
02 — In the response
A lookup of a Arquivo.pt Web Crawler address sets risk.is_crawler. The flags come with geolocation and network data in the same response, for Pro API keys.
The response says which kind of bot an address belongs to, not which operator. Pair it with the user agent: a request that claims to be Arquivo.pt Web Crawler but doesn't match is unverified.
