How to scrape Idealista without getting blocked

What protects Idealista?

DataDome

Idealista uses DataDome to protect both its desktop site and its mobile JSON API. Each market (idealista.es, idealista.pt, idealista.it) shares the same protection tier — high sensitivity, low tolerance for repeat visitors from a single IP.

Listings disappear from search results after 6–8 requests from the same datacenter IP, even before the slider CAPTCHA fires. Sessemi rotates through residential IPs in the target country and replays validated DataDome cookies so each scrape gets a fresh slot.

Scrape Idealista with one API call

Send the URL, get clean HTML back. Sessemi handles DataDome, IP rotation, and session management automatically — no per-solve fees.
