Exemples de code

La même recherche dans plusieurs langages : trouver les sites qui embarquent un script donné, parcourir les pages de résultats et patienter poliment lorsqu’on vous demande d’attendre. Placez votre clé dans une variable d’environnement plutôt que dans le fichier.

La même chose, sous forme de petits clients avec une ligne de commande - en n’utilisant que la bibliothèque standard : Python, JavaScript, PHP, Go, Ruby. Dans un tableur : Google Sheets. Dans une table de prospection : Clay.
